LDConfig made from the one in the LDraw.org 2025-07 Parts Update.
This is a LDConfig file that includes the "Render Only" colours from Bricklink Studio.
(Without LUMINANCE values, I might change that in future updates)

To use it do the following:

1. Download it:
     LDConfig_plus_bl_studio_colours.ldr (Size: 55.49 KB / Downloads: 5)
   
2. Move it to your LDraw folder
   
3. Rename "LDConfig.ldr" to LDConfig_default.ldr(or something else)
   
4. Rename "LDConfig_plus_bl_studio_colours.ldr" to "LDConfig.ldr"
   

The 2025-07 LDraw Parts Update has been released. This update adds 448 new files to the core library, including 263 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.

You can preview the new parts in 2025-07 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.

Hi,

I am trying to create a phone app, and my goal is to show each step of my design (with LDCad) on the phone app the same way as shown in LDCad. I met a problem when implementing the behavior when a step rotating on Z.

Below is a step having no rotation:


But when I just rotate it around Z for 30 degrees, it is rendered like this:


From what I see, it is more like rotating on Y and X for some reason. But if I open the same step in LPub3D, the render is expected as below:



Could anyone help me to understand what is the logic behind this in LDCad? Or can it just be a bug?

Thanks!

The Duplo cannons are composed of multiple physical pieces screwed together. Looking specifically on the cannon with locking ring and red button 17178c01 or 94886c01.

What is the minimum that need to be modeled?

Some motors, projectile launchers, and springs have been modeled down to each screw and separable part even if that has meant the creation of (sub)parts with u numbers. Obtaining subpart numbers and internal structure requires opening the assembly, possibly destroying its play-ability in the process.

Rubber insets are sometimes modeled only by their visible parts.

Can the firing button be modeled as a red surface or does it need to be a separate subpart?

How accurately does the internal structure (metal spring and projectile guides) need to be modeled?

Do the screws need to be modeled as separate parts?

Hi,

this version gives you just a pair of small improvements.

BrickLink lists two duplo cannon balls:
54043 Duplo Cannon Ball 1/2 with Large Axle Connector
54043b Duplo Cannon Ball 1/2 with Large Axle Connector and 4 Holes in Top
These parts have visibly different geometry, the newer is more reinforced and has 4 holes.

How should they be numbered in LDraw? Keep 54043 and 54043b or go with a and b versions?

I've long struggled with parts that have two curved edges close to each other, but not having the same point of origin. The task is to fill in the area between the curves.

If the curves are far enough apart, I can use tndis and chords. However, if they are close, then I'd have to rotate chords and tndises, which isn't ideal.

Luckily, we have tang for the inside (in yellow). This eliminates the need to rotate ndises, but effectively doubles the number of points. If the inside and the outside of an area to be filled have significantly different number of points, then the result is a large amount of extremely narrow triangles, so this is to be avoided.

What if we had an inverse tang (in black) to be used for the outside? With an equal number of points, it is easy to fill the light gray area with quads.

Hi all,

I think I found some duplicate triangles and quads in some part files. Here are the ones I've managed to identify so far:

- Line 84 in 18922.dat
- Line 26 in 99781.dat
- Line 17 in 2630k02.dat

From what I can tell, removing these lines should have no effect on the geometry other than removing the duplicate faces.

I’m new to LDraw, so please let me know if I’m overlooking any conventions or reasons these might be intentional.

Thanks!
