LINEAR Solutions V25.2

The new IDS import functionality significantly streamlines the implementation of Employer Information Requirements (EIR) and BIM Execution Plan (BEP) specifications by integrating standardized requirements directly into your Revit model. It creates a direct link between model-neutral requirements and practical Revit model implementation – reducing coordination effort, improving data quality, and supporting compliant, verifiable design in line with BIM processes.

  • Direct import of IDS files (based on IFC4):
    Model-specific requirements for properties, structure, and content are automatically imported, including assignment to appropriate element classes and property sets.
  • Automatic validation in the model: Mandatory fields and defined input rules are checked during import:
    • Missing mandatory parameters are highlighted in red.
    • Violations of value ranges or formatting rules are marked accordingly.

Early quality assurance: Visual feedback allows requirements to be checked and fulfilled during modeling. A significant part of the model check is thus integrated into the design process.

DE_Raumbuch_4.png

LINEAR Solutions V25.2

In early design stages, a complete CAD model is often unavailable – yet initial designs and calculations are already needed. With the new Room Book Synchronization, you can start confidently without a model and integrate your data seamlessly as the project progresses. This feature provides a continuous data foundation across all project phases – from concept to construction design – enabling a model-independent workflow early on while ensuring consistency in later BIM stages.

Import room book data from Excel: Capture building info like room names, numbers, temperatures, loads, or number of people directly from Excel. The data is immediately available in LINEAR Building – independently of a CAD model.

Early use for concept design and dimensioning: Use imported room parameters right away for preliminary heating/cooling load calculations or system concepts – without waiting for a full model.

Sync with CAD model as project evolves: When a detailed model becomes available, integrate it via the usual building synchronisation process. Rooms with matching names/numbers are automatically linked – including parameter comparison based on your sync settings.

Full control over data flow: Configure which parameters from the room book are imported, retained, or updated – bidirectionally and flexibly.

LINEAR Solutions V25.2

With version 25.2, the LINEAR Properties dialog becomes the central hub for editing all component and room parameters – efficient, clear, and model-wide. This speeds up the editing of large models, reduces error sources, and facilitates consistent data management.

  • Central editing of all parameters: All inputs from previous component and room dialogs are now available as editable LINEAR parameters in the Properties window – no need to switch between dialogs.
  • Easy multi-editing: Select multiple components or rooms and edit shared parameters in a single step. Only parameters available for all selected elements are displayed – for maximum clarity.
  • Automatic inclusion in network calculations: All changes are automatically detected and processed in the next pipe or duct network calculation – with no extra effort.

Typical use cases:

  • Standardizing pipe diameters, insulation, or valve settings across networks
  • Adjusting pipe types for multiple sections simultaneously
  • Central modification of room temperatures or usage types
