Hey guys  
I’m making a vehicle in fusion and gravity sketch, ( as Shapr3D doesn’t support 3D splines/sketching, so doing patches outside). I’ll do all the details in shapr after

If I import this into shapr can I edit the surfaces?, bevel/chamfer/cut/union etc?.

Tried before and it wouldn’t work. Maybe if the shape is transformed into a solid and closed fully it would work? Any format best suited for editing patches/surfaces?

Hello, please make sure that the model is a solid body (even if it is a thin one). If you can stay within the standard CAD formats like STEP or IGES (X\_T if possible) and the model is a solid body, it will be possible to edit it in Shapr3D.
