 | | Modelling ! —Rui Manuel Silva Martins
|
| | | Has some of you may remember, I have modelled the super car (8880) wheels and tires, but when I modeled it I used Metric measurements (millimeters). I would Like to know if there is an approved standard for a convertion ratio, between millimeters (...) (24 years ago, 9-Jun-00, to lugnet.cad.dev)

| | | | (...) I believe the conversion is 0.4mm = 1 LDU. At least, that's what I always use. (...) Standards are already there. They just aren't strictly enforced. As I see it, there are two basic "orientation rules": 1. Do the same thing as other, similar (...) (24 years ago, 9-Jun-00, to lugnet.cad.dev)

| | | | | (...) Thanks ! So, 1.00 mm = 2.5 LDU (...) I call this common sence, which I think everyone should use ! (...) Are these your opinions only, or is assumed buy other people too ? I agree with most of it ! (...) Check! (...) Check! (...) Shouldn't we (...) (24 years ago, 9-Jun-00, to lugnet.cad.dev)

| | | | | | (...) Some of this has come up in various discussions. I'm not sure if all of it has or not. (...) No, centering on a stud isn't necessary. Look at 3001.dat, the 2x4 brick. It is centered on X-Z, not on a stud. The same applies for all other (...) (24 years ago, 9-Jun-00, to lugnet.cad.dev)

| | | | (...) This is only an approximation. The LEGO bricks are not metric -- The dimensions are based on inches. The width of one brick is 5/16 inch and the height (without studs) is 6/16 inch. So 0.39370mm = 1LDU is more precise. I normally try to (...) (24 years ago, 10-Jun-00, to lugnet.cad.dev)

| | | | | (...) But 0.4mm = 1 LDU (also known as 1mm = 2.5 LDU) is for us Metrics a solid enough basis to model parts with. Greetings, M. Moolhuysen (24 years ago, 10-Jun-00, to lugnet.cad.dev)

| | | | | | (...) For large LEGO elements, the difference would probably be significant, so I would suggest using 0.3937mm = 1LDU. But it's normally better to measure new elements along long LEGO beams, when applicable. Fredrik (24 years ago, 10-Jun-00, to lugnet.cad.dev)

The next thing you'll know, I'll probably be buying amplifiers which go to eleven. (FU: lugnet.off-topic.fun) (...) (24 years ago, 11-Jun-00, to lugnet.cad.dev, lugnet.off-topic.fun)

If you join two baseplates with bricks or plates on top, there will be a slight gap between the two baseplates. Now, taking those two (...) (24 years ago, 12-Jun-00, to lugnet.cad.dev)
