Anybody know a layout program for drawing out floorplans On Mac/ iPhone
Like the program that drew this floorplan- http://tremmapping.pbworks.com/w/page/22453205/Understanding-Vis-and-Hint-Brushes
I'm guessing you think those pictures were made automatically somehow. I would guess they were drawn in something like gimp/photoshop.
Graph Paper and Pencil are the way to go.
AutoCAD
