Hold on, I think I managed to get it myself. I had to re-align the axis to the polyhedron THEN copy paste the shape into a fresh instance of Sketchup. A bit of a pain in the ass, but it seems to be giving me the alignment I want. This is what was happening ^ This is what I wanted ^ Note the colored edges that indicate that they are aligned with the various axis'. The first model wasn't oriented properly after an copy, move, and 180 degree rotation. Now it works perfectly since I was able to get the shape oriented. Thanks for the help, I'll post info on my model when it's done.
