Pros : Feature-rich, accurate, scalable, great glass library, excellent printer driver, nice lamp wizard... lots of good menus and features. It is CAD -customized for glass design work.
Cons : Users unfamiliar with a little basic CAD can be initially frustrated.
Other Thoughts : Even if all you are making are crosses and red-green tree ornaments, this product can make you a better glass artist. It is the go-to tool for glass design. Classical stained glass, fused glass, even lamps. I have ported the SW through several operating systems and computers, and found the support to be appropriate. The company's level of piracy protection is warranted. It is valuable.
