What is the struct that houses polygon data?

I’m looking to create a Platonic solid and I’m wondering if there is a convenient struct in UE4 that I can jump off of. This struct doesn’t need to be drawn to the screen, but I figure UE4 already has a container that I can use with pre-built in functionality. I’d imagine it would have vertex locations, edge, face, and then all the cool stuff for finding centers and edge length, and so on…

Any ideas?
