We installed and started using Mindesk VR for Rhino3d with Geometer. It seems to work great for our purposes, fixed dimensions and ease of module movement, alignment and general workflow.
Things like moving assemblies in Gravity Sketch were difficult or impossible and we ran into scaling and alignment issues. Mindesk is planning on releasing a Solidworks variant soon so we will look into that as well.
This is a first time user with minimal guidance.
The results are promising and we will continue to use Mindesk for form exploration. That it updates an active Rhino file is an invaluable feature. Moving forward we need to ensure that we can easily communicate a final design in multiple formats as well.
