It is a great 3d modeling package. It also has stress analysis add ons for it. Takes abit getting used to as it is a feature base cad rather than absolute draw like autocad. In solidworks you make the shape and then constrain it to create what you want.Makes nice 3d models.Once you have a shape eg a cube, then by changing restraints you can make it a rectangular box, without having to redraw the entire model.
I like it. Neil
