Shell Issues

Hi, all! I ran into an issue that has me stumped.

Here's the part:



What I'd like to do is Shell the selected area at 1mm. At present the largest wall thickness I can get is .5mm. And that causes strange geometry around the fillets.

The model is a solid, so that's not the issue. I'm wondering if the geometry is flawed around the fillet detail. Or maybe the angles are too steep for it to make a wall of the desired thickness?

Not sure, since I'm not clear on what the command requires in order to work.

I suppose I could do this the hard way, but I'd rather understand how to better utilize the supplied tool.

.3dm file is attached for your perusal.

Thanks,
Patrick
