Vertex & edge manipulation

[ether]

I read in one post that you shouldn't use Vertex level editing, but use edge manipulation instead. Any clues on how you move edges, as i've only been able to do vertecies?

As for vertex manipulation, i've had good success on moving vertecies on existing brushes, but any time i move one on a builder brush and do any CSG operation with in on the world, it creates errors (Hall of mirror effects)

That was probally me that said that. What I meant was that, just don't move 1 vertex at a time and leave it there. Move that edge instead as this will reduce any possible problems.
