Chapter 8: Interoperability: Working Multiplatform

Use imported 2D CAD data. CAD data can be integrated into your Revit project in a number of ways: as plans of existing conditions, as fixture layouts from consultants, or as standard details from your company's library.

Master It How can CAD details be used in Revit?

Solution Create a new drafting view for a single detail. From the Insert tab, choose Link CAD and select a DWG detail file. During linking, set the colors to Black and White. Make sure the scale of the drafting view matches the notation scale of the CAD detail. Use the Query tool to turn off unwanted layers within the linked file.

Export 2D CAD data. The ability to deliver quality 2D information to other constituents involved in your project is as important as importing it into Revit. Appropriately formatted views, standardized layer templates, and proper coordinate settings will result in happy team members and a smooth coordination process.

Master It Does Revit comply with the National CAD Standard?

Solution You have the ability to map Revit model categories to standardized layers in the Export Layers dialog box. Access this tool by clicking Application menu and selecting Export Options Export Layers DWG/DXF. Load industry standard layer conventions using the Standard button.

Use imported 3D model data. Model data generated outside of Revit can be integrated into your projects as whole building systems, massing studies, or unique components.

Master It How can a building's structural model created with Bentley Structure be integrated into Revit?

Solution Create a structural framing family into which the DGN model will be inserted. When the family is finished, the DGN geometry will be displayed as any other Revit structural framing component.

Export 3D model data. Your modeled elements don't have to remain in the Revit environment forever. Data can be exported to 3ds Max, Google SketchUp, AutoCAD MEP, and more.

Master It How can I coordinate my architectural Revit model with an engineer using AutoCAD MEP?

Solution The engineer will likely require one DWG model per level for efficient coordination. Create duplicate floor plans for exporting and adjust the View Range settings for Top to Level Above, Offset: 0 and Bottom to Associated Level, Offset: 0. Create duplicate 3D views for each level, right-click the ViewCube, choose Orient To View Floor Plans, and find the corresponding floor plans. These 3D views can be batch-exported to DWG format and referenced by the MEP engineer in her designs.

Work with IFC imports and exports. Industry Foundation Classes (IFC) is a vendor-neutral model format designed to support interoperability in the AEC industry. It is widely used by some major BIM platforms available around the world.

Master It How is an IFC model integrated into Revit for coordination?

Solution You can open an IFC file by clicking the Application menu and selecting Open IFC. Once open, the data can be saved as an RVT Revit project file and linked into another Revit file for continued coordination.
