LDCad 1.7 Beta 2b (win+linux) - Roland Melkert - 2026-03-15
I've released LDCad 1.7 Beta 2b.
This version fixes three bugs:
- Part snapping not working when using an unpacked library.
- Potential crash during part editing combined with include meta's.
- Potential dead lock (program hangs) during mass file close.
It also includes the latest shadow library as found on github.
As always you can get the latest version at:

Thanks Roland. I use LDCad daily and really appreciate your work on it.

In the new part bin I am missing some parts that were available in previous releases of LDCad:
Category Sorted | Technic | Connectors and Pins
- Technic Axle Pin (3749.dat)
- Technic Axle Pin with Friction with 2L Axle (17651.dat)
- Technic Axle Pin with Friction with 2L Pin (11214.dat)
- Technic Axle Pin without Friction with 2L Axle (65249.dat)
- Technic Axle Pin with Friction (43093.dat)
and some other parts with keyword "axle".

Someone mailed me about this problem just a couple of days ago.
It seems my attempt to declutter has resulted in some unintended excludes.
I will address this in the next version, but you can also fix it yourself thanks to the new part bin filter group editor.
Like so:
While the 'connectors and pins' group is visible in the part bin open its menu and select 'edit'
This will open a dialogue that lets you edit the pbg.
In its rules section add ",axle pin" to the line starting with "keep" so it reads:
keep description axle towball,axle pin
Then click accept, this should readd your missing parts.

This fix worked for me. Thanks!

I cannot get LDCad to load after the first run on Ubuntu 26.04. First I had to install glu. The program starts, asks for the LDraw dir, and then loads the gui. If you exit and then restart, nothing happens. On a lark, I deleted the config folder and the program behaves as it did for the first run (i.e. asks for LDraw dir) and loads the gui.
Log file attached.
P.S. All the links to the previous versions of 1.7 are broken. 1.6 doesn't work since it requires and outdated dependency.

So after the delete of config it did run?
The log shows nothing special.
Sometimes on Linux the OpenGL initialisation fails, but it would still show the gui just all black.
If you start the executable from a command line, it should show extra information.
Currently I compile the Linux versions on Debian 9 for maximum support, but it might be time to compile on something newer.

- If I delete the config folder, the GUI starts (after the license and ldraw folder dialogs). If I close and then reopen, the GUI doesn't start unless I delete the config folder again.
- I do run the program to the command line. That's how I figured out I needed to install glu. However, there are no messages.
- Based on my experience with building LDView for the LDraw server, there are some differences between Debian and Ubuntu.
- I did some experimentaion. The program does run normally if I run as root (e.g. sudo LDCad).

Very weird. Bydefault (without a overiding ldcad.cfg) it will not write or read outside the binairy folder. So the root thing is very weird.
I will need to find the time to get a live version running of your Ubuntu version. Figure out what changed. I'm hoping later this week.
