FeatureCAM supports the import of the following .dwg and .dxf entities. .dxf files have both ASCII and binary forms, .dwg files have only binary form.

AutoCAD files can contain two different spaces, model space and paper space. Model space is where you draw up geometry, 3D solids, and so on. Paper space is where multiple views of the model are displayed. Most AutoCAD files have only model space. FeatureCAM can import dimensions in both model space and paper space.
AutoCAD dimensions are imported as FeatureCAM dimensions. That means that you can modify the color of the dimension, easily delete the entire dimension or use the Show or Hide pull-out menus to toggle the display of dimensions.
See Simplifying 3D AutoCAD data for 2D import for more details.
You can import ACIS solids from DWG files, such as 3DSOLID, REGION and BODY entities, by using the FeatureCAM native import.
When you import a DWG that contains solid entities, the AutoCAD Import Method dialog is displayed.
Select whether to import using Exchange or the FeatureCAM native import. The FeatureCAM native import is faster, and you can import solid entities as solids in FeatureCAM. Solids are imported as collections of surfaces when using Exchange.
