Hi all: Suppose there were a part such as a 3x9 brick with "Dave is Supercool" printed on the side, and let's call it part 65432. If that part did not exist in non-printed form, how would this be entered into the LDraw inventory? That is, would the (...) (19 years ago, 28-Apr-05, to lugnet.cad.dev)
