I have a complicated multibody part which begins with an imported surface. The surface does not include straight edges or constant radius arcs. It does have a few vertices.
I want to replace this imported surface with another imported surface with a slightly different shape. Considering that all subsequent features will be formed in the same way, I would hope that there would be a way to replace the surface in this first step and update references when necessary. I have been so far unsuccessful with the replace face tool. Is there a secret to using this tool, or another method I should be using? Or is this not possible, and I should simply repeat the entire process?
