extrude to object causes crash

When extruding to an object fusion stops responding.  The target object is a solid created from a scanned mesh so is very complex.

Do you get an actual crash report?  Does Fusion stop running, or is it just very busy?   My guess is that the complex geometry is causing very long compute times.  This is different than a crash.  How long have you let it run?

 

If you share the design here, we can take a look at it.

On one occasion the I let it run 24 hours and it did not complete the extrude, but the MacOS did not complain about fusion not responding. On other occasions Fusion did not actually crash but the OS indicating that it was not responding for several hours.

I have found a work around where I extruded by a fixed distance past the object surface and then used the combine tool to find the intersection of the two bodies and delete the overlap. This compute completed in a few minutes, so it does not seem that the computation time of the extrude to object should have been the problem.

Here is a link to the design. https://a360.co/3J2r1P7. Body 26 was the problem.

My immediate issue is resolved, so I am happy to close the case unless you want to follow up some more.

Thanks for the model.  Yeah, that geometry in the "shell" body is pretty complex, I can see why it takes a long time.  I cannot say whether it would ever finish or not, TBH.  I'm glad that you found a method that works for your goal.  Combine and To-Object Extrude do use different methods, so it is not surprising that they take different amounts of time.  Not sure why there is SO much difference though.  If I have time, I may investigate further.
