22.2

Tables can now be easily copied to the clipboard and pasted outside of liNear. For example, you can copy the results of the heating load calculation, the radiator dimensioning, storey tables, tables in the network calculations or the layered structure of components including material values and continue to use them with Microsoft Excel or other applications. All tables can be copied using the universal key combination "CTRL "+"C". The function applies to all tables regardless of the module used.

In liNear Building additionally a symbol has been inserted in the upper left corner of the table. Here, the program asks after the execution of the command whether the content of the table should be copied with or without the headlines.

22.2

The functions for displaying elements from liNear Building in the CAD model and vice versa has been fundamentally revised and improved. This makes navigation through the model and calculation much easier. Spaces as well as individual space bounding components are now highlighted in color, regardless of whether the element is located in the current model or in one of its links.

Likewise, the area proportions of objects such as walls and ceilings that result from the room assignment are taken into account, and only the corresponding part of the component in the model is highlighted when it is displayed. There are two modes for showing: If you use the magnifying glass icon, the command is executed once with the selected element and the element is shown in the CAD model. If you activate the fixed mode (magnifying glass symbol with pin), the elements selected in liNear Building will be permanently displayed automatically in the CAD model until the mode is exited again.

The function "Find CAD Element" (pipette symbol) selects the room depending on the view direction in which the element is selected in the CAD model and displays the selected element in this room in liNear Building. Thus, it makes a difference whether you select a door from the corridor side or from the room side.

22.2

In the Locations dialog you can now also create, edit or delete your own regions and locations with climate data. The corresponding buttons located next to the selection of the region as well as below the selection list of the locations open a dialog in which you can change or completely create new data sets. For each input field, a tooltip is provided that briefly describes the calculation(s) for which the respective field is required.  

22.2

The location and integrated climate data for the heating load calculation has been supplemented for Croatia. Likewise, the data for Russia has been updated according to SP 131.13330.2020.

22.2

With the new function Connect components in the discipline waste water, you can now automatically connect consumers such as washbasins, showers, toilets, etc. to collection or downpipes. Of course, the connection is based on the technical guidelines for drainage. The software searches for pipes with suitable media from the selected consumers and automatically constructs the connection of the waste water pipes, including the gradient. The prerequisite is a technically correct framework in terms of construction heights and distances that would also allow connections with the available fittings in reality.

22.2

To make the design of cross sections for your corridor concept even more convenient, an "Undo" function has been added to the cross section editor. In addition, you can now delete elements from your layout with the Del key. When adding pipes, a spacing is now automatically added to the other pipes. The last setting is used for the distance dimension.

22.2

Instead of replacing all existing alias entries in the project when loading a new definition file, you can now decide whether these entries should be replaced or merged with the list to be loaded. This gives you the option of dynamically adding individual sub-lists and thus continuously expanding the overall list depending on the project status.    

22.2

In order to support you even better in using the liNear software, we have extended the help. For the liNear CAD Solutions for Revit you will now also find "recommended procedures" for the effective use of the functions. If you still encounter unexpected behavior when using the software, a look at the "Troubleshooting" will help. Here you will find suggested solutions for the respective function in order to eliminate typical errors.

22.2

In the CAD Browser, you can now also display the product, operating and installation spaces of components that have been defined by the manufacturer. For optimized positioning of the components in the model, these spaces are also transferred and you can then show and hide them in the model as required. In addition to the product, operating and assembly spaces, you can now also show and hide the manufacturer's logo on the components.

22.2

You can now select the individual components of products consisting of several devices one after the other and insert them into the model. A typical example for such products are heat pumps, which usually consist of an inner and outer part. A yellow triangle with an exclamation mark indicates that there are several components within this product. You can then use the display selection list to select the desired component.  

22.2

The help for the liNear CAD browser has been revised and converted to the modern format. Analogous to the help for liNear Solutions for Revit and Building, you will now find the texts in a modern browser view.

22.2

For larger projects, you can now narrow down the displayed rooms even more easily using search terms. The filters for error and ventilation types can also be combined. Via the filtered selection of several rooms in the tree structure, you can now assign common settings to these rooms at once.

22.2

Cross-section splitting often becomes necessary where an air duct with its total cross-section cannot be passed through a structural situation at one point. In such cases, the duct is divided into parallel sections that are brought together again after the obstacle.

The duct network calculation can now detect such situations and calculate them perfectly. The flow paths created by the cross-section splitting are also compared with each other. For each individual flow path, the volume flow rate is determined based on the prevailing pressure loss. In the calculation dialog, you can recognize the sections of the cross-section separation in the area of the sections parts by indentation and colored marking of the section parts numbers.

