Maya has a tool called Slide Edge which allows you to select an edge loop or edge and slide it along a surface without changing the silhouette. Max has Constrain by edge/face/normal, which works the same for single edges, but doesn't really work if you have an edge loop on complex geometry, like an edge loop around the…
Select the edges you want to connect, that will bridge the edge(s) you want to create. Use the "Connect" tool dialog box. Adjust the Slide amount. The added edge won't affect the silhouette of the object.
Sorry, I tried to make it clear that edge constraint doesn't work for complex edge loops. I'm trying to see if there is anything more advanced, either within max or by script.
If you try to move a large selection of edges with constraints, yes, they can occasionally go haywire with multiple edges. Normally when doing HP modeling if I just can't get a large selection of edge loops to go correctly, I will simply use the constraints and move a handful of the verts at a time constrained to edges. As…
Well the primary reason is that I only want to slide part of the edge loop. For example, in this instance, I want to select the red part of the edge loop and slide it closer to the next loop so that there is a consistent gap between them for when it gets turbosmoothed. Edge constrain doesn't work in this situation because…
That's an interesting script. The fact that you have to select the perpendicular edge loops is a bit limiting, and means you are always affecting 2 edge loops instead of one, but I can definitely see the uses. It doesn't entirely solve my issue for all circumstances, but it works for some of them, and if no other solution…
Predator: as you're finding out, people can be quite hard to talk to when they've decided you don't need something, haha. I used Slide in Silo all the time, and it's quite lovely. For most purposes edge-constraints work well for me, though.
