If you take into consideration that Shapr3D is CAD-Program based on a (Para)-SOLID-Kernel, it is way less strange that it is not capable of editing MESH-Files. (Shapr3D is not meant for Sculpting, at least in my oppinion.)
BUT (and this is something I find extraordinary): You can in fact import the STL-File into Shapr, Add geometry with Shapr-features and unite the bodies, or subtract them! That way you can make a mould of a STL-file, if you want.
Lets say you would like to do similar on SolidWorks for instance:
- You need a Professional or Premium-License that includes the „ScanTo3D“-Addin, costing 8500€
- you need to turn the mesh-body into a solid in order to use SolidWorks-features on it.
I have to say: I am quiet happy with how Shapr3D handles STL-files - and that it does at all!
