Clean up mesh generated from overlapping curves Suppose I have draw overlapping curves in order to simulate branches. How can I clean up the mesh around the branches? Are there better techniques for drawing branched curves that also supports tampering and bevel effects?
Being in face selection mode select the trunk with L, press Space and type Intersect. Unselect it, then select a branch and hide it (H). Delete all the faces inside the intersection edge, unhide the branch (Alt+H) then join verices to create a clean topology. Then remove the rest of the branch's vertices. Finally remove doubles (W-->Remove Doubles).
