Great program for 2D design applications!
For estimating and drafting/design, it is a great tool! I would not recommend it if you are looking for 3D modeling software.
It has made the process of estimating so much easier. When I use it in conjunction with my CAM nesting software and other estimating tools, it takes the work out of estimating a great number of RFQs.
I like how easy it is to make flat pattern parts using this program. I also like how it allows me to import/insert drawings or images into the template and trace them out. It is a great way to start your drafting/design career and it can be used in so many different applications.
It is not ideal for 3D modeling and does not simplify the creation of formed parts.
