The ease of use, speed to get results from my prototype/mockup design in under an hour! I am able create complex 3D models quickly with very little effort compared other programs that require more time than money for me as designer or developer (ease-of development). There is also no learning curve since it's so easy once you understand how things work - if there was any downside at all besides price point would be better documentation about some features like exporting STLs etc which are not well explained within their help section but can easily find online elsewhere through trial & error process instead.. It only took around 30 minutes before i had finished creating this model using Autodesk Revit API integration into rapidgen software platform.
