Extracting Model Geometry of ONE element within a wall assembly

I am attempting to take modeled wall assemblies within a project and extract the geometry of only one element within that wall assembly. The purpose of this script is to analyze thermal envelope and identify holes within the model. If this has already been discussed somewhere, please point me in the correct direction as I was unable to find this in a search.

Can you show your attempt so far?

I have not really attempted anything concrete so far. I am more looking for a starting point and/or confirmation that this is possible

It sure sounds possible.
You would just get the assembly. Get the elements/parts in that assembly. Then query the geometry.
Try searching for assembly or geometry intersect posts to find some starting points.
