I am having issues exporting .DWG or .DXFs that have multibody parts in them. Mainly the isometric views disappear. I've tried changing to high quality views.it says there was an error creating the precise geometry for following drawings. I tried healing surfaces but there are too many in the mutlibodies. Tried all options in DXF and DWG. Turing views to wireframe works, but is no use at all.
