ARCHICAD offers a number of visualization tools that make it easy to find and view the imported content within ARCHICAD, and, if needed, to differentiate it from the architectural model.
Note: You can set ARCHICAD to do this automatically as part of the merge process, using the appropriate control of IFC Translation Setup.
In 3D Views, you can use layer settings to display imported structural and mechanical elements differently from architectural elements. For example, set the 3D View Display mode of architectural layers to Wireframe, while applying Shading mode for all imported element layers.
ARCHICAD views can also be used to differentiate elements of different disciplines. For example, create some views showing architectural elements, and other views that show the structural/mechanical elements only.
If you activate an architectural view, you can then use the Trace & Reference feature to view a structural/mechanical view at the same time – differentiated by highlighting or colors, or splitting the views apart on screen.
For details on the Trace & Reference function see Virtual Trace: Using References to Edit and Compare Model Views and Drawings.
