Ok, I can announce that my code actually orient ~10000 faces of 2560,
BUT 4.
In a previous version, 40 faces remain unoriented. After I checked all
distances between the ~12000 of the part, I have discovered that some
distances were very small (less than .1 ldraw units). Thus, I have added
a tolerance option that allow the user the choose the minimum distance
between points. If the distance between 2 points is less than the
tolerance, points are considered the same.
I plan to study the distance distribution in all parts to check for
rounding problems. Then I will have to check other parts. I started with
some technic bricks. 3700 and 3601 are ok, but 3703 need a tolerance of
0.01 (rounding problems again!).
I really think my code can do a pretty good job in automatically
orienting faces!
