Is there a need to upload unpatterned versions of parts that have appeared in patterned variants only? (For example most Bionicle dual injected parts) And if no, are such unpatterned versions allowed on the part tracker?

Is there a way to find subfiles that are used in a patterned part, but is not used in the unpatterned version of the part?
IMHO it's bad practice to derive a new subfile from an existing part and then not update the file it came from.

Hi,

I was wondering if someone could make these:

Thanks!

I feel like I'm under-using LDCad's advanced rotation capabilities. But instead of a question, I think it's easier to just give an example—and sort of a challenge. 

In the attached test file I have an oddly-shaped piece that I want to rest on the ground, here represented by a nice big tile. This part has four lower extremities, all with different y-values, and to be realistic it would need to rest against the lowest three of them. What's the best way to do this using LDCad?

Here's how I would approach it:

1. Find the lowest point and set it as the rotation center. You could use a helper part or a marker, but how do you find the point itself? Easiest way would be if you could directly select the vertex—LDCad can't do this, but LDPE can.
   
2. Find the next lowest point the same way, then using more helper parts and some trigonometry (or the handy, but unofficial, right angle calc script), rotate the part so this hits the ground.
   
3. For the final rotation, select the third low point, and rotate around a vector formed by the first two points. LDCad does allow custom vector rotation—but how do I find the vector and enter it into the rotation dialog?
   

I think part tracker would benefit from having a way to select number of changes displayed per page in Parts Tracket activity section. You can already do that by changing link, for example: 
https://www.ldraw.org/cgi-bin/tracker/ac...gi?n=0,100 gives 100 edits per page, also (and similar thing is applicable to other variants) clicking "next" does indeed offset list by 100 
https://www.ldraw.org/cgi-bin/tracker/ac...cgi?n=0,20 gives usual 20 edits per page
https://www.ldraw.org/cgi-bin/tracker/ac....cgi?n=0,1 gives 1 edit per page (why? idk, just an example)
This is already implemented in the section, so only thing it actually needs is a way to select that on page

Hey guys! I am currently trying to rebuild the LEGO racers 1 cars with their characters, but I am missing some essential items to make it work. Does anyone want to create these parts and add them to the parts tracker?

Hello,

does anyone have the old Lego Technic Interfaces (from the Dacta Series)?

Interface A for the 4.5V Era

Interface B for the 9V Era

Both are like Mindstorms but stationary and with more ports...

Hi, 

Is anyone working on the new rollercoaster parts?

I created a model in software using 1X1plate I created a model in software using 1X1plate

Is there a way or a script (preferably a script..) to quickly convert or convert to 1x2 1x3 1x4 tiles

thanks

The 2022-04 LDraw Parts Update has been released. This update adds 631 new files to the core library, including 391 new parts and 20 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 2022-04 here, and download the zip-file update or Windows install package here. Alternatively you can use the LDView menu option File | Check for Library Updates... to install the update.
