LDraw.org 2023-01 Parts Update Now Available |

The 2023-01 LDraw Parts Update has been released. This update adds 121 new files to the core library, including 84 new parts and 9 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 2023-01 here, and download the zip-file update or Windows install package here. Currently LDView download is unavailable due to the new server configuration. This will be fixed in the near future
This update marks the culmination of an almost year long effort to completely rewrite and overhaul the Parts Tracker software. It also marks the shift of the default library license from CC BY 2.0 to CC BY 4.0. Because of both of these, this is a complete reissue of the entire library.
Thank you to all the beta testers and parts authors who gave feedback during the development of the new PT software. This project would not have come together without your help.

A new math puzzle, yay! |

I'm overdue for a math puzzle, I think, so here's one from 10234 Sydney Opera House! I've attached the instructions page I'm working on. I haven't given up yet, but I also haven't figured out the answer, so why not play along?
Basically there's a y-shaped yoke with two technic beams attached, each ending in a ball joint. The ball joints are fixed into two sockets that are 200 LDU apart on center.
The beams are 240 LDU long, from the ball center to the pinhole where they attach to the yoke. (The beam/ball assembly is offset in shape, but because it's pinned to the yoke at a fixed angle, we can simplify by measuring from the ball to a point 20 LDU inboard of where the beam attaches to the yoke.)
The yoke assembly can pivot freely with respect to the beams, so their distance apart at the yoke end is variable (but symmetrical). Because they are pinned to a 135-degree connector, their axes of rotation are each fixed at 22.5 degrees off parallel.
The stem of the yoke (yellow cylinder) rests inside a u-shaped bracket. Importantly, the yoke is NOT pinned to the bracket, so it presumably rests against the inner wall of the bracket but can be at a slight angle, as the instructions suggest. If this is so, then it would pivot around the upper tangent point of the cylinder. The inner surface of the bracket is 200 LDU away horizontally from the ball joints, so the pivot point is fixed there. The top surface of the bracket is 170 LDU vertically away from the ball joints, but the pivot point rests at a non-fixed position that's probably a few LDU lower than the top surface.
I've modeled this in GeoGebra, which you can see here. In this model, point A is adjustable vertically, and point B can be rotated to set the angle of the yoke assembly. Point I is the ball joint, and point F' is the simplified connection point of the beam to the yoke, so it needs to be 240 LDU from point I, indicated by the inner edge of the big purple cylinder. (Point G, and the outer edge of the cylinder, represents the actual connection point of the Technic beam.)
The puzzle is to find the vertical position of A, and the angle of A-B, such that F'-I equals 240 and lies on the inner plane of the big flat cylinder. My hunch is there's only one solution, but that it requires more constraints than GeoGebra can accept. I might be wrong about that, though!

10316 The Lord of the Rings: Rivendell |

Hello, since the digital instructions are out today, I want to build the Rivendell set digitally.
But there are some pieces missing (no critical ones):
(https://www.newelementary.com/2023/02/le...rings.html)
- Plant, w/Plate 2x3x2, No. 1 (Design ID 2682)
- lotsa new Weapons (Axe, Swords, Sting, broken Narsil)
- new headgear and wigs (Gimli Helmet 2675 and Beard 2676, Legolas/Elrond Hair 100953, dual molded, like 10055p01)
- new Heads and Torsos
Edit: not new but still missing: 36806
https://www.bricklink.com/v2/catalog/cat...conly%22:0}
80497 is very similar to 43892, but still new
https://www.bricklink.com/v2/catalog/cat...conly%22:0}
I think I will just build the base without the figures to add them later.

PT Maintenance |

I plan on taking the entire library site down for extended maintenance sometime this weekend. I need to clean up the cruft left over from development and streamline some processes hogging up server memory. Depending on how it goes this could last as little as a few hours or, worse case, both days.
I will update this post if the plan changes.

10299 stickers, please. |

Hello, my name is Dongjin Choi and I am using ldcad in Korea. I want to ask about how to make stickers. I am making a sticker that is not detailed by making a lot of dots on 'Ld Pattern Creator' with the image I received from Google. Is there a way to scan a bitmap image with a dat file? How do other people make amazingly detailed stickers? I would really appreciate it if you could let me know. I request the set number 10299 sticker and how do I make it like the set number 10273 sticker? I have an image.

[LDPE] 1.8.64 Released (rectifier defaults / usability / txt2dat) |

Hey,
this release will provide four small improvements.
![[Image: attachment.php?aid=12753]](https://forums.ldraw.org/attachment.php?aid=12753)
As always, you can download LDPE from this page:
http://nilsschmidt1337.github.io/ldparteditor/
Changelog:
(4 new features)
With this release you will be able to...
- ...benefit from a new Rectifier default setting (it will not convert quad to rect when the quad has adjacent condlines by default (results in smoother surfaces)).
- ...use the "Copy" command on the icon bar at the bottom of the tab, mirrored from the contextual of the "Problems" tab
- ...have a single background bounding rectangle for the whole string (txt2dat).
- ...use an alternative option to not have a background but only the characters themselves (txt2dat).
The program was tested intensively with "real world" files.
However, something can go wrong in about 140.000 lines of code.
Installation on Windows:
- Download and extract LDPartEditor_win32_x64.zip
- Run LDPartEditor-1.8.64.msi
- Start LDPartEditor from the start menu
Installation on Linux:
- Download and extract LDPartEditor_linux_x64.zip
- Install ldparteditor_1.8.64-1_amd64.deb
- Start LDPartEditor from the menu or via launcher
Installation on Mac OS X:
- Download and extract LDPartEditor_mac_x64.zip
- Mount LDPartEditor-1.8.64.dmg
- Drag LDPartEditor.app to the Applications folder
- Copy ldparteditor.sh to your home folder
4a. Open a Terminal.app and run ./ldparteditor.sh
4b. Or open a Terminal.app and run /Applications/LDPartEditor.app/Contents/MacOS/LDPartEditor
I listen carefully to your requests and possible complaints. Please leave me a message, with your thoughts and wishes to further improve the software.
LDPE is a 3D CAD application: The overall system requirements are higher. While I recommend to use a powerful 64-bit multicore system, it could be possible, to run LDPE on older machines as well.
System Requirements:
Minimum System Requirements:
- OpenGL 2.1 compatible Graphics Card
- Operating System (64-bit): Windows [7 or newer], Linux [e.g. Ubuntu Linux >=14.4], Mac OS X [>=10.6]
- CPU: Multicore-Processor e.g. Intel Core 2 Duo or AMD Athlon II (>2.0Ghz)
- RAM: 4GB
- Video-Memory: 1 GB
- Free Disk Space: 100 MB
Recommended Requirements:
- Operating System (64bit): Windows 7,8,10, Linux [e.g. Ubuntu Linux >=14.4], Mac OS X [>=10.6]
- OpenGL 3.3 compatible Graphics Card
- CPU: Multicore-Processor with 4 cores (or more)
- RAM: >4 GB
- Video-Memory: >1 GB
- Free Disk Space: 512 MB
- For a faster start, LDPartEditor and the LDraw™ library should be installed on an SSD.
