as a former engineer i know how to use autoCAD, powerCAD [the apple version], and microstation [the cheapo student version]. since i am... not an engineer currently i don't have access to any of these programs and am not paying for a license. i know i can use a free version of autoCAD, but mnehh. i didn't really like it when i had to use it.
being highly adaptive.. ..i googled "free cad programs" and happened upon this mini review of the top 5 free CAD packages on the interwebs. being a sucker for pretty much anything google and free, i downloaded google sketchup and proceeded to watch the intro tutorials. hours and hours later on a saturday night i drew up a preliminary 3d sketch of my bathroom remodel. unfortunately in 3D it turns out ... thaaaats a shitton of furniture [?] in a very small room.
my bathroom is 6'x6' and i am not willing to expand into my already very small bedroom or very small kitchen. so tonight after work instead cooking, i modified some stuff and added a smaller counter and above-the-door storage. and voila!
