Any Train fans that could make instuctions for me? |

I'm a huge train fan and wanted to make instuctions of my designs to share with my LUG. I've only recently learned of ldraw and it seems a bit out of my leauge. I have about 10 right now that I would want done. Would anyone want to make them for me? I'd be willing to let you pic one for free if you were willing to make say, 5 of them? I just don't have the time to learn another program, let alone sit down and actually make the instuctions.
If you're interested just reply and we can chat.
Thanks!

some thoughts about train track part origin choices |

At part
http://www.ldraw.org/cgi-bin/ptdetail.cg.../85977.dat
some questions arose about where to put the origin of train track parts.
The X and Z choice usually is not a problem, both for curved or straight parts:
we there can simply follow the principles of our usual practice, i.e. "part center".
This is also what existing parts do, e.g. 3229a.dat, 3229ac01.dat, 3229ac04.dat.
Regarding the Y origin, there is the question
"Should the origin be (A) at the top of the studded sleepers or (B) at the top of the rails?"
The current status in the library needs to be explained historically:
The rail parts e.g. 3229a.dat existed in the library long time already.
As usual for parts, they had their origin at the top.
This origin was kept when 3229ac01.dat was created, an assembly of two curved rails.
This origin was kept when 3228ac02.dat was created, an assembly of two straight rails.
This origin was kept when 3228bc02.dat was created, an assembly of two straight rails plus sleeper.
This origin was kept when 948ac02.dat was created, a point.
This is the 4.5V blue and grey rails story.
The same origin was applied to the analogous 12V blue and grey rails, e.g. 73696c04.dat.
So to make a long story short: carrying over the origin choice of the single rail part to the rails assemblies
led to the effect that the vertical origin of all 4.5V and 12V train track parts and assemblies is at the top of the rails.
The origin question now again arises for the 9V train track.
http://www.ldraw.org/cgi-bin/ptreviewsum...aintrack9v
(with or without metal top), and for other train tracks where the rails are firmly attached to the sleepers.
There the question is if the vertical origin should be
(A) at the top of the sleepers or
(B) at the top of the rails.
Both solutions have advantages and disadvantages:
Solution (A) would make the new train track parts better match plates.
Solution (A) would be the intuitive one if one did not know about existing train track parts.
Solution (B) would make the new train track parts better match existing train track parts.
Both solutions are no problem for train track layout software like BlueBrick.
So what to do now? Current situation:
- Official train track parts out in the wild have "origin at rail top".
- *SOME* of newer train track parts with "origin at sleeper top" already "sneaked" out, e.g. 32087.dat
- all newer train track parts currently on the PT like 74746.dat or 53401.dat or 85976.dat follow the "origin at sleeper top" strategy
I have no real strong opinion here. We could opt for one of these solutions:
(i) make all train track parts have origin at rail top
(ii) make all train track parts have origin at sleeper top
(iii) let some have it this way, others the other way
Solution (i) would require to re-position official file 32087.dat.
Solution (ii) would require to re-position many official 4.5V and 12V files
Solution (iii) would create inconsistency but would minimize current trouble
After having written this, I slightly tend to solution (iii)...

Numbering error : Minifig Ski Pole |
Posted by: Christoph Mierowski - 2013-11-30, 18:27 - Forum: Parts Authoring

Right now the Minifig Ski Pole is found as 90514.dat. But at Bricklink and in LDD it has the number 90540.
I assume that LDD and Bricklink can not be both wrong- sometimes Bricklink has wrong numbers - But Bricklink and LDD at the same time with the same number - I doubt it. So this official part needs renumbering.
