Sorry to immediately post a follow-up to my own post, but I just noticed that RubberBlack is defined with the same 33,33,33 color (not surprisingly), and I feel it needs to be updated as well. --Travis Cobbs (21 years ago, 12-Jan-04, to lugnet.cad.dev)

| | Black seems wrong in ldconfig.ldr
|

The ldconfig.ldr file currently being distributed with the parts library seems to have the wrong definition for black. It uses 33,33,33 as the RGB color, when the official color chart uses 51,51,51. Two things to note. First, 33,33,33 comes out (...) (21 years ago, 12-Jan-04, to lugnet.cad.dev)

It struck me as odd that the 3673 Technic Pin (no friction) and the 4459 Technic Pin with Friction looked identical. Why are they the same? Where is that friction? I feel there should be a line of connect primitives that clearly show this friction. (...) (21 years ago, 12-Jan-04, to lugnet.cad.dev)
