It's been a while since I've used CoDRadiant, I've been mostly using UnrealEd so I'm a bit confused on how to once again use CoDRadiant. I have everything I need in as far as models, skybox textures, etc. However, I've forgotten not only the term but also how to reshape items; like making edges on the side of a wall to make where the attic would be and what a roof would stand on. I know it's not the vortex tool, but it's similar.

Thanks for any help, I feel like such an idiot for asking such a question but figured it'd at least get answered in this forum.

do you mean such an edge=
