Snaps don't work on Sweep1 objects?

Rhino
1

I made this object edge with a sweep1. I’m trying to move it from the mid point, but the snaps don’t work. The only snap I get is at the point where the sweep profile began. How do I get it to snap to the other snaps? Is there a command to make seams at quads etc.?

Hi @CalypsoArt
You are looking for DivideAlongCreases. Also, I think there might be a switch when doing sweeps that allow you to split at tangents (but not sure and not at my PC right now).
HTH, Jakob

Edit: And since your current seam is on the flat side, maybe run MergeAllFaces (or whatever it’s called) to make that side a single surface after dividing.
