(...) You're probably right. I just remembered that the bushlocks are divided into 32 segments which is fairly colse to 48.

| | Re: high res bushlocks?

(...) I think they are fine the way they are. The basic reason is size. The bushlocks are 20 LDU in diameter. 48-segment primitives are not needed until you get to 80 LDU diameter curves. If you need to put 48-segment primitives with a bushlock, (...) (20 years ago, 5-Jun-04, to lugnet.cad.dat.parts.primitives)

I think that the bushlock primitves should be updated to align with the 48 segment primitves. What do others think? (20 years ago, 28-May-04, to lugnet.cad.dat.parts.primitives)

And 1 x 4 and 2 x 2 groups are common enough to get at least 7 lines saved. In the 700.dat you posted, just using 1 x 4 (...) (21 years ago, 18-Nov-03, to lugnet.cad.dat.parts.primitives)
