LDraw.org 2023-03 Parts Update Now Available

[Orion Pobursky]

The 2023-03 LDraw Parts Update has been released. This update adds 539 new files to the core library, including 429 new parts and 6 new primitives.

Thanks are due to all the part authors who created or corrected parts for this release. The small, but dedicated, band of reviewers also play an important role in keeping files moving through the Parts Tracker and deserve just as much credit. This update wouldn't have been possible without their dedication and attention to detail.

I'm going to call this the Leg Update. We fixed the Minifig Leg parts and completed a massive effort to update all official files and obsolete the old ones. We then decided to go ahead and approve every Minifig Leg part on the tracker. This update include Minifig legs of all sizes and patterns.

You can preview the new parts in 2023-02 here, and download the zip-file update or Windows install package here.

This update also includes 2276 parts that have been updated to CC BY 4.0 . These files are included with only the license line updated (as opposed to the the normal process of updating the !LDRAW_ORG line and adding a !HISTORY statement)

Thank you to all the beta testers and parts authors who continue feedback for the new PT software. This project would not was it is without your help.

Thank you for this update! I can confirm that there was a massive improvement over the last release concerning the number of parts that are now released under CC-BY-4.0. Here is the situation as it was with the 2302 release. I sorted parts by popularity according to the rebrickable database of LEGO sets.

• of the top 100 parts, 41 were not CC-BY-4.0, namely 3710, 54200, 3666, 2412b, 3623, 3622, 2420, 43093, 32062, 3437, 3460, 6636, 85984, 3713, 11477, 3034, 2357, 3700, 4519, 15068, 59900, 87580, 4162, 87087, 3008, 2877, 6091, 32054, 4477, 44728, 6536, 3705, 3749, 3011, 6541, 2540, 60897, 3832, 3037, 48336, 3701
  
• after removing all parts and primitives that were not CC-BY-4.0, out of 23955 parts, only 4402 remain (18.38%)
  
• after that removal, out of the top 100 parts, 98 were missing
  

The situation now with the 2303 release is this:

• of the top 100 parts, 7 are not CC-BY-4.0, namely 3437, 87580, 87087, 32054, 44728, 3011, 48336
  
• after removing all parts and primitives that were not CC-BY-4.0, out of 24488 parts, 9086 remain (37.10%)
  
• after that removal, out of the top 100 parts, 38 are missing, namely: 3005, 2780, 98138, 3622, 4274, 3437, 6636, 3039, 3713, 4032a, 3660, 11477, 3665, 3700, 3941, 61332, 15068, 59900, 87580, 87087, 3008, 30136, 3673, 6091, 32028, 32054, 2654, 44728, 6536, 15712, 99780, 59443, 99207, 3011, 2540, 48336, 3701, 50950
  

Here is a list of top removal reasons sorted by how many parts are directly or indirectly blocked by it:

Code:

  p/4-4cylc.dat     3275
  p/1-4chrd.dat     2830
  p/1-8chrd.dat     2234
  p/box2-7.dat      1621
  p/48/1-4edge.dat  1267
  p/48/1-4cyli.dat  1063
  p/box4-4a.dat     990
  p/2-4cylc.dat     963
  p/box3u5p.dat     703
  p/3-16ndis.dat    661
  p/7-16cyli.dat    634
  p/box5-4a.dat     594

Maybe this table can help identify which bits can be looked at next to improve the situation for the following release. Thanks!

Also during my analysis I noticed that parts/54696p02c01.dat contains a reference to the non-existing 54696p02.dat. Maybe an oversight?

This means that, despite my best efforts, there's a bug in the code to prevent this from happening.  54696p02 exists but is still unofficial.

[Nils Schmidt]

Many thanks to everyone who contributed to this release.
I have still uneasy feelings of "breaking a leg" in the past (https://library.ldraw.org/official/7097).

However, I take it with a little bit of humour. I provide the tools and meanwhile broke a leg by accident...
When I did the measurements back in 2019, I was too naive by searching for the non-existing slope.

I think we should instead remove Dual Mould. It is not used in any of the other minifig parts .

[Jaco van der Molen]

Regarding the legs:

The snap info for the new legs is missing in LDCad.
I think this could be:

Code:

0 !LDCAD SNAP_CYL [gender=F] [caps=one] [secs=R 3 8] [pos=2 0 0] [ori=0 -1 0 1 0 0 0 0 1]
0 !LDCAD SNAP_CYL [gender=F] [caps=one] [secs=S 6 5.5] [pos=10 28 -1.2]
0 !LDCAD SNAP_CYL [gender=F] [caps=one] [secs=R 6 4] [pos=10 18 8.75] [ori=1 0 0 0 0 -1 0 1 0] [grid=1 2 0 20]

(dirived from the old one and adjusted to fit the new version)

We should add that info to 3817cs02 I think?

For the dual moulds add this to the upper part 20460bs04

Code:

0 !LDCAD SNAP_CYL [gender=F] [caps=one] [secs=R 3 8] [pos=2 0 0] [ori=0 -1 0 1 0 0 0 0 1]
0 !LDCAD SNAP_CYL [gender=F] [caps=one] [secs=R 6 4] [pos=10 -2 8.75] [ori=1 0 0 0 0 -1 0 1 0]

And this to the lower part 20460bs03

Code:

0 !LDCAD SNAP_CYL [gender=F] [caps=one] [secs=S 6 5.5] [pos=10 28 -1.2]
0 !LDCAD SNAP_CYL [gender=F] [caps=one] [secs=R 6 4] [pos=10 18 8.75] [ori=1 0 0 0 0 -1 0 1 0]

I am working through the special legs.

[Willy Tschager]

Regarding the legs:

The snap info for the new legs is missing in LDCad.

No official part comes with LDCad snap info. We would have to adopt the LDcad's snap specs as we did for TEXMAP and the LSB would have to look over it before such data gets add to the library (directly into the parts or into a separate file).

Sorry, I think you misunderstood or I did not make it clear.

I meant to add the snap info to files in the LDCadShadowLibrary Roland maintains for LDCad.
For the legs means to add for those submodels.

Not really add them to them in the library ofcourse.

Roland has a GitHub repo for the shadow library. You can send a pull request for the required modifications.

[Jaco van der Molen]

Roland has a GitHub repo for the shadow library. You can send a pull request for the required modifications.

I know and I did for some parts. I had contact with Ronald too.

However, this method is not really friendly and a lot of difficult work. For me.

What I am looking for is an easy way to contribute to it.
In LDCad it is rather simple to add connectivity snap info and save this info.
I use an unpacked version of the shadow lib local.

These file do not have the correct header. It would be so much easier if LDCad wrote files with the correct header.
I then could upload dozens of snap files I made.

The ability to send automated pull request from logged in users of the PT via a web interface is possible. Implementation will have to get in line with all my other long term library projects.
