Can AutoCAD users without AutoSolids access AutoSolids models?
Absolutely. When AutoSolids is not present, AutoCAD immediately recognizes any AutoSolids model as a native AutoCAD solid. Any command that can be used on a native AutoCAD solid(union, subtract, solprof, section, etc.) will operate exactly the same with an AutoSolids model. Be advised, however, that changes made to the model while outside of AutoSolids will not be editable should the model be brought back into AutoSolids.