22.2

In the case of outdoor installations with several protective gratings, the adjusting air volume flows at the gratings are now also calculated. The automatic calculation is activated by default. However, you can still enter values manually. To do this, remove the checkmark from the "calculate" option in the component dialog of the protective grating and enter the desired value. The possibly required pressure loss for the individual flow paths will still be calculated.

22.2

If you decide to use a protective grating with balancing dampers from the liNear CAD Browser, you can now even take the damper position into account for the airflow mechanical balancing of several flow parts. You can choose whether you specify the volume flow rates and the required damper blade position is determined or whether you specify a damper blade position and the adjusting volume flow rates are determined.

22.2

For central air handling units that you have inserted from the liNear CAD Browser, the technical data of the air connections are now also taken into account directly in the duct network calculation. On the one hand, it is checked whether the volume flow and the compression correspond to the results of the connected duct network. On the other hand, the sound levels specified by the manufacturer are used as a source for the sound level calculation for each air connection.  

22.2

In the configuration of the potable water calculation, you can now select the option that when dimensioning closed circular pipes with flow dividers based on VDI 3805 data sets, the flow type is directly taken into account during dimensioning as an additional criterion. In this case, the dimension of the circular pipe is increased until a regular exchange of the water content of the circular pipe is ensured by flushing devices or a sufficiently large peak volume flow rate. 

Furthermore, the analysis of networks with flow dividers has been further improved, so that the calculation time could be shortened, but at the same time more accurate results are obtained when considering hygiene.

22.2

Under Calculation specifications in the gas pipe network calculation, the calculation according to the new technical rules for liquid gas (TRF 2021) has now been added.  

22.2

On the Edit tab, the Copy storey contents function has been added. This allows you to copy all the elements of one storey to another and quickly and easily apply both the architecture and piping and other elements to the same storeys. The necessary layers are created immediately during copying using the layer key. In the dialog you decide whether all elements or only the visible elements of the storey should be copied.

22.1

In order to be able to calculate only partial areas of pipe networks that have been constructed so far, the partial network start is available to you as a substitute for the primary side. In heating and cooling networks you can now specify whether this substitute component should also contain a pump.

22.1

The Rooms dialog of the duct network calculation now contains a filter to display rooms according to various criteria. For example, you can display only those rooms that are to be mechanically ventilated or only rooms with supply air terminals. You also have the option of filtering by a specific error message to speed up troubleshooting.

22.1

The calculation of the minimum flow rate in the Rooms dialog has been extended to include procedure 2 of EN 16798-1. Procedure 2 determines the volume flow with which the limit value of any pollutant is complied with. Both procedures can be combined. The higher volume flow of both cases is given to the room as the minimum volume flow.

You can freely define the pollutants to be taken into account in the dialog. The pollutant designation and the limit value are saved and can thus be used in other rooms or projects. For the pollutant CO2, limit values of three different standards are stored. The release rate of CO2 can be determined depending on the number of persons and their activity.

22.1

With the new printout for rooms from the sound level calculation, you can now prove that the required sound pressure level is maintained in each room. The printout shows the details of the room for the acoustic calculation and all air diffusers in the room with their settings. With the help of this listing, you can quickly identify those diffusers that contribute most to the overall sound level, so that if the required sound pressure level is not met, you have direct starting points where improvements in the system will have the greatest effect.

22.1

The heating and cooling pipe network calculations have been extended by two additional hydraulic circuits. You can now include throttle circuits with two-way control valves and injection circuits with flow controllers in your planning. Both are often used within the cooling design.

22.1

For the correct design of a flow divider, the condition must be considered when there is no extraction in the ring and the ring is only turbulently flushed by a subsequent extraction. In addition to automatic flushing stations, consumers can also be flushing-relevant if regular use is ensured. You can now define the consideration of a flush-relevant consumer in the component dialog. This influences the result of the check as to whether all upstream flow dividers selected via the VDI data source are flushed turbulently.

In addition to the setting in the component dialog of the consumers, the flushing-relevant consumers can also be displayed in the model from the component dialog of the assigned flow divider.

22.1

Within the ventilation design, you can now integrate partial network starts and ends from the library tab simply by selecting the desired duct. This is then automatically placed in the correct size, position and 3D orientation. Subsequent manual rotation or pushing is no longer necessary.

22.1

You can now name your generated tanks directly in the configurator, which will then also be used as its family name. Furthermore, a description of the container is generated as a parameter which makes this information available in the model.

