Again, I'm not an expert on naming conventions. But it makes sense to me to name a Duplo piece after the corresponding System piece and append it with "_d". But if someone more up on this sort of thing has a better idea, by all means correct me (not (...) (24 years ago, 4-Jan-01, to lugnet.cad.dat.parts)

Whoops- I forgot to add something... this is a working copy only. It certainly needs work. Mainly, it has none of the interior ribs. I'm just posting it because I am already using it as a standin piece right now. If someone else wants to do it (...) (24 years ago, 4-Jan-01, to lugnet.cad.dat.parts)

2nd reply to my own post... After realizing that the inner bits aren't really all that hard (time-consuming, perhaps, but not too hard), I added the interior ribs and associated lines. I hadn't planned on doing this today, but it's been quiet around (...) (24 years ago, 5-Jan-01, to lugnet.cad.dat.parts)

(...) To find the correct part number, take a DUPLO 2x4 and examine the underside. There should be a 4 or 5 digit number stamped into the part, usually on the underside of the top. This is the part number. (...) standard. The next available number (...) (24 years ago, 5-Jan-01, to lugnet.cad.dat.parts)

(...) Strange. I named the Scala stud to Stud5.dat, but someone renamed it to StudSc.dat. So I thought StudDu*.dat would follow that new pattern...

(...) I too have stud5.dat as the Scala stud. As I further cleaned up the 2x2 and 2x4, something else jumped out at me that I hadn't seen before because the part was further off in other areas.
