STL Steel shapes (Free)

This is great LISP utility - not just a library of profiles but a real application to use inside AutoCAD or others "like AutoCAD" systems. It has a graphical user interface with button selections to get what you need whether it is an end view, top or side view, or a 3D solid. All the dimensions are there including the small radii edges. Once you have made your selection you are given either a standard ACAD solid (not and ARX entity) or a simple 2D drawing. The end views are closed polylines which you can extrude, if needed.