In addition, the calculated volume of the container is now also displayed. This is correctly determined from the information about cover type, geometric dimensions and wall thicknesses. The wall thicknesses are suggested based on a simplified compressive strength calculation and can of course be adjusted manually.

22.1

From now on you can decide whether changes in the liNear properties dialog are to be adopted directly when the mouse pointer leaves the dialog area or whether entries have to be explicitly confirmed. The direct acceptance corresponds to the behavior in the Revit properties dialog. To ensure more convenience when editing properties, you can now set the options so that your entries are only accepted when you click the "Apply" button.

22.1

In the usage and temperature profiles you can now directly draw the values for the respective hour by clicking and dragging in the diagram. Setting the exact values via edit fields is of course still possible.

22.1

The heating load results for each room are now displayed on all structure levels, such as floor levels. In the overview, you can quickly identify anomalies and double-click or use the button to switch directly to the relevant room dialog to make adjustments.  In the room dialog you will now also find a button to return to the previous room overview.

22.0

With version 22, the latest versions of Autodesk Revit and AutoCAD and corresponding verticals are now supported. The following versions are thus compatible:

• Autodesk AutoCAD 2022 - 2019
• Autodesk AutoCAD Architecture 2022 - 2019
• Autodesk AutoCAD MEP 2022 - 2019
• Autodesk Revit 2022 - 2019

22.0

You can now transfer the dimensions of modeled 3D pipes into the network calculations (currently still except gas). This applies to all pipes in Revit and 3D pipes from the liNear 3D Pipe&Power module for AutoCAD and liNear CADinside.

You can choose whether the dimensions should be taken over from all pipes or from a selection. After the calculation, you can clearly visualize any deviations in the dimensions between the designed and calculated pipe.

22.0

For better assignment of linked partial network starts and ends, the connection of the elements in the model can now be comfortably visualized from within in the component dialog by a temporary line in the drawing. 

22.0

The water volume of a heating and/or cooling system is now displayed in the results overview in the calculation dialog and can be used in the central device’s label (e.g. a boiler).

22.0

In the calculation dialog of the air duct network calculation, a filter has been added for all systems on the outside air side and on the room air side. Especially in complex projects with several air handling units and the differentiation between supply and exhaust air, you can quickly select the desired system.

22.0

The potable and waste water calculations have been extended by a total printout of the consumers and the waste water objects.

In this printout, identical consumers are summarized, and their connection values are displayed and summed up. In this way, you get a good overview of the system and have a prepared printout that can be used in particular for official approval procedures.

22.0

The corridor design in early design phases introduced with version 21 has been improved. To enable a faster workflow, the design of cross sections is now done in two steps.

In the first step, you define the type of the pipes or ducts (supply air, supply heating, etc.) and associated dimensions for the corridor. You can then sort and position these in the second step by drag&drop them in the new cross-section editor. By splitting the dimensioning and geometrical arrangement steps, the corridor design is thus even more intuitive and changes in the arrangement can be implemented very quickly in the new editor.

Once created, you can save cross-sections and use them as templates for other cross-sections.

22.0

For an easier transfer of the building structure to liNear Building, you can now manually adjust the building part in the liNear properties dialog of the MEP room in deviation from the setting of the level.

This way you can actively control how the rooms are sorted in liNear Building, which can be especially helpful for rooms on one level that cover several building parts.

22.0

For better coordination, you can now integrate a new construction aid into the model in the exported IFC file.

For this purpose, a separate family has been created with the IFC export marker, which you can find in the libraries and place in a suitable position in the model.

This facilitates the overlaying of the multiple (sub)models in the IFC viewer if different coordinates are stored and thus the models are not suitably overlaid. They can then be easily aligned by positioning the coordination point.

22.0

The labels for the provision for voids have been extended by the height information. Here you now have the option of specifying the distance to a selected reference height (e.g. upper edge of unfinished floor).

22.0

The user interface of liNear Building has been modernized. Besides a visual update, the control elements have been unified and the overview has been improved.

22.0

The help for liNear Building has been completely revised and converted into a modern format.

Analogous to the help of liNear Solutions for Revit, you will now find the help content in a modern browser view. All topics are presented in a workflow context and the content is divided into instructions for action, concepts and descriptions of interface elements.

Especially with the powerful search function, you can quickly get to the right place in the help.

22.0

When inserting radiators from Building into your CAD program, you can now choose between three geometric levels of detail. In the simplest geometry, the radiator is displayed as a block, just like before. Newly added are the simple and the detailed geometry from the VDI definition.

