Question

How do I set all display edges in a model to hard (in Maya 2017)?

I found a MEL script in a different post that lets you select all hard edges

(this one: polySelectConstraint -m 3 -t 0x8000 -sm 1;),

but I want to turn all display edges to hard, not just select them. I want to do this because I didn't build my model out of primitives and it's overly complex, (importing from SketchUp). The only way I can think to do this is individually select each and every mesh component and set it manually. But I feel there must be a MEL script that might do the trick, does anyone know of one?

Answer 1

the relevant command is polySoftEdge -- if you set the angle to something lower than the angle between the faces the edge will be hard; if you set it to something higher it will be soft.
