It is very user friendly, it helps in designing with ease which saves lots of time and effort. The software also allows for multiple users so everyone can work independently from each other while producing their own designs without any hindrance or interference. I have found nothing that has been dislike about this product thus far. To be honest, this program really helped me out when working on creating my drawings for my school projects. This was quite helpful since drawing required skill and patience. And by using this software i made sure that everything drawn had no errors and could not possibly get lost or misplaced later.
