The full version of Conveyor now installs plugins for both Rhino 6 and Rhino 7 WIP. The Revit addin also supports Rhino 6 and 7 3DM files! Existing customers can pull down the update. New purchases will come with these updates.
You can see the release notes here.
NOTE: It seems one Rhino 7 3dm limitation at the moment is that OpenNURBS libraries do not yet provide the ability to access a SubD meshes for rendering and conversion. If you are looking to convert the SubD to Revit using Conveyor, you will need to first convert the object to a Mesh or standard Brep within Rhino before importing… more to come.
