Just to let you know, I'm a professional draftsperson. I use AutoCAD on a daily basis, along with several other professional 3D modelling software packages.
Chief Architect's (or Better Homes and Gardens) lowest end program Home Designer Suite is super easy to learn and use. It does a great job and it's cheap. It actually designs in 3D when you're drawing in 2D.
It gives you a simple material take off, if you create your design accurately. I used it to design one of my cabins (16'x16'). I then exported the design to AutoCAD to tweak it to exactly what I needed.
Here's an example of what your 2D drawing in Home Designer Suite would look like;

And here's an example of what that 2D drawing looks like when switching to the 3D view;

Lastly, here's a simple export of the materials list to a text file;

as well as a screen shot of what the materials list looks like in the Home Designer Suite program;

Do NOT PAY Autodesk any more money for software that you own. They won't tell you this, but you can run a virtual machine with your older windows software. It doesn't allow it to connect to the internet, so there's no worry about getting a virus. If you still own your copy of the previous windows, you can get free VMWare software for personal use;
Install the VMWare.
Install the Windows operating system.
Install the CAD software.
Keep using the software that you own....