You make this setting once when selecting the radiators to be dimensioned and can adjust it later within the VDI options if desired.

22.0

In the design of panel heating systems, the system is now optionally designed for the entire surface of the room, even in the case of partial floor areas with different adjacent temperatures.

Depending on the selected system, this is possible for underfloor as well as for wall and ceiling systems.

The design area is thus separate from the area of the components that are required in the heating load calculation. This is the case, for example, when a floor of a room is adjacent to two differently heated rooms.

For the calculation of the losses of the panel tempering the passed temperatures are considered, but the extension of the layout is now independent of these surfaces

22.0

For a quick check of the room heating loads, an overview of the heating load results per room has been added on the project level. This allows you to quickly identify rooms with unusually high heating loads and specifically check the entries there.

22.0

In addition to radiators and/or panel heating, the heating load of a room can also be partially covered by a ventilation system in which the air blown into the room is heated by an air heater.

In the heating load calculation according to EN 12831-1, you can now immediately see which part of the heating load is already covered by an air heater and which is used as a basis for the dimensioning of radiators and panel heating systems.

For the design of air heaters in ventilation systems, the performances are summarized in the new expression "Air heater balance".

22.0

Manual entry of rooms for the heating load calculation is now even faster and easier. By clicking into an empty field on the floor or apartment level, a context menu opens to select a room type, which is stored in the room templates.

The selection creates the rooms directly and you can then adjust the dimensions so that you can start entering the room components directly in the rooms.

22.0

In the dynamic cooling load calculation, you can create room groups to assign common internal loads to groups of rooms. For quick and easy assignment of rooms to a room group, a filter has now been added to the dialog that allows you to conveniently filter rooms with the same names and then add them to the room group.

• New in the range is the Oventrop "Aquastrom K" cold water circulation valve.
• Warm water storages, instantaneous water heater and manifolds now complete the CAD library.

21.2

With the help of the new classification manager, you have the option of structuring model contents on the basis of different aspects and implementing uniform classification standards throughout the project. For example, you can clearly assign all components of the Revit category "mechanical equipment" to classes according to IFC 4.1 or IFC 2x3 and thus significantly improve the quality of your IFC export. However, your own classification systems are also possible.

Furthermore, this function offers the possibility to assign cost groups to components and to export them grouped. Classification schemes for IFC 4.1 and IFC 2x3 as well as for the cost groups according to DIN 276, ÖNORM B1801-1 and SN 506 511 (eBKP) are already supplied by liNear.

A simple and quick classification is possible via the illustrated dialog. A lot of time and effort is saved by the automated classification of network components in combination with the liNear network calculations. By pressing the proposal function (magic stick button), the program already suggests the appropriate classes, which you can accept but of course also assign manually.

The classification manager can be found in the liNear ribbon in the interoperability area.

21.2

When laying heating or cooling circuits, you now have the choice of whether the circuits are to be displayed in detail or in simplified form. In the simplified representation, a generic family without room-filling routing is used for each circle. This gives you the ability to specify the connections in rooms with multiple circuits and connect them to a manifold without having to worry about detailed routing of the supply pipes within the room. Using a single Revit family instead of individual routing can also help to improve the performance on large projects.

The panel heating / cooling control elements, including supply pipes and the assignment of circuits to distribution connections, can then be transferred to liNear Building using the Update function. During the transfer, the construction areas, the systems, the laying patterns and the installation distances are transferred. In the case of supply pipes that pass through several rooms, the room allocation of the supply pipes is also correctly taken into account for the purpose of heat balance. In later design phases with higher detail requirements (LOD), the simplified representation can be converted into a detailed circular representation at the push of a button.

21.2

You can now also use Revit groups in the potable water calculation. Particularly in projects with a high degree of prefabrication, Revit groups can show their advantages. By taking them correctly into account in the calculation, you can now specify dimensions and configurations of an entire group of components in order to use them several times in identical form. For this purpose, an option has been added to the configuration dialog. If this is active, the drawn dimensions within groups are taken over, fixed and no longer changed during the dimensioning. This is also taken into account during redimensioning by the command Adjust nominal diameters: the pipes within the groups remain unchanged in the model and the groups thus remain identical. If the option is inactive, the network is calculated and dimensioned as before.

21.2

A filter for displaying rooms has been added to the Zoning section. By entering a search term, only those rooms are displayed whose name contains this search term. This makes zoning based on room names much faster, especially in large projects. For example, if you filter by "Office", only rooms with "Office" in their name will appear in the tree view, which can then be selected contiguously and assigned to a zone. For rooms that have already been assigned to a zone, the zone is now additionally displayed behind the room name for information purposes.

