There's a bit of a debate about U-Joint shortcuts going on on the PT.
Here's my take:
There are 2 ends and a center for each U-joint.
The ends are 3712 - https://www.ldraw.org/parts/official-par...artid=3712![[Image: 3712.png]](https://www.ldraw.org/library/official/images/parts/3712.png)
These parts have only ever come in color 7 or 71
The center has 2 types:
3326a - https://www.ldraw.org/parts/official-par...rtid=3326a![[Image: 3326a.png]](https://www.ldraw.org/library/official/images/parts/3326a.png)
This came in color 7, 71, and 79
3326b - https://www.ldraw.org/parts/official-par...rtid=3326b![[Image: 3326b.png]](https://www.ldraw.org/library/official/images/parts/3326b.png)
This came in color 7, 71
The current shortcut, 3712c01.dat, uses 3326a and is color 16 for all 3 parts
There are updated shortcuts on the PT that hard code the center color. There is some debate about these here:
