I am trying to upload a .stl file. The file its self is a x-ray tomography scan (basically a 3D image created by x-raying a real life object) of some glass beads surrounded by resin. However when I upload it I get the bellow error message. I’m not familiar with autocad (or similar software) so I am not sure how to fix my model. Could you tell me if its an easy fix and point me towards a tutorial that could show me how? I have access to most of the autodesk softwares. Its a fairly complex shape made up of lots of triangles (sorry if thats that wrong term!)