The new filter allows you to quickly find or select rooms in the project, e.g. to check or adjust the zoning. After deleting the search term from the input field, all rooms are displayed again.

21.2

In the liNear template, a new label is now set by default for MEP spaces. In addition to name and number, this label contains the target temperatures taken over from liNear Building as well as the calculated heating and cooling loads. You can choose whether the data is displayed for heating, cooling or both. Prerequisite for the display of the data is the previous transfer of the values from liNear Building.

21.2

Any text parameters for room name or number can now be transferred to MEP spaces using the Data Transfer from Architecture Rooms function. You determine which values are to be used by specifying the parameter names in curly braces. Afterwards, these values are transferred from the associated architecture room or, in case of an IFC file, from the IfcSpaces into the room names and numbers of the MEP spaces.

21.2

The liNear Control Board now allows you to create your own disciplines by copying an existing one and creating or assigning the associated systems for pipes or ducts in the "System Classes" dialog. This allows disciplines to be customized to your needs and eliminates the misunderstanding use of existing system classes as "alias system class".

In addition, disciplines can now be easily disabled for display in the Control Board. This increases clarity when working in only a few disciplines. 

21.2

Within the workflow of Construction Design in the liNear Control Board you will now find a function for placing flange connections. You can position flanges at pipe ends, at pipe accessories or as pipe separations, whereby the dimension of the flanges is of course automatically adjusted to the nominal diameter of the pipes.

This significantly improves a key limitation of Revit when dealing with flanges in pipe systems.

21.2

Also in the workflow of Construction Design in the liNear Control Board, there is now a new function for assigning position numbers. Using this function, you can quickly and easily assign position numbers to each component for up to three different use cases. You can prefix and postfix the numbers as well as use sub-number ranges (such as 100.2 or 96.c).

The options in the dialog allow you, among other things, to influence the order of automatic number assignment and to specify whether identical components should also receive identical item numbers. Finally, you can use the Check button to identify which components are not yet positioned in the project.

21.2

Due to the logical assignment to the workflow Construction Design, the command for dividing pipes and ducts into section or delivery lengths is now centrally available there. As a result, this command has been removed from the design area of the individual disciplines.

21.2

The families for transition fittings from a rectangular to a rectangular, round or oval duct using the neutral liNear ducts have been revised. A minimum length based on a maximum angle is now considered for the transitions. The length of the transitions then results either from the minimum length or from the entered length (l) if this value is greater. Avoiding very short transitions with extreme angles leads to significantly lower pressure losses in your design.

21.2

The Adjust nominal diameters function can now be done on a section of a network, analogous to our solutions on AutoCAD. When you click on the function, you can select whether the adjustment should be applied to the entire calculated network or only to a selected part of it. Especially for very large projects, this also has a performance advantage, since you no longer have to redimension the entire network when considering only parts of it and work section by section.

21.2

Latest at the moment of construction design and the associated increase in LOD, the requirement arises to replace neutral components with real manufacturer components. To significantly speed up this process in Revit, there is now the Replace all function in the liNear CAD Browser.

After activating the command, you select a component in Revit and the program determines all components of the family in the model with the same dimension in order to replace them in one step with the selected component from the CAD Browser. Of course you still have the option of individual replacement via the Replace command.

21.2

The Place and Replace functions in the CAD Browser have been improved and now allow you to insert the selected part several times in the model without having to restart the command. Thus the command remains active and can be ended with the ESC-key after inserting the last part.

21.2

Especially in combination with ceiling heating or cooling systems, 6-way valves are increasingly used. These can now also be calculated within the pipe network calculation. With these valves, you build your systems exactly as in reality, and can then calculate both the heating side and the cooling side.

For this purpose, neutral and also manufacturer-specific 6-way valves are available. The desired valve data can be assigned to the components via the Valve preselection dialog. You can choose between valves with and without a flow control. So that the sections downstream of the 6-way valve can be detected and calculated by both disciplines, the system classes (Revit) or media (AutoCAD) heating/cooling supply water and heating/cooling return water have been added.

21.2

In response to many customer requests, the option of individual renaming has now been implemented for all components in pipe networks. This means that you can now assign your own descriptions to each component via the components dialog. These are then used both for the calculation dialog and in the parts lists. A reset button next to the input field can be used to reset the name to the original, automatically assigned one at any time.

