I am wanting to use the centerline of some imported geometry (simple constant circular sweep) to use as a base to start some surfacing I need to fit onto the imported model. Does anyone know if Rhino 6 has a function to do this?.. Maybe someone knows how to write a script for it?.. I can extract the wireframe mesh, but there is no centerline!!
It would be a wonderfully helpful addition to be able to do this with imported geometry, and give a very useful way to rapidly and accurately integrate with new geometry made in Rhino.
