Hi,
this version gives you just a pair of 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:
(1 new feature and 1 bug fix)
With this release you will be able to...
- ...see a hint if the part type does not match to its name.
The following critical issue is fixed:
- A recurring subpart reference loop can cause the program to crash or hang.
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-1.8.95.msi
- Start LDPartEditor from the start menu
Installation on Linux:
- Download and extract LDPartEditor_linux_x64.zip
- Install ldparteditor_1.8.95-1_amd64.deb
- Start LDPartEditor from the menu or via launcher
Installation on Mac OS X:
- Download and extract LDPartEditor_mac_x64.zip
- Mount LDPartEditor-1.8.95.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: 150 MB
Recommended Requirements:
- Operating System (64bit): Windows 7,8,10,11, 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: 500 MB
- For a faster start, LDPartEditor and the LDraw™ library should be installed on an SSD.

Duplo cannon ball part naming |
Posted by: Peter Blomberg - 2025-07-25, 16:45 - Forum: Parts Authoring

BrickLink lists two duplo cannon balls:
54043 Duplo Cannon Ball 1/2 with Large Axle Connector
54043b Duplo Cannon Ball 1/2 with Large Axle Connector and 4 Holes in Top
These parts have visibly different geometry, the newer is more reinforced and has 4 holes.
How should they be numbered in LDraw? Keep 54043 and 54043b or go with a and b versions?

Inverse tang |

I've long struggled with parts that have two curved edges close to each other, but not having the same point of origin. The task is to fill in the area between the curves.
If the curves are far enough apart, I can use tndis and chords. However, if they are close, then I'd have to rotate chords and tndises, which isn't ideal.
Luckily, we have tang for the inside (in yellow). This eliminates the need to rotate ndises, but effectively doubles the number of points. If the inside and the outside of an area to be filled have significantly different number of points, then the result is a large amount of extremely narrow triangles, so this is to be avoided.
What if we had an inverse tang (in black) to be used for the outside? With an equal number of points, it is easy to fill the light gray area with quads.

Possible duplicate faces in some part files |

Hi all,
I think I found some duplicate triangles and quads in some part files. Here are the ones I've managed to identify so far:
- Line 84 in 18922.dat
- Line 26 in 99781.dat
- Line 17 in 2630k02.dat
From what I can tell, removing these lines should have no effect on the geometry other than removing the duplicate faces.
I’m new to LDraw, so please let me know if I’m overlooking any conventions or reasons these might be intentional.
Thanks!

An updated version of the LDraw All-In-One-Installer, in short AIOI, containing the LDraw Parts Library Updates from 2025-02 to 2025-06.
The AIOI supports Windows XP (Home and Pro), Windows Vista or higher (all versions). There are two installer files available: Use the 64 Bit AIOI to install all the main 64 Bit programs, while the older 32 Bit programs are offered in a separated .exe file. Please note that only the 64 Bit version contains the LDraw Parts Library. If you want to use the 32 Bit programs, it is mandatory that the library has been installed previously. The Installer will NOT run on Windows 95, 98, ME, NT Ver 4, 2000, or XP below SP2.
It contains the following changes:
* Update to Parts Library 2025-06
* Update to MLCad.ini 2025-06
* Update to Offline Parts Catalog 2025-06
You can download the AIOI from:
LDraw.org >> Help >> Get Started >> Windows >> LDraw All-In-One-Installer
Many thanks to all the programmers who contributed to this release.
