Blender runs on Linux perfectly.
My Bricscad runs on Linux OK (As OK as on Mac)
My Modo runs on Linux OK
(Yes it is nearly dead, but still an option as it has great workflows)
So, has anyone already asked for a Modo Connector ?
Looks like you are the first one to ask Modo Connector is not on our roadmap but we continue to improve the Blender Connector which should help with your 3D visualisation workflows.
