Best way to extract specific faces from complex mesh?

Hey everyone, I am currently looking for the best/fastest way to extract just the bottom mesh faces in this X so that I can make it its own combined surface. I could use extractmeshfaces but that would require me clicking on every single face and there are more parts to do then just this one X.

Any ideas?

Thanks.

Did this start as a SubD?

No it was a downloaded STL

Try the _SelMeshPart command
