@hpks77, you did not mark your link as "allow item to be downloaded", so we can't get the model. But, I can tell just by looking at the A360 view of it that this is not going to shell. All the small features, some of which are pointed out in the image below, will most definitely block the shell. Small fillets are a problem, as are the small holes in your model. Knowing where to put the shell in your feature history is a bit of an art form. You want it before you start adding lots of small details, but late enough so that the main shape is there.
Thanks for the tip! I'll give it a try. If that doesn't work then, I can try to shell it in Inventor.
you are certainly welcome to try to shell it in Inventor, but since Inventor and Fusion share a modeling kernel, I'd be surprised if you get different results there. If you do, then it is definitely a bug in Fusion, so let us know.
Thanks!
Jeff
