The Drawing Compare.dwg toolbar is designed to detect changes in different versions of drawings.

The comparison process determines objects that were changed, added or removed.

There is a number of limitations to using the Drawing Compare .dwg function:

·         The function works only in the model space.

·         Only .dwg files are supported.

·         The following types of objects are not supported: OLE objects, cameras, geographic data, GIS objects from Map 3D, underlays (not dwg), images, coordination models, and point clouds.

·         Changes of properties By Block and By Layer are not detected in nested blocks.