21.2

For the calculation of simultaneity of fresh water and dwelling stations in the heating pipe network, the procedure according to VDI 2078 has been supplemented. This can be found in addition to all existing calculation procedures in the dialog Dwelling and decentralized fresh water stations.

21.2

Within the Assistant for Fresh Water and dwelling stations, the calculation of the tap rate based on DIN 4708 or VDI 6003 has been integrated in the Potable Water Requirements dialog.

This now gives you the opportunity to determine a standard-compliant tap rate for the selection of a suitable dwelling or fresh water station before designing the potable water network.

21.2

The calculation of the ejection times has been extended by the procedure according to VDI 6003. Here you define the required comfort level in the configuration and the program checks for each consumer, depending on its type (washbasin, shower, etc.), the compliance with the required temperature and time.

21.2

For the optimization of heating systems, the priority circuit for the heating of potable hot water tanks has now been implemented in Analyse Heating.

By using such a circuit, the heat supply to the radiators is "interrupted" during the heating phase of the hot water tank. The pipes from the boiler to the switching valve of the priority circuit are dimensioned for the respective larger mass flow (usually for the Potable water heating) instead of using the sum of both mass flows.

21.2

In the list of temporarily stored components, e.g. from the Trox Easy Product Finder or from the SCHAKO design program, individual entries can now be removed via the Delete button, e.g. to improve clarity.  

21.2

By definition, IFC files contain not only the definitions of all individual components but also information about the related systems.

Since the output of systems has led to problems during the IFC import of some external programs, you can now optionally deactivate them for the export.

Note: However, we still recommend the IFC export including the systems (IfcSystem) in order to be able to show and hide them with all their components in receiving platforms as well as to simplify navigation. For example, it is thus possible to view only the "supply air" within the IFC. Only in the case of a problem, deactivating would be a way to overcome deficits in the IFC import on the opposite side.

21.2

When drawing the supply pipes of panel heating systems, the function "End (+manifold port)" is now available in the context menu in addition to "End".

Analogous to the previous function, this command ends the supply pipes at the last selected point, but adds a "pipe extension" of the supply and return to the manifold.

Especially in case of complex pipe runs, this facilitates the pipe routing in the wall. Previously, only the last section was routed vertically upwards to the manifold. Now, for example, you can run supply pipes down from the ceiling to the side next to the manifold and have them connected directly below the manifold. The additional pipe length is of course also taken into account within the performance and pressure loss calculation.

21.2

The dynamic cooling load calculation according to VDI 2078 has been extended by the calculation of a year simulation. Using the test reference years of the German Weather Service or comparable sources, you can now determine the required heating and cooling loads for every hour of the year.

In the course of the extension, the entire program interface has been optimized to simplify e.g. the creation and management of profiles for temperatures, utilization, etc.. In addition, the positions and designations of individual interface elements have been optimized

21.2

Under the calculation configurations, the calculation according to the Swiss heating load standard SIA 384/2 is now also available.

21.2

You can now calculate the transmission heat losses of building components that neighbor on unheated rooms, in addition to the calculation by means of a correction factor or a fixed temperature, now also via a stationary heat balance to determine the resulting temperature.

For the calculation in liNear Building the unheated rooms have to be transferred during the building analyse. The then calculated temperature is displayed in the result window of the unheated room and transferred to the neighboring building components to calculate the transmission losses. This applies to the calculation according to DIN/TS 12831-1, EN 12831-1 as well as to the Swiss standard SIA384/2.

21.2

In most projects numerical values are used for room numbers. Therefore, in liNear Building the order in the building structure is done by default according to this room number.

In projects where also letters are used for room numbers (e.g. GF.010), these room numbers appear in the abbreviation field. In the program options you can now optionally activate the alphabetical sorting of this abbreviation.

21.2

Under the Help menu button, the Training Videos entry has been added. Clicking on the option will take you directly to the tutorial section on the liNear website.

As a customer you have access to all training videos here. For this your website account must be verified as a customer account. If you are not yet activated here, use the form on the tutorial website to request activation. For new accounts this request is optional within the registration. We will activate your account immediately after verification.

21.1

Besides the trades, you will also find the area of workflows within the disciplines in the liNear Control Board now. Functions that are independent of trades are provided here. In addition to the Void planning already integrated with Version 21.0, you will also find the new Pipeline corridor concept for the pre-dimensioning of equipment rooms and the generation of supply pipeline corridors in early design phases, and with fixations the first tools for Construction design. 

