The common practice for solving this problem is normally subfiling,
which I would recommend here, too:
the whole part without studs gets put into a subfile,
and then the left and right variants use that subfile
and add the studs.
For example, you can see this principle with most "Wing..."
parts. I like that approach very much (because I *am* using
such studs) and would like to have this part organized this way, too.
Can easily be done.

(I see broken dependencies above)
For comparision, see the RC point mock-up done by Thomas Burger (GrapeApe) - http://www.brickshelf.com/gallery/whoward69/LDraw/9vPoints/switchgoodgeometry.png (original B/Shelf folder - http://www.brickshelf.com/cgi-bin/gallery.cgi?f=203196, original Lugnet post - http://news.lugnet.com/cad/?n=14079)
correcting myself: all studs are mirrored.
this is probably the result of how this part had been created, i.e.,
by mirroring its Left counterpart.
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
each with their own separate partnumber.
Many of the files still use 383, (crome plated plastic) on the metal parts.
All of the studs are still mirrored.

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 2859.dat plus the yellow point handle
http://www.peeron.com/inv/parts/2866
, and c02 should become 2859c00 plus the yellow point handle

but the last versions of this file, and 2861, is a step backwards.
This part is now corrupt. Please restore Steffens version.
I had done yesterday, I think you just have worked locally
on an outdated version. I'm restoring my version right now.
Especially, I had factored-out the main point part into the s00
subpart, so this file will properly be a shortcut.
Regarding the origin, I think this train point should have
the origin exactly there where all other currently official
train points have it, that is at the center of the straight track.
we should be very careful here with the c00, c01, c02, ...
numbering to keep the best possible analogy with
the already official 4.5V and 12V train points
its current c00, c01, c02, ... assemblies,
as they are already analogous to the official other points 4.5V and 12V.
the only flaw here is that number 2859 is wrong, so u....dat is the way to go IMHO
unmirrored that.
