Currently Rihno is the best software for me, is it possible I use VR sketch in Rihno? Or are there other extensions suits Rihno?
VR Sketch is unlikely to support more than SketchUp soon. Other software like Rhino focus on a more structured approach, which would work less well with VR Sketch’s approach of freely editing in VR. How to integrate with the workflow of these other tools? We did not spend much time on this problem, but it is an open question.
If you’re interested mostly in the “viewing” part, though, there are existing tools: Enscape is a well-known example, but there are many of them.
