and the beautiful work you have produced here. Let's clean up
the issues reported here and bring this baby to blossom!
My greatest compliments!
some stud logos appear mirrored?
WARNING "2861.dat" Line 1179: Identical to line 1176: 2 24 431 0 40 431 0 43
correcting myself: studs are not mirrored.
but they are not all rotated correctly, i.e.,
many two neighboring studs have different orientation.
this looks very strange when displaying this part with logos.
Holding because of missing referenced parts.
train points. after initiating it some years ago, the discussion
slept in and did not consolidate the existing parts on the PT.
We last week took up the discussion again and solved it.
The result was that the origin for train track parts should be
at the center of the straight section. When updating this part,
this part should as well get that origin.

, color 383 should be replaced by 494 IMHO
because this file will become the point in "straight" position.
There will in future be a ...c00 which will be it in "branching" position.
See 73696.dat and 73696c00.dat for the analogy.
IMHO, c01 then should become 2861.dat plus the yellow point handle
http://www.peeron.com/inv/parts/2866
, and c02 should become 2861c00 plus the yellow point handle
Existing certification-votes were deleted.
I have constructed several test track layouts in real world that could not be replicated in LDraw without overlap or misalignment.
This part are sitting here with no progress for almost 8 years.
If some minor details are wrong, that's fine, but it needs to be ensured that people using this part
for constructing train track layouts e.g. with BlueBrick software get correct results.
If that's ensured, I'm happy to get this out.
We need to remember that details always can be added/corrected with future PT iterations of this file.
It does not have to 100% perfect at the first shot, especially because it is so hugely complicated.
As said, main connector geometry counts for me.
