I’m a retired engineer and new to 3D design software, I have been using Shapr3D for about a year. I design useful things for around the home and also create models for use by n-scale railroad enthusiasts. Lately I have been working on a project for use in sport fishing. I can’t say much more about it other than it has a patent pending and will be launched soon. I like Shapr3D because it is convenient to sketch on an iPad. It lacks functionality such as found in Fusion 360 so I have to design some things there and then try to incorporate them into Shapr.
