How to create fastener vectors without geometry.
Hi everyone! This should be a simple question: how can I create fastener vectors without geometry? My component is a curved panel with holes for fasteners. I’ve already inserted RBE2 elements with a central node at each hole. Now I want to create a line/vector/coordinate system normal to the surface at each hole. I found the *geomvectorcreate command, but it requires a surface, which I don’t have. Eventually, I want to place CBUSH elements using two nodes aligned along the surface normal at each hole location. Is it possible to extract the normal vector based on the mesh or surrounding nodes? Of course, I am looking for tcl/python solution :)
Thank you!

Perhaps you can use Connectors directly? they should create the system in the right orientation
