Need free blueprint software??

I am in process of trying to design a floor plan and was just wanting to see if there are any free floor plan design programs on the net

You can find some free cad programs out there..
They tend to have a learning curve to them though...

I tried a few then ended up buying "instant architect"...it's "okay" but doesn't have plumbing fittings for a plumbing layout.. definitely a learning curve but very useful. It has a large library but not as good as other programs I looked at. If you go for it get the Instant Architect 3-D... there are definitely better programs.
