[Question] CAD Program for Level / Dungeon Design

So I am thinking about getting a (different) CAD program to create both dungeon / level layouts as well as use that to create a 2D map / minimap with the design (rather than an overhead camera feed). Any recommendations? I originally thought AutoCAD, however, that is way over the top for what I’m using it for.

Thanks!

edit:

Most of the programs that I’ve tried, DraftSight, AutoCAD, etc… are basically vector based drawing tools. I have Illustrator for that O.o; Basically, I’m looking for something that will allow me to draw a wall X wide, Y length. steps, corners, doors, etc… I guess instead of a “drawing” based CAD program, more of a “shape” based CAD program.
