Hi!
I’m working on this model and I need to create a plane that closes the base of the mesh and one that closes the semicircle (the smallest one). I need it all parameterized and “linked” and therefore I can’t work in Rhino. I’ve tried working with intersection points between the mesh and a plane, but haven’t had good results. I already have both the surfaces I need, but they don’t fit with the mesh contour. s there a method to reshape the surfaces i have already created? If not, how can I get the result I need?
Thank you for the help