21.1

Integrated design means that even in the early design phases, all parties involved work together on the concept of the building. With our tools for the design, dimensioning and placement of equipment rooms and supply pipeline corridors, you have the possibility to optimize the installation of the designes building services in collaboration with other trades already in very early design phases. The resulting initial effort is more than compensated in subsequent design stage by reduced friction points and shortened revision planning.

21.1

New tools for the dimensioning and location of equipment rooms in the early design process are available. With the tools you can determine a realistic space requirement for the equipment rooms and coordinate this with other parties involved (e.g. the architect) in the early design stage. This enables active conflict avoidance instead of costly changes having to be made in the course of conflict resolution in the later design process. The space required by the equipment rooms of the individual trades can either be determined quickly and easily in accordance with the rules of VDI 2050 with just a few specifications or specified based on experience. The equipment rooms can then be placed in the model as Provision for Space (an element of the IFC 4.0 standard) and the space requirements can be compared with the available space in a conceptual architectural model. The export of the equipment rooms by means of IFC enables quick and easy coordination with the architects.

21.1

The pipes of the individual trades run from the equipment rooms to the consumers along pipeline corridors. With the pipeline corridor function, these can be constructed easily. Subsequently, the cross-sections are defined and assigned to the individual pipeline corridor sections. Adjust dimensions is a quick and easy way to adapt the space requirements of the pipeline corridors to the assigned cross-sections. Once the pipeline corridor concept has been coordinated with all parties involved using IFC, the pipelines can be generated automatically and used as the basis for further design phases.

21.1

Within the construction design, you can use the Fixation function to place brackets and various other fixings for pipes and ducts. The fixing elements can be placed individually, in line, suspended from ceilings, suspended on floors, or mounted to walls. The in-line placement mode allows the placement with a given distance between the elements. If the distribute symmetrically function is selected, the elements are distributed equally around the axis point of the selected area.

21.1

The Level of Geometry (LoG) is a model development level specified in the BIM Execution Plan (BEP). This is used to control the level of detail of the geometry in the model progress of the project. With the new View Manager in the liNear options you can freely configure the display of the components, i.e. you can define which display type should be used in which LoG. The presentation ranges from symbols or rough concept bodies to detailed presentations with manufacturer-specific characteristics.  This allows you to define the LoG according to the agreements made in the BEP for a specific project. It is also possible to define whether installation and operating spaces should be displayed within a LoG or not. If the respective family does not provide this information, you can define such subcategories in the Revit Family Editor with the help of the liNear LoG Assistant. Open the LoG-Assistant via the liNear Ribbon.

21.1

The Parameter Manager has been fundamentally revised. Now it is possible to use own parameters as input and output parameters for the pipe and duct network calculation. This allows linking several parameters to a single parameter of liNear. This is very useful for families from different sources that use parameters with different names for the same value. The order of the parameters in the dialog results in a prioritization for reading and writing. Especially in conjunction with bidirectional synchronization between liNear Building and Revit, the configuration of the prioritization when reading the parameters is decisive.

21.1

The new function allows exporting component and quantity lists from Revit in order to edit the changeable properties of the exported elements outside Revit. The lists can then be re-imported to transfer the changed properties into the model. In this way, parameters can be edited and enriched outside Revit, as well as information can be exported from the model using Excel. Exemplary is the transfer of parameters of a room book to MEP spaces.

21.1

In the options, you can now define to what extent the void proposal should be rounded up or down when generating. When creating void proposals, its dimensions are determined by means of an edge distance to the pipes. Depending on the dimensions, this is carried out to the millimeter. In practice, this is usually not necessary. This new function allows you now to define the desired precision.

21.1

As from now on, you can assign a standard-specific room type to MEP spaces, which is used in the heat load calculation and in the domestic ventilation in liNear Building. The room type set here in the liNear properties dialog is automatically transferred to liNear Building during building detection.

21.1

In the potable water calculation, flow dividers can now be calculated based on VDI 3805 data sets (e.g. of the manufacturer Kemper). As a result, the ring line is consistently dimensioned with the same nominal diameter. In addition to the pressure loss, the calculation also checks compliance with hygienic operation. The flow dividers are available in the preselection like all other valves.

21.1

In the duct network calculation, the dimensioning of the ducts can now be carried out not only based on the maximum velocities of connection and distribution pipes but also on the basis of maximum velocities, which are staggered into volume flow rate ranges. You can set these velocity limits manually. 

