In this video I walk through a sample 3D part. I use a sweep surface based on wire frame, and planar surface based on surface edges. Working with surface edges for design in a new feature in the V27. Once we model the part I lay down a roughing and Z level finish tool path. In the V27 Mill Pro we've added a Zig Zag option allowing the tool to cut back and forth following a profile, almost like a flow line. Once simulated, we go back to the model make some changes and update the tool path. Take a look!
