The ability to browse drawing geometry in the Open Drawing dialog box would be very helpful. Solid modeling Solid Master supports a standard set of base, boss, and cut features that you extrude, revolve, sweep, and loft. You apply these features using one or more sketches that you created previously. To perform extrusions, you enter distances, select extents, and employ the typical through-all modifier for cuts and Boolean intersections. Revolved features support rotation angle only.
Sweeps do allow a sketch to rotate as it moves along the sweep path.
Lofts provide control for start and end tangent magnitudes. Other features include draft, shell, constant and variable fillets, chamfers, linear and circular arrays, and thin walls. Use the Make Simple Surfaces and Make Solid modifiers to construct base solids from wire frame geometry. You can cut, copy, and paste features and solids to and from the clipboard. At any time you can query properties such as surface area, solid volume, and center of gravity.
