Please vote on adding the following clarifications to the LDraw.org Official Parts Library Specifications. The quoted text would be added verbatim.


Clarification to Sticker Geometry:

Quote:For stickers printed on a transparent medium, the type 1, 3, and 4 lines that comprise the pattern shall be preceded by a 0 BFC NOCLIP statement. If there is non-pattern geometry after the pattern geometry, the pattern geometry shall be ended by a 0 BFC CLIP statement.

The sticker should be oriented such that the top of the pattern aligns with the +Z axis. Exceptions to this rule may be made on a case by case basis.

Quote:All stickers and sticker shortcuts should, at a minimum, include at least one !KEYWORDS entry in the form of Set <set number> where <set number> is the number of an official LEGO set in which that sticker appears. Only one set need be listed, but more may be if desired.

Since !DATA was added to the MPD spec, it turns out to be quite hard to track down. If you look at the Documentation page, it isn't mentioned, so unless you know in advance that it is in the MPD spec, it's hidden. (And since "data" is so generic, a Google search for LDraw data doesn't even include the MPD spec on the first page of results.)

I would suggest adding a parenthetical to the MPD link indicating that !DATA is included there.

I made a dae file of a Bionicle MOC I had made on Stud.io. It does not show up on LDraw when I try to import it but instead crashes it. Is there any reason for that? I want to turn my MOC into a 3D model but I don't know if I can because it keep crashing LDraw. Any help you can give?

Hi,

I am rendering Lego parts using Blender and https://github.com/TobyLobster/ImportLDraw (using "p" "48" ldraw geometries).
Some of the very basic and simple parts take forever to render, and other parts contain artefacts.
Is there a good place to raise a list of parts that are unnecessarily complex or that display render artefacts?

Examples of parts that render extremely slowly (20x slower than complex parts), some of which are the most basic bricks and plates.

Examples of bricks with artefacts:

• many domed bricks
  
• some bricks that have clearly been assembled from subparts with noticeable gaps/ discontinuities
  

Hi. I'm an occasional visitor to this site; pardon me if this question has been addressed elsewhere. I can't find it. I've just started to figure out how to use the keyboard entry method of positioning a part as well as how to set a custom rotation point. (It took me a while to figure out that the Rotation Point tool is universal and not specific to the part! Oh well. I can deal with that.   )

There seem to be three preset grid settings. I might have the angles wrong but let's say they correspond to 90, 45, and 30 degrees. Is there a way to rotate a part to any angle I choose?

Just wondering... I have some custom part files and I have added connectivity and conflict information in Stud.io by using part designer. Is there any way I could import that connectivity of these custom parts but in LDCad? 

Any help would be appreciated.

It seems more common now that different SKU numbers are used for sticker sheets in US sets vs. RoW sets.

For example, these two appear equivalent:
134071A / 24744 / 6142623 at Bricklink: https://www.bricklink.com/v2/catalog/cat...75870stk01
140413A / 24743 / 6142622 at Brickowl: https://www.brickowl.com/catalog/lego-st...4743-24744

Should we create aliases for all 23 stickers 6142623a => 6142622a, etc., or is this overkill? How else might a user know that the stickers for 6142623 already exist in the library as 6142622?

We have done this for older stickers where the design appears on multiple sheets, e.g. 003437b.dat => 003340a.dat.

Just wanted to show/share the very first working interactive animation inside LDCad 1.7 Alpha 2

https://youtu.be/el74hHfufP4

I've been wanting to do this kind of thing for awhile now, it motivated the 1.7 version, so I'm very happy with it

Any comments, ideas for animations etc are welcome.

This is kind of a usability feature for people getting unofficial parts from the PT.

Right now the way to do this is:

• Either a download of the entire unofficial lib
  - slow
  - huge
  - manual transfer to Stud.io+ no need to worry about forgotten subfiles or prims
• Or manually download them one by one and the necessary subfile
  - subfile/new prim might get overlooked
  - tedious to go through all the required files
  - manual transfer to Stud.io
  + small in size/bandwidth
  
• Use the LDView update feature
  + small in bandwidth+ quick- manual transfer to Stud.io

Why don't I see the LDraw logo on top of the pages anymore?
