Hello Everybody, I had a question about creation of solids. I have recieved a .dwg file, except all the parts are surfaces instead of solids. I am accustomed to working with solids in Mechanical Desktop. Is there any way to convert these surfaces to solids? Some of them are fairly complex in shape and would be very difficult and time-consuming to create on my own (as solids) from scratch. Any ideas? Thanks alot. -Ryan
