(Resolved) Error Importing a STL as a mesh into Fusion 360

When I import this into Fusion 360, the curved area gets some odd cubes forming.  I tried again.  Interestingly, the same exact distortion happens in Tinkercad, which I also tried.

The Mesh looks like a combination of 2 meshes with some internal faces left behind.

You can use Mesh -> Prepare -> Repair (Wrap) and remove the internal faces/mesh.

But the design is a bit strange with missing fillets etc, and will not easily be converted into a solid body.

What is the end goal? I'd only use the mesh for reference and remodel the part in Fusion

I was just hoping to do a quick job of cutting off those bottom "sockets" for the Gridfinity.xyz standard to replace them with corrected ones, for 3D printing.  I didn't realize the whole model was messed up, because the "3D viewer" in Windows seemed to open it normally.  

Interestingly, I just reopened Fusion360 and reopened the mesh and this time it looks correct!  So I wonder if it just has to do with load order of vertices or something.  I think I had several other resource hog apps running before, too. 

Seems like this is super minor and intermittent, so I'll close the report.  Thank you.
