Uh, you mean *ring* primitive, right? The lines you quoted are all
*flat*.
I would not use 48 segment primitives on this part - it would be
overkill.
There do seem to be some incorrect vertices on those polygons. You
could replace the polygons with the following:
1 16 0 0 0 2 0 0 0 1 0 0 0 2 1-4ring3.dat
1 16 0 0 0 2 0 0 0 1 0 0 0 2 1-4ring4.dat
(except with the correct positioning and orientation).

| Hi. I'm trying again to BFC CERTIFY some of the parts, and I've noticed some interesting things when working on 3823.dat line by line. When I got down to these lines: 4 16 -36 48 -20 -35.54 48 -22.30 -39.24 48 -23.83 -40 48 -20 4 16 -35.54 48 -22.30 (...) (22 years ago, 30-Sep-02, to lugnet.cad)
