Solid objects created using such commands as Add Solid, Subtract Solid, Create Subdivision Primitive, and tools such as Fillet Edge, Chamfer Edge, Shell Solid, and Edit Subdivision, contain a history composed of the original elements used to make the new object. This also includes any editing performed with other solids operations. The Convert to Generic Solids command removes this history from the solid objects, reducing the file size (though the object is no longer editable).
For example, use this command on a copy of the final drawing to reduce file size when sending a file to a print bureau.
To convert an object into a generic solid:
Select the solid object to convert.
Select Modify > Convert > Convert to Generic Solids.
A warning dialog box opens. Click OK to convert the object.
The object is converted.
If objects are selected that cannot be converted, a dialog box opens stating that these objects have been deselected.
