When opening a CAD file, file begins to load (slowly), but abruptly stops and the following error message appears: “Not enough memory available on device. Model is partially rendered. Try selecting fewer layers and reload the file again.”

Selecting fewer layers to decrease file size may not resolve the problem.

File needs to be EXPORTED from CAD as a DWG, not simply SAVED.

Exporting process will “flatten” many of the entities and reduce the file size and complexity greatly.

Issue has been seen with DWGs saved via Revit and Autodesk Architect.
