Creating a shell crashes Fusion360

mwkenna — Thu, 24 Nov 2022 12:45:34 GMT

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

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.
