centering rings in Rocksim

When I try to print out a centering ring using Rocksim, what I get is a solid filled black circle. Also, the mass of the centering ring changes (as one would expect) with thickness, material, and outside diameter. But changing the inside diameter does not change the part mass. And it appears that centering rings are rendered as solid in the 3D mode. So, what gives? The program seems (from what I can see) to completely disregard the inside diameter of the ring. Am I doing something wrong or missing a setting?

Nobody knows?

Post a file with the issue.

OK, I'll have to do that later. But, FWIW, the issue is present on every file I've got...

I'm sure. I'd like to look at one where the centering ring prints like a bulkhead.
