When they sold me the package they said Ai would work well, I have looked at it but can't seem to find any templates to use..
I use a CAD program that was designed to work with Ai for years- Hot Door. It is an architectural plugin (I guess you would consider it a plugin). It works great but a little pricey- well worth the price if you do this a lot. Hot Door
If you want a single purpose program, http://www.homedesignersoftware.com/ has several versions at different prices
