(...) If possible, can you measure the distance diagonally across the minimum radius part of a cross axle? My guess is this problem has shown up because the concave curve at that point of the cross axles has not been modelled in the Ldraw (...) (20 years ago, 29-Sep-04, to lugnet.cad.dat.parts)

I personally round off the numbers to 4 decimals, but I’ve been known to do crazy stuff like modelling in 1/100 (max zoom in mlcad) and use 1-24 parts of high res primitives from time to time. But I would suggest you to round off to (at least) two (...) (20 years ago, 29-Sep-04, to lugnet.cad.dat.parts, FTX)

(...) Thanks for doing this, Niels. Is changing the diameter of these axles from 8 to 7.5 really worth it? They still won't fit in most axleholes, because LDraw's axles don't fit the actual geometry of technic axleholes. However, I am *not* (...) (20 years ago, 29-Sep-04, to lugnet.cad.dat.parts)
