I know that SOLIDWORKS files can be converted and used in composer, but is there any way to derive the solid parts from the .smg file?
by converting SolidWorks to Composer (smg) the geometry becomes simplified. All logic is deleted.
here is no way back to SolidWorks.
Its possible to save the files as 3dxml, u3d (Adobe Acrobat), STL, obj, ... but i dont know any converter back. All those formats are tesselated. If you find a possibility to convert them to STEP the quality will be very bad.
