Ldraw Unit (LDU)

SLIDE 9
Bricks are 8mm wide by 9.6mm high How do you make widths and heights match?
SLIDE 10
LDU makes the math easy.... How many plates = how many studs?
2 studs = 2x20 = 40 LDU 5 plates = 5x8 = 40 LDU
2 studs = 2x20 = 40 LDU 5 plates = 5x8 = 40 LDU
SLIDE 11
How many bricks = how many studs? 6 studs = 6x20 = 120 LDU 5 bricks = 5x24 = 120 LDU
SLIDE 12
6 studs = 5 bricks = 120 LDU (or 15 plates) 4 studs = 3 1/3 bricks = 80 LDU (or 10 plates) 2 studs = 1 2/3 bricks = 40 LDU (or 5 plates)
SLIDE 13
Since 1 stud = 2 ½ plates, no combination of plates adds up to exactly one stud
SLIDE 14
One answer: brackets. The thin vertical plate is ½ the thickness of a normal plate, or 4 LDU
SLIDE 15
Bracket vertical part is ½ plate thick ½ plate from bracket + 1 plate + 1 tile = 2 ½ plates, same as 1 stud
SLIDE 16
Exception
SLIDE 17
Technic pin hole placement is just a little higher (about 0.2mm) than stud-on-side placement. Some models may have alignment problems due to this. Reason: early Technic brick molds needed thicker plastic between pinhole and bottom of brick.
SLIDE 18
Use bricks with studs on sides to attach assemblies at 90 degrees. To mount them flush, remember that 5 plates = 2 studs = 40 LDU.
SLIDE 19
Use half-plate offsets to add texture to an otherwise flat wall

SLIDE 22
How do you make a gentle slope? What if these are too steep?
SLIDE 23
For a more gradual slope, we'd like to mount every other one ½ plate higher But, we have a half-plate hole to fill! How to attach these?
SLIDE 24
Alternate rotations for headlight bricks to take advantage of ½ plate offset in “foot”
SLIDE 25
The 1x1 “cheese slope” is a very useful part but doesn't combine well with others of its kind to make a smooth slope. This notch is needed for it to fit a stud inside, but is ugly.
SLIDE 26
Turns out that “notch” is ½ plate thick. 2 plates (height of cheese slope) + ½ plate = 1 stud
SLIDE 27
Mount the center slope ½ plate lower for a smooth surface!
