Details on"Classification Tables"
Information on the Classification table dialog.
Lists the components of the current selection or the section of the model currently displayed and allows the assignment of values to a classification parameter.
You are here:
System, scheme
Drop-down list for selecting the classification systems. The systems MepClasses, Industry Foundation Classes and Cost Groups are pre-installed and are always available in the list. You can choose from different schemes for the Industry Foundation Classes and Costs Groups systems. You can also create custom systems.
LINEAR
This classification system allows you to classify components according to their calculation type for LINEAR pipe or duct network calculations. The classification is based on the cross-disciplinary three-step MepClasses classification system, which was specially developed for the building technology sector. Components that are used in multiple disciplines only need to be classified once in order to be correctly included in the calculations for all disciplines.
The top level of the system is the Domain, which represents the different areas of building technology, e.g. Heating/Cooling or Fresh Water/Drainage.
Within the domain, a division is made according to the functions of the components (Function). This level combines objects that have comparable functions, such as expansion vessels and backflow preventers, which fulfill safety functions in the Heating/Cooling domain and are grouped under the Safety function.
The third level of organization is the Class of components. The object classes, which represent specific characteristics of the individual functions, are defined at this level. The Safety function, for example, includes classes such as Backflow Preventers, Expansion Vessels and Water Shortage Safety Devices. Based on the selection of the class, the calculation types and thus the functions of the components in the network and the technical data used in the calculation are defined. Depending on the class, further variants of the classes may be offered, which differ for example in terms of slightly different technical data and other designations for the output in the parts list.
Industry Foundation Classes
This classification system allows you to classify component types in order to prepare them for IFC export or to make a finer differentiation of existing component types. All classifications are performed in the type parameter mode - all copies of a component type in the model will have the assigned classification. For this reason, the components are sorted by category. You can choose between the schemes IFC 4.1 and IFC 2x3 TC1.
Cost groups
In this classification system, you can use the parameters of the component copies to assign a cost group to individual components. The components are sorted by system in the view. You can choose between the schemes DIN 276-1 (2018-12), DIN 276 (2018-12), SN 506 511 (2012-de), SN 506 511 (2020-de) and ÖNORM B 1801-1 (2021-02).
Hide classified
Enabled: Already classified components are not displayed any more.
Disabled: All components of the selection or the displayed model section are displayed.
Make Suggestions
Generates classification suggestions based on the internal calculation types. Here, all components of a calculation type are assigned the same stored value. Suggestions are always generated for all elements that have a calculation type assigned to them with associated classification parameters. Before you write classifications to the model which were automatically proposed, it is important to always check the classifications for correctness. For classification systems without allocation tables (mapping.xlsx), the button is hidden.
Table of model elements
By selecting the desired lines and opening the context menu with a right mouse-click, you can edit multiple entries at once. Via the context menu you can open the Select classification dialog, where you can select parameters from the catalog of the classification system or reset the selection to the default setting.
Hold the cursor over the line of a component to display a preview and the classification of the component.
| Column | Description |
|---|---|
| Type | Shows the component type of a component. |
| Quantity (for classification with parameter of copy) | Number of copies of the respective part in the current view or selection. |
| Category (for classification with parameter of copy) | Revit category of the selected component. |
| Calculation type | Classification of component in the LINEAR pipe network calculation. This internal allocation is the basis for generating a proposal. The allocation of calculation types to components is stored in the mapping file and can be adapted there. |
| Classification | Displays the values of the classification parameter, which are written to the component or component type after the dialog is confirmed. You can enter the value either manually or select it from the catalog of the classification system in the Select classification dialog. Assigned values are displayed in bold. Parameters in angle brackets are written to the component, as long as no other parameter is assigned. Should an assigned parameter not match the catalog of the classification scheme, this will be displayed by an exclamation mark in a red triangle. |
Opens the Select classification dialog, where you can select parameters from the catalog of the classification system. The currently selected parameter is displayed in the footer of the dialog.
Clicking OK closes the dialog and the corresponding parameters are written to all selected types or copies.
