When using Part Designer the bottom tube's walls are too thick.
If we compare with normal Lego parts the Part Designer's pieces have 1mm
thick wall (in the bottom tubes), and the Lego Parts have 0.5mm (approx.).
Can we configure that? I would like to have a wall thickness close to the Lego
pieces.
Tubes are 0.8 mm-thick, that’s 2 LDU (LDraw Unit).
They are the right size to:
1. fit a stud inside (4.8 mm diameter),
2. fit between 4 studs with a small tolerance (exact diameter would be 6.5137 mm,
it’s 6.4 mm).
In order to change it, you’ll have to change the whole LDraw library. You can
try and discuss that on the LDraw forums, https://forums.ldraw.org/ , but I don’t
think they’ll agree to it
