Thank you all for the nice words! :slight_smile:

With regards to the question above, there are two main ways to create NURBS geometry on 3d scan data in Rhino without plug-in such like Mesh2Surface:

  1. Use snap to draw curves with the ! _InterpCrv command directly on the point cloud, then use some of the surfacing tools to build the NURBS patches.

  2. Place a surface (with 4-6 control points in each direction) relatively oriented towards the normal of the mesh surface, then show its control points, select them all and run the ! _Pull command and select the scan data as the target. Rhino will pull the surface quite accurately on the 3d mesh, though there may be a slight deviation (after all, it’s the control points that are pulled, not the surface itself) and you may need to slightly adjust the control points along their normal direction with the “MoveUVN” tool to make the surface exactly align to the point cloud. Sadly, there is still no “Pull surface on mesh” tool in Rhino, but this little trick does the job in most cases.

Here is a simple video tutorial that I just made to show the 2nd approach, though I used “Offset surface” instead of “MoveUVN” to raise the pulled surface:
