The most important thing that i like about it is its accuracy in terms of dimensions which makes product development very easy and fast as compared to other 3d cad tools available out there. I think this tool needs to be improved further so that some more features can be added to make it better than others. Nothing major but just an observation would do great. It's a good option when you have limited resources or don't need a high end solution like AutoCAD etc and still want something similar. We are using this program for designing parts like housings and then converting those designs into moulds by generating patterns from them.
