The PT currently uses the forums to authenticate users. While this currently works well enough, but with the next gen PT in development, we have an opportunity to discuss what we would like to do going forward.

I see 2 viable options:

- Keep the current system with the forums being the controlling account
Pros: Familiarity. Easier to PM authors with questions.
Cons: At the mercy of the developers of the forums to not break things. Rewrites needed if we decide to change software.

- The PT and the forum accounts separate
Pros: Thing only break if we break them. Having an API to tie into is easier.
Cons: More things to sign into. More difficult to tie stuff back to the forums (like the Parts Author badges)

Now that I've pondered and written the above, I think I'm in favor of keeping the forums and PT tied together.

I've needed this part for a very long time now but still cant figure it out. I've created a file in PS and even got it over into meca bricks but I still don't know how to get it over to Stud.io. I'm hoping someone here might be able to help finish it up? Let me know what I can send you to help! Appreciate the help!

I have a PNG of the file of the decal I created in PS available. 
The photoshop file available of course too. (I used the mecabricks template) The part looks pretty good in Mecabricks
An exported version as a 3D object from mecabricks.

Heres the BL link to the part... https://www.bricklink.com/v2/catalog/cat...6#T=C&C=86

I hope thats helpful.

Hello! :-)

There is two tiger mask this and that:

And I think this is the basic mask:

Can you put together these two mask?

Thank you very much! :-)

The topic that is bugging me a bit lately, is what should be really put in priority - precise geometry, or cutting down on that a bit, to have model be shaded way more nicely? Example of that would be the cut cylinder on the 50921. It features cylinder cut by the other one. In the current version, it looks like this:
   
The thin triangles lead to a pretty unpleasant shading, which essentially keeps edges very clear
   

It can be fixed by merging some of the vertices, but that results in cylinder not being really circular anymore:
       

I am not sure which approach is favorable. First result has pretty precise shaping, but loses in appearance. Second one is more fine in how it looks, and precision loss, while present, is not that dramatic

Is it possible to get a rotation matrix for a circular primitive, given a simple (I guess quadratic) Bézier curve?

All of our curved prims are circles or conical, and I’ve read that any affine transformation of a conic section will result in another conic section. If the simple Bézier curves are likewise conic (which may be a wrong assumption), then theoretically they can all be represented by a 2D shear matrix, right?

I found a bug in the release script of the PT. If the first lines after the header are TEXMAP lines, the !HISTORY line for the release after those TEXMAP metas. I've currently found 6 affected parts in the Official Library:

parts/36069ap01.dat
parts/36069bp01.dat
parts/98088p01.dat
parts/98088p02.dat
parts/98088p03.dat
parts/98088p04.dat


If you find any more, let me know.

Note: This does not affect any visible aspects of the part. The only problem is that the header is out of compliance with the Header Spec.

I'll track the down the source of the bug and recycle the affected parts for the 2022-06 release.

Hi, I'm using this part in a MOC that I want to digitize in LDraw format...
https://rebrickable.com/parts/3660pr0005...lot-print/
BrickLink 3660pb003 • BrickOwl 259299 • LDraw 3660pr0005 • LEGO 3660pr0005

Does anyone feel like tackling this? I don't know the procedure for getting printed parts added. It has an LDraw number, but nothing in the official or unofficial parts library that I can find.

Thanks
Bill

Good morning everyone!  I have one question and I haven't been able to find it in the forums.  What are the recommended settings for my Creality Ender 3 Pro?  I've seen settings on websites that recommend a 1.2mm wall thickness with 4 layers iirc but those bricks don't fit well together without sanding.  Any advice would be greatly appreciated on this.  Also, thank you to all for having such a fantastic community!

This is the thread for City sets released in 2007 (Fire, Traffic and more)

I've found the descriptions of these two parts 45677 and 52031 are inconsistent, while creating sticker shortcuts.
45677 Wedge  4 x  4 x  0.667 Curved
https://www.ldraw.org/parts/official-par...rtid=45677
52031 Slope Brick 45  4 x  6 x  0.667 Double Curved
https://www.ldraw.org/parts/official-par...rtid=52031

The top curvature and side tapers are exactly the same between the two, but only the width differs (4 stud wide vs 6 stud wide).
According to the file history, Chris made the change of description of 52031 in 2019 and not for 45677.
I think this change would be reasonable:
45677 Slope Brick 45  4 x  4 x  0.667 Double Curved

Moreover, as both of these parts have some substandard (lots of T-junctions, invalid condlines and upper-case references), they need to be reworked in near future. (including splitting top printable surfaces)