21.1

In the duct network calculation you can control the dimensioning of the air ducts even more precisely now. By fixing individual attributes, they are not automatically adjusted within your design, which is a great advantage especially when working in 3D. You can, for example, enable the dimensioning of the ducts and at the same time specify that the pre-selected setting of the device description (rectangular, round, oval) be not changed. You can selectively control the following attributes: Device description, Height, Width, Diameter, max. velocity and max. R-value. This is possible by object selection for the entire system, selected flow paths as well as individual sections.

21.1

With the liNear duct network calculation, you get a clear dialog for editing the rooms. By displaying the data in a tree structure, the required parameters for the calculation of the desired target value and the acoustics can be easily defined. The existing parameters, such as the dimensions, as well as the placed air diffusers are automatically read from the rooms contained in the model. These are clearly displayed per room. If outlets are not clearly assigned to a room, this can be corrected manually in the dialog now.

21.1

The IFC import has been extended by a variant that allows you to read in the IFC in such a way that the geometric presentation is optimized. Therefore, select the Import geometrically correct model option in the IFC Architecture Import.In this case, the architectural objects are not displayed as AutoCAD objects, but as solids, meshes and block references. This generates an optically correct model, which provides helpful details especially for the construction and can be used for further MEP design. For the building analysis and calculations based on it (e.g. heating and cooling load calculation) the import as architectural objects is necessary, as (so far) all necessary component information for thermal load calculations are contained only here.

21.1

With this version, the possibility of manually classifying components for IFC export is introduced. Use the keys IfcExportAs, IfcElementType and IfcElementName in the component data dialog to edit category, type and description of the component. These are then applied during IFC export. This is another important step to extend AutoCAD with liNear for participation in openBIM processes.

21.1

In the configuration of the labels from the network calculations, you can now include all available parameters in the label with one click. Click the column header on in the Configure Labeling Parameters dialog to activate all units of the parameters. Click again to deactivate all. Similarly, the decimal places can now be conveniently reset to the default value by clicking on the column header Dec.pl..

21.1

In the project, settings of liNear Building you can now define that several apartments are connected to each other in the consideration. With this function, apartments that are spread over several storeys can now be easily considered as one unit for the heat load calculation and domestic ventilation. Additionally, suggestions for predefined configurations of the building type, building unit and ventilation zone are now available. You can select these using the Examples button based on common types of buildings.

21.1

In addition to EN 12831-1 in combination with the German DIN/TS, you can now also perform the heat load calculation generally on EN 12831-1 (2017), so that a heat load calculation can be created for all European countries. Furthermore, the heat load calculation has been extended by the printout agreements and the option to increase the default values.

21.1

The window configuration in the dynamic cooling load can now be accessed directly at the project level and replaces the external shading. This allows all configurations to be defined at the beginning of the project and then assigned to the individual windows. External shading is still a part of the window configuration and can be set here.

21.0

With the liNear Installation Center, the installation of the liNear software, updates and manufacturer data sets is carried out centrally. All available installations are displayed, which you can select and then install together. With the manufacturer data sets, the program checks your already installed data sets at every start and offers you only the data sets that are suitable for you. These can then be downloaded in bundles and installed directly.  In the future, downloads will only be possible via the liNear Installation Center, so you do not have to download and install each data set individually from the website. To download the data sets, use your login from our website.

21.0

The Issues and Tasks section now allows you to resolve editing conflicts for both external BCF files and embedded topics in worksharing environments. For example, if the status of one or more Issues has been changed in two sources, a preview window opens where this conflict can be resolved.

21.0

The command Pipe offset in the liNear CAD Solutions for Revit can now also design offsets around pillars, joists and other architectural elements.

21.0

You can use the Legend function to create and customize a legend containing the components and system classes of individual views. This legend can then be placed on sheet views. The scale, level of detail and image style of the components in the legend are taken from the view from which it was created. A common legend can also be created on a sheet view with several views.

21.0

In the library tab, the mode Place on grid has been added. You are guided through the mode by a dialog. In the dialog you can arrange the components in rows and columns in space. Alternatively, you can use the Fixed grid function, e.g. for an Odenwald ceiling, and position the components centered within the grid. 

You can also use the new button with the pipette to select components from the drawing and use them for placement and replacement.

21.0

The pressure loss calculation in the gas pipe network has been extended by the Renouard method. The method can be selected for dimensioning according to general procedures.

21.0

The slanted walls newly introduced in Revit 2021 are now also taken into account when transferring the building data to liNear Building.

21.0

The Search & Replace dialog has been extended. The search filters for room components have been extended by the option Room name. The filter allows to change component data of components in similarly named rooms. In addition, the filtered components or rooms can be deleted from the project using the Delete elements button.

21.1
