Creating a shell crashes Fusion360

[mwkenna]

I am trying to shell the bottom of this part. It's crashing Fusion every time I do so. Not sure what I am doing wrong, can anyone suggest how I might turn this into a hollow part without crashing Fusion? Thanks

Apologies - looks like it didn't upload. This should be good now

Thanks for the model.  Fusion does not precisely crash, but the shell is definitely taking a long time, and may be in an infinite loop.  I let it run for 45 mins, and it did not finish.  I will let you know if I learn more.  It might have something to do with the geometry here:

That area actually is not the problem.

One method I use is to split of the part that might be the problem and then see if I can shell the other part.

The reason is likely the surface with the small radius ending in a singularity (point).

I trimmed off the curved part and then it shells just fine:

@TrippyLighting is correct - that is the problem area of the model.  Our kernel team is looking into why this process seems to take so long, rather than just error out as it should.

Thank you - this is very helpful!
