ArcGIS Pro reads CAD files as CAD feature datasets that contain read-only CAD feature classes. The following table identifies the supported CAD entities from AutoCAD and MicroStation and the corresponding ArcGIS feature class geometry types.
Note:
Content stored in AutoCAD paper space is not translated, and it is not viewable in ArcGIS Pro.
