I'm seeking your wise advice on proper file paths (relative or absolute) for the various LDraw tools, and why they don't seem to behave the same between themselves.

In my ldraw folder I have these sub-directories, among others:
p/
parts/
Unofficial/
User/

Unofficial (for uncertified tracker parts) and User (for my own parts) each have their own p/ and parts/ subfolders, so they are both valid ldraw libraries. User also has a number of subfolders for parts authoring projects.

So I'm working on a part in one of those project folders in the User library, and it uses a custom primitive that is also in the User library (obviously in User/p/). To get this primitive to appear in LDPE, I have to give it this path: User\p\48\prim.dat. Some notes:

• User is set at the "parts authoring" folder in LDPE, and Unofficial is set as the "Unofficial" folder (even though they're both unofficial libraries).
  
• LDPE creates its own "ldparteditor-temp-project" folder, which I'm not using (never found the reason to). It's located outside my ldraw folder.
  
• I've used relative paths in LDPE before, but for some reason ..\p\48\prim.dat doesn't work.
  

I need 18 copies of a hollow cylinder with a ring at the end for a particular part that I'm working on. Stud2.dat has the correct dimensions when scaled with an integer. However, the purpose of the stud2 primitive is to standardize the implementation of studs to which other parts can connect. Can I use the stud2 primitive for these hollow cylinders or is it reserved for connectivity-studs only?

hola i have never used pathtruder before

these are the test and the settings but when i hit ok it says nothing happened

have i did something wrong?

   

Hello all aspiring part authors

Have you thought about becoming a part author, but haven't found parts that are easy enough to model?
There are a number of low-hanging fruits (easy parts) you could author. I strongly recommend beginning with authoring parts that you own so you can observe the shapes in detail and do measurements.

* 41759 Duplo Hand Sign
Use 31925s01.dat for the base and handle. The outer diameter of the large circle is 80 LDU. Remember to subfile for patterning.

* 60776/10563 Duplo Container Box 2 x 4 x 2 Door with Handle
Use ddoorhinge2.dat for the hinges and 18816s01.dat for the handle. The door should be 5 LDU thick, 160 LDU wide, and you have to measure the height.

* 18806/60775 Duplo Container Box 2 x 4 x 2 with Open Sides
Use ddoorhinge.dat for the hinge socket.

* 27372 Duplo Disk with Handles
This is in principle an easy part. However, there is currently not a primitive for the handle. One should be created.
The same handle groove can be found on e.g. 46376 fire extinguisher with elaborate handle (2 grooves only), 24806 camera, 35092 milk bottle with handle, and 27383 cup with stud inside.

* 24417 Duplo Dog Sled
There are some curves, but they should be rather easy to figure out. The front handle has three grooves like the disk, but on a longer cylinder.
The same handle groove can be found on e.g. 46376 fire extinguisher with elaborate handle (2 grooves only), 24806 camera, 35092 milk bottle with handle, and 27383 cup with stud inside.

Disclaimer. While these parts were not on the parts tracker at the time of writing this post, they may have been added since. There may be more parts which are easy to model but not listed here.

Do the underside 'hollows' need to be modeled on each of the radiating bars?

They do not appear to have any function and would only add size and complexity to an already complex part.

Here's a proposal to make this rubber part from flexible k0x parts

In the new Slave-1 this part is used to attach the side panels to the structure, streching the part a bit, respectively taking advantage of the flexibility.

All parts are in the ZIP

45590_v2 is the standard one

45590_Test as it is used on the Slave-1

While doing so, I added the slight curve on the part

Hello everyone!
Can someone make the 2 parts from the title?
Thanks in advance.

Hi folks,

I just updated the MLCad.ini file accordingly to the latest LDraw.org parts update 2025-04. The .ini file defines (among other things) the parts available in MLCad's, LEOCad's and Bricksmith's minifigure generator.

Download the file from my website: http://www.holly-wood.it/mlcad/mlcad_ini-en.html

Bye, w.

Ich habe eine Frage, werden die Software wie LeoCad, LD Cad und LDPartEditor tatsächlich aktualisiert, weil ich bemerkt habe, dass in LeoCad die Teile nicht richtig verbunden sind, weil man nicht wirklich etwas bauen kann, man muss die Teile immer entlang der 3 Achsen bewegen, es ist ziemlich umständlich und zeitaufwändig, etwas zu bauen. Und mit LDPartEditor könnte auch etwas Neues entwickelt werden, denn das Programm ist ziemlich verwirrend, wenn man neue Teile entwickeln möchte, man weiß nicht, wo etwas ist.

LDView 4.6 is now available.

You can download this release from the LDView Downloads Page.

The main features of this release are:

• Ability to specify a zip file containing the LDraw library instead of a directory if desired. Point LDView to complete.zip.
  
• Support for https for downloads from ldraw.org.
