I still prefer MLCad because I am extremely familiar with the XY/YZ/XZ/Preview format which I grew up with developing Quake levels as a teenager.  I know it is pretty dated software, but I was wondering if anyone has reached out to the developer to see if they are open to releasing the sourcecode.

I am not a professsional developer, but I suspect that it would be possible to recompile an x64 and/or ARM build with minimal changes if the source code were available.  I also expect that some of the worst performance bottlenecks (ex: loading the "Select Part" dialog) could be addressed with minor coding optimizations, such as keeping the partlist in memory, or optimizing the code to make use of multithreaded CPU's.

Has this been explored in the past? Is anyone else interested in helping?

Sincerely,

"If the part has studs, the origin shall be the bottom of the topmost stud group."
"If a part doesn't have studs, the origin shall be the bottom of the part."

Despite the docs being very clear about the height of the origin, there are a number of exceptions.

Double curved top:
Official part 31213b has the origin at the top of the part. Sadly, the part was recently edited to correct for orientation. Since the origin height is a multiple of 48, moving the origin to 0 yields no benefit.
Official part 3664 has the origin at 24 LDU. This part should be rotated. The height can be corrected at the same time.

Bases of some kind:
Official part 13358 has the origin at 24 LDU. This was considered tolerable due to the snapping hole.

Official part 92005 has the origin at 24 LDU. The part has a snapping stud.
Official part 92011 has the origin at 48 LDU. The part has a snapping stud.
Parts 13358, 92005, and 92011 have the origin at a height which is a multiple of 24 (Duplo plate height), thus yielding no benefit from moving the origin to 0.
Official part 6405 has the origin at 16 LDU where the base is. This part should be rotated. The height can be corrected at the same time. ...or keep as is (see argument below)

Other:
Official part 4913 has the origin at 16 LDU where the base is.
Official part 4375 has the origin at 16 LDU where the base is.
Official part 4894 has the origin at 16 LDU where the base is.
Parts 4913, 4375, and 4894 have a base at 16 LDU, which could be used as an argument for not needing correction. Placing these parts would always be challenging (not a multiple of 24).
Official part 15327 (shower) has the origin at 16 LDU.
Official part 51708 (flagpole) has the origin at 16 LDU.
Official part 31925 (flag) has the origin at the bottom despite having a stud. This part is on the tracker for another reason.

There are four parts on the tracker with a hold. They have their origin at the bottom, thus following the docs.

I suggest we edit 3664 (needs to be edited anyway), keep 6405, 4913, 4375, and 4894 as they are until they are edited for another reason, and change the origin height of 15327 and 51708 as b replacement versions, and update the origin height of 31925 to the bottom of the top stud. Is this ok?

Willy Tschager observed that parts 2205 and 2208 linked below have their origin at the top and their hinges on the left, while all other duplo doors have their origin in the middle and their hinges on the right.

According to Willy, "This has to be sorted out and Movedto if necessary."
Is it necessary?

The Phase 2 Clone Trooper helmet part is already available in the library, but it’s missing key texture variants like the 501st and 212th legions. Since these are some of the most iconic designs in LEGO Star Wars, it would be amazing to have official decal/textured versions of them for digital builds.

I (and likely many others) would love to see more variety added to this part — especially since only the plain white version is currently available. Any chance we could get these textures added in a future update? Also, where could I find textures or even these helmets if they are not available here?

Hello,

Thanks again for creating my previous requested parts.

I'd like to request Friends Chameleon for Friends OMR project.

I've found a raw mesh in digital-bricks
http://www.digital-bricks.de/en/index.ph...part=15678
but clean-up and split patternable surfaces would be highly appreciated.
I'll try to make printed patterns, so the part body is sufficient.

Thanks in advance,

I'm starting an overhaul of our documentation. Since my time is limited, this will not be a short process.

I have a couple of goals:
- Convert all the documentation from its current dependency on a specific component style library to GitHub Flavored Markdown (GFM)
- Streamline the current library standards into some more beginner friendly.

I've started a new GitHub repo for our documentation so that we can have better revision history and tracking.

Here's a preview:
https://library.ldraw.org/documentation/3

Note, the above is a very rough first go. My thought process is to have all the requirements highlighted. Right now that's in bold but that style is easily changed if someone have a better idea.

As always, I welcome any and all feedback.

Found here:

- Reformatted for clarity.
- Explicitly stated orientation 
- Added optional suffix to naming convention for non-square/rectangular boxes.

The User Dashboard - 'My Submits' sorting options are 'Filename', 'Description', and 'Status'. My actions such as submission of corrected files do not show up on the User Dashboard - 'Events On My Submits'.
Is it possible to add 'Date' to the former or my actions to the latter?

Hello there people from Ldraw! I'm in need of 2 parts for a big project. Could someone please add these to the parts list? They are both on the builders app I believe
