1. Open the CAD file that you hope to import in REVIT. Be certain that the layers you want to see are turned on. If they are off they will not be visible when the file is linked. Save file. 2. Switch to REVIT. In the “Project Browser” menu select the site view under the floor plan option. We work be working in this view for the remainder of the process. 4. The “Insert” menu will have options to “link CAD” and “Import CAD.” While either will bring the CAD file into REVIT “Import CAD” is the option we will chose. Left click on “Import CAD.” 3. Left click on the “Insert” tab in the Menu. Creating Topography in REVIT from an AutoCAD file. ABSTRACT: Map a ground plane in 2-dimensions in AutoCAD and import file directly into REVIT then transition 2-dimensional ground plane into 3-dimensional topography. Explanation also applies to editing existing topography.
