Yep it's a LiDAR based scanner, I don't rent it though my colleague owns it and I borrow it from him. I have access to the software for it, Leica's software is called cyclone, which is great, but It isn't all to mac compatible so I need to be on a computer with a license to use it. That is where sketchup comes in, I'm trying to see if I can use it effectively vs other software as it's free and works on my mac.
Seems if I decimate the point cloud to sub 10k points there are no problems, so I'm just rendering small parts at a time and them bringing the surfaces together.
