"Splitting vertices is unwelding. Combining vertices that are in the same position is welding."

Cool. I learned something today :) Thank you.

And yes, I am quite familiar with control loops, filleting and chamfering to adjust the roundness of an edge. The technique I was pointing out is how to keep the edges Sharp so Poser doesn't round them. Especially useful for the individuals still using older versions of Poser.

I must remember to remember what it was I had to remember.
