Cool project, but just how many polygons are you talking about? Also, my guess is you did meshes, instead of breps- they are far more efficient in my experience. The largest mesh I worked with in Fusion 360 is a digital elevation map of California, it has 2.8M vertices and 5.6M faces and it's still possible to get things done (like making a CAM to carve a 2 foot x 2 foot map with reasonable details).
