I like how easy it was to learn because there are many tutorials you can find online which make learning very simple. The program does not have all the functions we need for our job but with some time spent in training and using this product, those features will be added as well! There's nothing really i dislike about this product at this point. It has helped us do what we were looking for. We use this program daily and have been able to help build different projects from small scale models to large industrial products.
