I've had the underside of a motorcycle scanned using a high-precision laser scanner, and have received the results as STL. The biggest file is 500Mb
due to just over 10 million facets.
I seem to be able to work with files of around 75 Mb, although TC crashes fairly frequently. But what frustrates me, is that it appears TC is making very little use of my well-spec'd PC's hardware. I'm running 2018 Pro (64-bit).
I've downloaded a trial of Rhino3D, and it works with the mesh like it's nothing. But I don't have the inclination to learn another programme. I don't understand how Rhino can make such light work in comparison, it feels like about 1% of the effort!
Any tips to make TC work better, i.e. make more use of my hardware? I'm using a i7-8700K @ 3.70 Ghz with 32 Gb RAM on Windows 10, plus a good GPU (though I doubt that's relevant).
The only option I can think of is to reduce the meshes in Rhino, which is easy, and xRef them. I would have thought the referenced files should work better if they're TCW, but I'm not sure this is the case either...
