For imported DWG and DXF files, you can specify the units of measure for the imported geometry, and define a scale factor to achieve the appropriate scale for the Revit project.
- Select the imported CAD file and click Modify | <File Name> tab
Properties panel
(Type Properties).
Note: SAT and 3DM files can't be scaled. - In the Type Properties dialog, modify Import Units or Scale Factor.
If you change the import units, the scale factor automatically updates. See Import and Link Options.
Note: If no values display for these parameters, you must reload the link or re-import the file. - Click OK.
