The current PT version is on the left, while another variant using the same number of vertices is on the right. As can be seen from this view, the size of the plus shape is bigger (it extends a little further away from the centre) on the right (salmon colored).

The length of the orange bar (below) is closer to the shape on the right (above) than the shape on the left (above).

The black dots in the picture above form an almost perfect quarter circle.
The red dots above show the tapering - the narrowing of the axle main fins.

In this view (below), aided by the magenta plane slicing thru the middle, we see that the curvature at the plane is more round on the right than on the left.

Finally, the tapering is visible on the left (green vertexes), while absent on the right (yellow vertexes has no tapering).

I claim that without adding more vertexes, one cannot satisfy both a) and b) where a) is the tapering, and b) is the roundedness along the magenta plane combined with a larger plus shape.

How come the transparent colours aren't visible from the backside?

I'm reworking this sticker. It should have a transparent multi coloured print.

   

But, no matter how I try, using BFC Noclip, the colours are lost when I flip it over and look at it from the reverse side.

I just want to start by thanking the community for making tremendous progress adding many of the Most Common LEGO Parts to the LDraw database.  In talking with Orion at BrickCon last weekend, it became clear that the group has made great strides to increase efficiency in many ways, including clearing out the backlog of unofficial parts, as well as extracting new part shapes from both Unity, the Builder App, and other Unity-Based app sources.  This is awesome work!

For example, tons of the parts highlighted in this earlier thread are now in LDraw.  (Most notably, the last part in the top 1000 which was missing was DUPLO 3×3 Flower (Part 84195) - It was added in the past month and is now in my parts guide with a nice image!)

Missing parts from Top 2000 (In Progress or In Unity/LEGO Instructions App):

Hi, 

there is a new part coming out soon apparently, so I decided to make it in LDRAW for LDCAD as well as LegoScript,
I found out about it here (as well as some other new parts): https://old.reddit.com/r/Legoleak/comments/1n647vv/parts_some_upcoming_new_pieces_for_2025_via_brick/

Here is the zipped ldraw file and shadow dat file:

  1x1x2brickwith2studson3sides.zip (Size: 519 bytes / Downloads: 3)

  1x1x2brickwith2studson3sides.dat (Size: 438 bytes / Downloads: 3)

I made a simple library, the lets you use LDraw colours in OpenScad. Today I updated it to the LDraw part update 2025-08.
It is Available on GitHub and through the openscad-library-manager(still in development).
This is how the colours look like in OpenScad(I use a development snapshot):
   
Currently this can only be used to show models in LDraw colours. In the development snapshots you can export coloured models to 3mf files.
This will become a lot more useful once I get to implementing 3mf colour support in Convert To LDraw.

I recently noticed a very subtle issue with the geometry of 30022.
The parts file currently uses the same basic geometry for the top as the much older 3145: a flat top with a total height of 40 * sqrt(3) = 69.282... LDU, forming part of a perfect regular triangle with side lengths of 120 LDU.

• However, 30022 is actually slightly taller at ~72 LDU (and has been since its inception in 1996). The difference in height also affects the four studs on the front which seem to be "in system" with the bottom for 30022, which is not true for 3145.
  
• The top left and right corner are also chamfered with a 90 degree angle w.r.t. the inclided sides, instead of having sharp corners, as a transition to the slightly higher top.
  

Hi everyone,
Hi Nils,

To accelerate the sticker and pattern generation process, I’ve got another exciting news for you!

I’m partly referring to this thread: https://forums.ldraw.org/thread-23242.html on the LDraw forum. Mainly regarding the integration of Img4Dat in LDPC. 

I have no idea how many of you are still actively using the tool 'Img4Dat', or whether you're simply working with LDPC/LDPE from scratch for sticker and pattern generation.

However, I use Img4dat a lot and really enjoy it, even though it's still somewhat in a beta state. The source code and executable aren't publicly available, and the program is no longer actively maintained.

I’ve tried contacting Rolf Osterthun, the author of the program, via the LDraw forum and his webpage, but I haven’t received any reply so far. Therefore, I’ve decided to decompile Img4Dat in order to access the source code, open it up for future development, and integrate it into LDPC (see *note below).

Image 1.1 shows the decompiled Img4Dat program, including the source code opened in Visual Studio. Image 1.2 displays the re-compiled software running with a test image after path analysis. Although debugging is still in progress, the program is relatively stable and (almost) all features are functioning as intended.

   

Image 1.1: Decompiled source code from Img4Dat in Visual Studio

   

Image 1.2: Compiled program Img4Dat with test image after path analysis

Unfortunately Img4Dat was originally written in C#, whereas LDPC is written in VB. However, it's possible to combine C# and VB within the same Visual Studio solution (see Image 1.3). Mixing VB and C# isn’t the most elegant solution, but I suggest proceeding this way for now (see **note below).

   

Image 1.3: Img4Dat and LDPC 1.7.7 in one Visual Studio solution

Image 1.4 shows the compiled program running with the same test image as above, and the resulting pattern successfully imported into LDPC.

   

Image 1.4: Img4Dat integrated into LDPC.

At the moment, the program simply generates a *.DAT file, which is then loaded into LDPC. Again, this isn’t the cleanest workflow, but it’s functional for now and my current understanding of the structure of LDPC is simply not good enough to optimize it. I believe Niels could easily improve this process.

I’ve already (started) implementing several modifications on Img4Dat. The generated pattern will be projected onto the X/Y plane instead of the X/Z plane. Scaling will be based on LDU units rather than pixels, and all common image formats (.PNG, .JPEG, and .BMP) are supported for import. I’ve also updated the header file (replacing the reference to CCAL 2.0 by CCAL 4.0).

Currently, the pop-up dialog box is an exact copy of the original program, including the menu bar. However, all of this can be easily adapted now.

In case Niels is not willing to integrate the decompiled Img4Dat project into LDPC in a future release, we at least have an updated standalone version of Img4Dat, which can be further improved over time. Since it already runs independently, no additional work is required at this point.

What’s your take on this? Are you still actively using Img4Dat? Would you be interested in seeing it integrated with LDPC? Do you think I should move forward with the project? If there’s anything you’re missing or any feature you’d like to see added, feel free to let me know. I’d really appreciate your feedback!

@Nils: I could totally understand if you don't want to include the decompiled code, but I'm happy to help where I can if you do.

Thanks
Gabe

*I will not under any circumstances upload any code without permission form Rolf! If you are in contact with Rolf, please let me know or ask him for me instead. I will give him credit of course. 

**In the end, we would need conversion from C# to VB. It is possible but it will take a while, even with the help of KI. If we accept a combined VB/C# project we can already use it.
