The programs I use to create Mazes.

There are five primary programs I use when designing mazes:

AutoCAD
Illustrator
SketchUp
SmartSketch
Minecraft

In addition to these five I also use a number of other programs, mostly as thinking aids. They are Notepad++, MS Paint, Excel, Calculator, and my broswer of choice, Google Chrome. Also, do not forget good old pen and paper, mostly graph paper.
