I find Fusion is much more crash prone than 123D was. Sometimes I revert back to 123D to do operations Fusion deems impossible.
Here is a screen cap of the model I'm trying to shell. The highlighted blue faces are what Im trying to shell from. It crashes everytime I try. My computer is by no means weak.
From a glance without actually having the file i'd say yeah i'd expect some issues depending on the thickness. This area most concerns me:
So I separated that top arch portion as its own object and got it to shell to 1mm in thickness but anything else throws this error at me. I'm shooting for 3mm since this is a pretty big part.
"Error: The body could not be repaired after deleting faces.
Try changing the selection, or use the Delete tool in the Patch workspace to delete geometry without repairing the gap."
The frustrating part is things keep crashing if I ask it to do more than it can handle.
Alright figured it out. I had some tiny surfaces that stuck out on the face of the bigger screen part that I isolated when I was applying a fillet to it.
The problem area on the top part was a couple of those bigger interior radii oddly enough. I deleted them then was able to apply the shell and add them back in after. Could have been because they are fairly complex the way they follow the inner face.
The last image is what came before these cad files. I originally designed and built this just off of some scale line drawings I made in Adobe Illustrator since I hadnt taught myself CAD yet. That was built out of mdf, wood and various other materials I bought at my local big box stores. I'm trying to take it all a step further and get my design molded out of plastic. Sadly much to big for 3D printing.
Thanks for your help.
That would do it. Most of the problems we see with shell are when its computing rather complex geometry and there are 'pinch' points where the compute can't solve - like a conflict or an area were the shell would touch. Simplifying the amount shelled with a split body is a good approach. But the best approach is to shell prior to do doing big fillets and chamfers.
