Hi,

For this hair https://www.bricklink.com/v2/catalog/cat...P=1987pb03 I would need Opal Trans Yellow which is not in the color list.

Kind regards,

Lisa

Hi,

The Submit button on the Parts Tracker is gone.

Kind regards,

Currently part 11459p01.dat has the handle hard coded and the plunger part as colour 16.

If its swapped the other way around the part can then be used for the 2 other versions of the part since only the handle colour changes between 11251pb01 to 11251pb03 and the plunger part is always red rubber.  Is that OK to change or do 2 other versions of the part need to be uploaded instead?

It would be more efficient to have one dat file cover all the parts IMO.

Is there any way to fix Part 14769p10.dat, as it has gaps between the edge of the top face and z-fighting.

Adding an ering to it doesn't seem to do anything. Just wondering if there is another way to do it?

It's not the only part with the issue like 14769py0.dat for example.

The 2025-12 LDraw Parts Update has been released. This update adds 42 new files to the core library, including 20 new parts.

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 2025-12 here, and download the zip-file update or Windows install package here.

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

What would be required in order to view LDraw files (or at least .dat) in-browser—for example, when they are attached to forum posts—in the same way that's already possible with tracker files?

I assume this would be browser-specific and probably depend on browser extensions. Or maybe it would be more like having a "sandbox" feature on this website, for sharing and viewing LDraw files without the need to download?

Just thinking of an extension to the idea discussed here…

…if LDraw code could indeed be mapped onto a surface the way bitmap images currently are, could you conceivably map an entire part onto a surface?

You see where I'm going with this—could a sticker part be authored only in its flat form, and then, when needed to be placed on a non-planar surface, could that flat part file be automatically transformed (along with its proper thickness) and applied as part of the rendering process?

Is such behavior even desirable? Or maybe the better question is, would the programming effort required to implement this outweigh the need to author formed versions of all non-flat stickers?

Hi Roland
It would be nice if, when adding parts to the favorites list, there was an option to add the current part with the current color.
Theoretically, this should be possible, since the part number and color are stored in partbin.fav.
Theoretically and practically, it is possible to edit partbin.fav with a text editor, but you need to know the part numbers and color codes.
This is not a big problem for someone who is deeply involved in the subject, but I think it is for most users.
I look forward to hearing from you.

Regards Johann

Hello everyone

I would like to suggest a missing hairpiece. The hairpiece in question is 'Wavy Hair with Hole in Back (85607)', used in 2009 on 'Willie Scott' from the Indiana Jones theme. It was only used in one set, 'Shanghai Chase' (7682-1). Would that be possible? Thanks in advance.

For the primitive reference page at:

I would suggest including links to the actual primitives on the tracker so people could view them in 3D.
