No offense, but that reply doesn't help me at all. Did I say I wasn't looking for CAD? There are countless CAD apps out there! It's not like one can google "CAD" and download the program called "CAD" that will do exactly what I'm looking for. The apps I'd seen after a little searching weren't oriented towards *2D* design for *buildings*. There are non-free apps that are meant for home design complete with a 3D walkthrough, furniture, wall paper...but I don't need all that...and its not free.
The needs are simple, and it would be a waste of time to use something like SketchUp when all I need is a birdseye view of to-scale walls (length only) with symbols for doors and windows. Like a simplified blueprint.
It would also be a waste of time to use an application like Wildfire (not free) which is geared toward mechanical design.
We have 9 buildings with hundreds of rooms a piece. It's not a simple project and we'd like to make it as simple and efficient as possible. I was hoping someone might know of something free we could use.
