Autodesk DWG is a proprietary 3D geometry format native to Autodesk AutoCAD. Although it doesn't have modern material support, it is widely used in the BIM and CAD industries.
Note:The Autodesk DWG importer only imports 3D aspects of the file. It silently drops all 2D elements. In Autodesk AutoCAD, you can convert unsupported objects (such as polylines) using one of the following commands: AECTOACAD, CONVTOMESH, CONVTOSOLID, or CONVTOSURFACE.
For DWG import, the following options are available:
Click Browse to open a file dialog box and select a .dwg file to import.
Import as static model
When checked, the file is imported as is and cannot be modified by CGA rules. Otherwise, start shapes are created from the provided (if available, textured) polygons and are ready to be used with CGA rules.
Align to terrain
When checked, the geometry automatically aligns to the terrain.
Scale is the size factor applied to the imported object.
Offset adds the specified offset to the imported object:
