The 2024-02 LDraw Parts Update has been released. This update adds 326 new files to the core library, including 49 new parts and 243 new primitives.

The primitive number above is a bit deceptive. In this update we transitioned all the ring primitives from the old DOS 8.3 filename to (e.g. 4-4rin10.dat) to fully correct filenames (e.g. 4-4ring10.dat). All the newly renamed rings are considered "new" by the parts tracker software.

Special shout out to Willy Tschager who rewrote all of the CC_BY_2 primitives. They didn't all make it into this update but we'll try to have them ready for 2024-03.

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.

You can preview the new parts in 2024-02 here, and download the zip-file update or Windows install package here.

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

Hello,
i dont find in the instruction app theres another way to find this piece?
is the new elf hair for the rivendell set.

https://img.bricklink.com/ItemImage/PN/1...53pb01.png

thanks as usual

Starting tonight (3/23, my time, PDT) and continuing into tomorrow, there will be some intermittent extended downtime  while I perform sone backend upgrades to our entire web ecosystem. This is to prep for an OS upgrade that will happen in April. Once this is done parts the update will go out.

I've been encoding my own modified version of this official, new set, and I created a couple of mock-ups for two of the new patterned pieces from this set. I thought others might want to use these two patterned parts, until such time as better versions become available. 

Hope this helps. 
Franklin

Hello,

I really need help from the Jedi of this forum. I recently bought a new computer with windows 11 so I downloaded the package with all the files and install them with no problem... BUT.. even if MLCad works fine the LSynth commands are gray and the parts are missing from the library?!

Of course I changed the path to Lsynth in MLCad.ini, scan the library many times, try to install the program again, de-activated the antivirus but nothing worked.
Does it happened to anybody else, do you gents have any idea what the problem is or coming from?

Thanks for your help.

While I am still trying to prepare an automated mechanism to help identify top missing parts based on my Most Common LEGO Parts analysis, here's an old-fashioned list of the top parts from 2023 or 2024 which aren't in LDraw yet...

Rankings are based on those sets released so far in 2023/2024 - if you bought one of every set and sorted by part and color.  (It is a weighted scoring that factors # parts, # sets, and # colors.)

RANK - Part Number & Name
3293 - LEGO PART 3277 Hair Mid Length, Parted
3448 - LEGO PART 35494 Hair Mid-Length Wavy with Center Part
3563 - LEGO PART 2149 Wave / Lightning with Axle Hole
4127 - LEGO PART 4986 Large Figure Cover 4 x 5 x 2 with Bar, 4 Studs, Ridged
4243 - LEGO PART 5065 Panel 6 x 5 x 3 1/3 Curved Top
4320 - LEGO PART 98876 Cockpit 4 x 2 x 3 with Pin Hole, and 2 Clips
4460 - LEGO PART 3486 Wheel Hard Plastic Large, D.36, with 4 Studs
4461 - LEGO PART 2144 Large Figure Weapon Sword with Axle Connector

I know they aren't wildly popular parts, but they are potential up-and-coming parts and I thought it might be a useful list for folks looking for interesting parts to add to the collection.

Sincerely,
---Tom Alphin

From discussions in the parts tracker, I learned that there are different streams of how people like parts to be authored. The streams I identified so far are:
1. Use as many primitives as possible.
2. Make sure there are no manifold issues like t-junk.
3. Accept manifold issues if this leads to fewer faces.

Those streams often contradict each other because for instance using primitives often leads to manifold issues because even the most standard primitives like the studs bring them along. Placing a stud that is open on top of a box (as done for the most standard LDraw parts like 3001.dat) produces vertexes for the stud that are not connected to any vertexes of the box at all.

As such I was wondering whether it would make sense to be able to automatically generate parts from CAD files, such that I can use the full power of the CAD system, which could make sure to produce a manifold structure. This structure can then automatically be converted and we would receive a part that has a perfect manifold structure and as such should not cause any rendering issues.

The downside of this approach is that those automatically generated parts would not use any primitives at all.

If you are interested in the approach, feel free to have a look at https://github.com/schiele/stl2ldraw, which currently is an early working prototype.

This includes an example of part 3001 in https://github.com/schiele/stl2ldraw/blo.../test.scad, which gets translated into an STL file by OpenSCAD. In the next step, the tool translates this into an LDraw dat file.

The tool currently has the following features:
- Reads binary and ascii STL files.
- Merges very close vertexes that would not produce visual differences but might cause non-manifold structures.
- Warns about incorrect normal vectors in the STL files and corrects them.
- Warns about detected non-manifold structures but does not correct them:
  - degenerated faces (faces spanning no area, meaning all points on one line)
  - open edges
  - ambiguous edges
- Merges adjacent triangles on the same plane to convex quadrilaterals.
- Generates lines for sharp edges (more than 25 degrees angle) and open edges.
- Generates optional lines for soft convex edges (less than 25 degrees angle). For concave edges, they are not generated since they would never be visible by their concave nature anyway.

I do welcome your feedback and suggestions.

Hello,
while making the stickers of the 75887 set I ran into this problem: applying a sticker to a flexible part.

I thought I'd do it like in the attached files, but I can't load part 62698k03dy0.

Is my idea wrong?
Do I call the sticker from within files 62698-f1dy0 and 62698-f2dY0 without applying it to the flexible part?

Massimo

I'm shooting to get 2024-02 out next weekend (3/24-3/24). Get your reviews in. 

I'd really like to get all the primitive updates out with this update but, failing that, at least the rings.

If this body wear part could be modeled, I would be so grateful!
