Hi everybody, I started using this software 2 months ago. It is an amazing software. I discovered generate roof plug-in two days ago. It is an amazing tool. It served me from making a lot of calculations when creating roof in 3d. Dorin is a genius, I admire his ingenuity. There are some difficulties I experienced especially in designs that combines gable and hipped roof. I will discuss the issue in detail with Dorin. Nevertheless, the discovery of this plug-in is remarkable feat of ingenuity.
