I am looking to create a very basic floor plan of our school to use as a "map" of the rooms. All I think that I need is something that will allow me to create a square, rectangle, and lines. Also an eraser and to put in text. I have tried Dia, Sketchup 8, but they are too complicated or too quirky for me,
Draft IT won't run on my W7 box. an online solution would also work. Something free would be nice.
