I'm training a vision model to identify LEGO bricks, and I am now exploring the use of synthetic images of bricks from all angles rendered by Blender.
Overall it seems improve the models accuracy, but recognizing the Arch 1x4 did not improve significantly with the synthetic images.
I suspect it has to do with my bricks not looking like the synthetic rendered ones from beneath.

Is this something that should be updated in the LDraw parts library?

... and does anyone have a gut feeling of how common this difference would be?


If anyone is interested. I have published my notes and code here:

Now that Minfig categories are done and implemented let's discuss Figure.

First: Do Minidolls need their own category?

Second: I think Figure should be similar to Minifig

Figure Head => Heads (of all types)
Figure Upper => Torso assemblies (of all types)
Figure Lower => Hip and leg assemblies (of all types including one piece molds like the mermaid tail)
Figure Leg => Legs (anything that connects to a hip piece)
Figure Hips => Hips (of all types, one piece molds that don't have, for example, movable legs should be in Lower)
Figure Arm => Arms (including arms with integral hands)
Figure Torso => Torsos  (of all types)
Figure Hand => Hands (of all types)
Figure Body => Figure, minus the head, that come as one complete unit
Figure Assembly => Figures that come completely assembled (including head) in the box or complete Figure shortcuts

The 2026-09 LDraw Parts Update has been released. This update adds 161 new files to the core library, including 121 new parts and 9 new primitives. As of this update, the LDraw.org Parts Library contains 17164 unique shapes or patterned 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 2026-09 here, and download the update 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.

Note: The Windows installer will be delayed. I will post an update to this thread when it is available.

modelling in ldraw has never been anything i am good at basic pieces sure but complex pieces like bionicle no thats why i have to rely on bi meshes unrelated to ldraw and for fun i modelled a character first it was a cub and i insetted the top of it and extruded the head and i put subdivision surface these are the wip pictures

the eyes were from a tutorial https://www.youtube.com/watch?v=36XDlWmJDdY
 however i didnt like how there was no red in the back so i added it myself
note blender freezed
