Converting large mesh file

[SGoldthwaite]

I have an STL that I'm trying to convert to a body (direct editing, not parametric).  My PC is Windows 10. I've got the new version of Fusion 360 (July 2021) that has the new and improved mesh capability.   My STL is pretty big, 1.4 million triangles.  I have had Fusion working on this of a couple of days now.  On the top of the Fusion window it says "Autodesk Fusion 360 (Not Responding)"   This happens when a program is really busy or if the program has stopped working properly.  When I look at Windows Task Manager, it shows Fusion is using about 13% of my CPU and 1000 MB of memory.   Since Fusion is using CPU and memory, I'm assuming it's still working on converting the file verses it has crashed.  Does this seem right?

I have normally found even if the Task Manager reports resources being used, unless the Memory, being used, is not steadily increasing the the application, no matter what it is, is locked up.

Can you Attach the original *.stl file here for a quality check?

I attached the STL

Sooo.....

Ignore the Makerbot label in the screenshot. It's simply the Meshmixer default.

For the other participants, this is how the mesh looks like:

Did you prepare the mesh in any way, and if so how ?

What conversion method did you choose ?

[SGoldthwaite]

I did not prepare the mesh in any way. It seems to be error-free. I used convert mesh functionality, Operation=Base Feature, Method=Prismatic

[TrippyLighting]

This is not really what I'd call a prismatic mesh. Prismatic means without arbitrarily curved surfaces (NURBS). If curved then circular fillet type surfaces.

Before even doing that, it's a good idea to create face groups. However, this is a large mesh and I did not have the patience to even wait for that, so I stopped the process.

New functionality is usually tested best with geometry that gets successively more complex.

Thanks.  I'll just leave it as a mesh..
