If you’re a Rhino user, you’ll notice Shapr3D shares some similarities with Rhino. However, there’s one big difference: Rhino is a surface modeling tool, and Shapr3D is a solid modeling tool.
Shapr3D’s underlying engine, Parasolid, makes solid modeling operations in the app robust yet undemanding. You’ll notice that the app doesn’t require any labor-intensive, manual post-processing of your geometry. And when you want to modify something, like creating blends or shelling bodies, it’s much easier to do it in Shapr3D.
Using Shapr3D as an extension to your existing workflow with Rhino can only help you. As a matter of fact, Shapr3D can completely replace some, or all, of your other modeling tools. You can painlessly move models and sketches between the two tools if you export and import them in STEP and X_T files.
