Hi Tom! Thanks for your reply & the welcome. The image you’ve posted looks like exactly what I’m trying to do, but I’m not using a mesh surface, I’m using a nubs surface as this needs to be exported to solid works for further development. I’ve attached my file (hopefully) so you can see what I’m working with. There is a failed attempt still in there to show what’s wrong, & the base surface, geometry, & target surface in the middle.
