It's outside wall to outside wall. No need for any CAD.

Holly, the plan has a number of jogs, as well as some curved walls over two story rooms/stairs and so forth. Makes it difficult to get the actual square footage, and I'm not very good at geometry, LOL. That's why I was wondering if there's a way to open up the CAD files and if there's some automated way of generating the covered square footage based on the files????

Sq. ft. seldom require a geometric function, just being imaginative in determining the computation of an area's area.

While some municipalities consider room heights above the average height, an additional story, in the assessment of fees.

You can open CAD files with Draftsight , which is free for casual (i.e., non-professional) users. I think they used to be SolidWorks. You can open AutoCAD files with this program, and it has tools that are very similar to AutoCAD. I know that with AutoCAD you can select areas with an outline and have the area computed for you, and I imagine that Draftsight would do the same.

Are you counting the stairs?

Anyone can download AutoCAD with a 30 day free trial.

got autodesk design review free download. Exactly what I needed! :)

And was the square footage off?

Hopefully she found her solution already. Its been 6 years.
