Another quick question. My func_button seem to be blocking my way how do I make it passable?

Btw thanks for all the help on nodraw.

Use a logic_auto and parent it to something which can't move, a static func_brush or the like. It's kind of hacky, but parented objects are (almost) never solid.

Alternatively, you can emulate it with a func_door, and use the Passable spawnflag.
