Middle lindef/texture section..

[MancubusBruiser1988]

What is a quick and easy way to make any section of a wall be dragged out in a particular section without having the entire wall affected. Example.. There is a wall and I want to make the middle stick out in a square form. Similar thing goes for also a different texture in the middle of a wall. I remember it was easy to do on the old DB.

Add a couple of vertices and drag it out? Add a new sector in the shape you want, connected to the wall, then delete it to create a null space?
