The ability or flexibility for quick edits of layouts/photoshop files when using with Revit MEP models are great! No need use many apps like Sketchup if you want working quickly without any glitches from 3D modeling softwareRevistMEP Modeling is good but still needs some tweaking compared by others CAD packages (Solidworks etc.).The overall service provided was also exceptional very helpful whenever we had issues during our project implementation processWe were part an architectural design team that used different types modelling tools such. The ease of use is amazing! I have never seen such an easy system for creating promotional items like t shirts or bags with custom designs that are attractive enough so customers will want them!! There's nothing about this software i dislike but everything else (including it being free) makes me love using RPAC even more than before. This program has helped us create many unique promo gifts at no cost which we can then charge our clients when they sell these goods through another channel/platform.
