I actually have 2 questions. I don’t want to make a separate topic for each as they are kinda both in the same vein anyway…kinda. 1st, what does the mesh analysis do? 2nd, when you split an edge and they’re sitting on top of each other, is there a way to select the 2nd/alternate edge if you don’t want the 1st to move?

I only know the first one, mesh analysis can show you handy visual representations in edit mode for 3D printing for example, like intersecting geo or mesh thickness.

for the second one, I don’t know if there’s a better way (I’m sure there is) but when I split an edge I usually just click again, that’d select just one of them and move it.
