View Full Version : Flip Triangle Edge for all quads

I have sort of an oddball problem, and can't find a solution. Basically I have a big mesh, made up of perfect quads, but they're all triangulated in the wrong direction (it's long to explain, but basically it needs to match another mesh as closely as possible). I can use the "Flip Triangle Edge" command to flip them individually, or all that I select, but I need to do this with about 20 meshes, each 150k-250k quads each, so manually performing this is labor prohibitive.

So, any suggestions for how to process the mesh to do this, or perhaps how to select every 45 degree angled edge? I'm guessing that maybe this should go in the Mel forum, but I'm basically useless with Mel, so I figured I'd try posting in general.

Thanks.

Maybe try selection constraints, Edit Polygons>Selection>Selection Constraints. The angle or length option might work.

Length pretty much did it. I bet with some angle tweaking I'll make it perfect. Thanks for the advice.
