What do you like best?
Most of all there is a 100% free version to you learn and use. It also uses .dwg extension which a lot of the other CAD software does not.
What do you dislike?
As in most cases trying learn a new CAD software has a curve and this one is no different. but over all not that bad to learn since a lot of the commands are the same as AutoCAD, so that makes it a little easier.
What problems are you solving with the product? What benefits have you realized?
Have no got to that point in solving issues or being proficient, still learning, but to be truthful, it realy hard to break away from AutoCAD. The only benefit at this time is that the version I am runing is free and this maybe the issues in breaking beyond and escaping from the cluches of AutoCAD.
