Getting volume of building materials

[sirduncan02]

I've read through the AC Calculation Guide, read many blog posts and several tutorials and can not figure this out.

I'm working on the database and properties and linking and I can get the volume of a wall.

But how to I get the volume of just a skin in a composite wall? I have an 8" Concrete wall (with a 'Structural Concrete' Building Material), as well as an air gap skin, a framing skin and a Gyp board skin.

I currently need just the volume of the concrete in this composite.
And while I'm at it - I'll need a total volume of concrete so I also want the schedule to read from a simple 8" concrete wall.

I just can't seem to figure it out. Can anyone direct me better than the semi-blinded bumbling I've been doing for the past couple of days?

Basics first: you did create a Component Schedule (rather than an Element schedule)?
