  [LDPartEditor] 0.8.49 Beta Released (open files/invert zoom direction/selection info)
Posted by: Nils Schmidt - 2019-10-07, 18:28 - Forum: Parts Author Tools - Replies (7)


with this LDPE release it is possible to open multiple files in one go, invert the mouse wheel zoom direction and there are some other features, too Smile

[Image: imgDuke2.png]
As always, you can download LDPE from this page:

(5 new features and 2 bug fixes)

With this release you will be able to...

  • ...invert the mouse wheel zoom direction (Tools... -> Options... -> Customise Shortkeys).
  • ...open multiple files in one go.
  • ...use a shortcut to reset the manipulator to the origin and world orientation ("R" key).
  • ...see the coordinates of up to 4 selected vertices in the status bar (there is some logic behind their displayed order. The topmost vertex is displayed first.).
  • ...benefit from the automatically deactivation of "Add..." when you focus or select something in the text editor.

The following critical issues were fixed:

  1. The scale tool and other tools displayed the manipulator with "global" coordinates when "local" coordinates were active.
  2. There was a missing comma in the selection info on the status bar.

What will the next release 0.8.50 deliver? clever auto-completion / context menu for the text editor / usability.

The program was tested intensively with "real world" files.
However, it is still a beta version and something can go wrong in about 140.000 lines of code.

Make sure that you choose the right architecture for your OS and Java Virtual Machine (JVM) (64bit or 32bit).
A short guide how to check if a 64bit JVM is installed on your system is located at the bottom of this message.

  1. Download the zip-Archive
  2. Extract the archive content to the location of your choice
  3. On windows, double-click "run.bat" to start LDPE.
  4. On linux/mac, you have to excecute the shell script "run.sh" to start LDPE.
Please note that this software is in the beta stage. Although, this version was tested, there are already known issues  for this release. There is a potential risk of data loss.

You can search for updates if you do the following steps:

  1. On windows, double-click "update.bat" to search for updates.
  2. On linux/mac, you have to excecute the shell script "update.sh".
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:
  • 64-bit Java Runtime Environment (JRE) 1.8
  • 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.
How to check your JVM version (32- or 64-bit):

You can try on the command line:

java -d64 version

If it's not a 64-bit version, you'll get a message that looks like:
This Java instance does not support a 64-bit JVM. Please install the desired version.

  43045 - Hinge Plate 2 x 4 with Pin Hole and 2 Holes - Top
Posted by: Orion Pobursky - 2019-10-05, 1:37 - Forum: Part Requests - Replies (2)

43045 and 43056 are new versions of 98286 and 98285 with 2 holes instead of 3. I would do these myself but I don't have the part so I can't verify how the underside has changed.

  Cliff landscape generator
Posted by: Sylvain Sauvage - 2019-10-03, 21:36 - Forum: All Other Programs. - Replies (5)

Hi all,

thanks to a post on Eurobricks, I remembered I made a script to generate cliff landscape LDraw models a few years back.

It generates models like this one:
[Image: falaise.small.png]
(higher resolution)

So I translated the code to Javascript (for portability) and put it there (licenced under GPL 3+).

You can download the project (e.g. as a zip archive), unpack it and open ldraw_cliff.html in a (recent) browser. 

The algorithms are quite simple so it’s really quick.

Note that it might go all wrong on you depending on the parameters (which aren’t really checked).  It will just produce nothing (but messages in the web console if you have one).

Hope you enjoy it.

  Rotation & angle of universal joint?
Posted by: N. W. Perry - 2019-10-02, 3:36 - Forum: Help - Replies (24)

Since I got such quick and helpful advice on my piston rod question, here is my next challenge: universal joints!

Specifically, how do I work out the compound angles of a double u-joint connection? See the image below, where I need to connect axle A to axle B by using the short connecting axle that's floating nearby.

Here are some parameters:

  • Axle A is oriented parallel the model's Z axis; axle B is oriented at an angle to it. The connector will have to be rotated in both the X and Y directions, but you can't just set one and then the other, because changing either affects both. I'm guessing the 't' word, trigonometry, will come in again here, but because of the compound angle, I'm not sure where to place the triangles.
  • Axles A and B are rotated 22.5 degrees with respect to their longitudinal axes; my assumption is that the U-joint will transmit the same angle to the connector axle, and that while this rotation needs to be accounted for, it won't change the method needed to determine the connector angle.
  • I guess I need to determine the rotation of the U-joint hubs at A and B, around both of their local X and Y axes. Again, my assumption is that the hubs themselves, however they may be rotated, will always remain at the same coordinates in absolute space; that is, they always form the point around which the connector axle is angled at each end.
  • The end of the axle at B may need to be slid downward along its own longitudinal axis in order to correctly intersect the connector axle; this unknown position makes the trigonometry harder to figure out for me.
Of course, I can (and probably will) just download this model from the OMR and steal the answers from there, but again, I'm keen to know the right way to solve these challenges on my own. And I could also probably work it out by iteratively tweaking each angle until everything appears to line up, but I like to know that I've actually calculated it precisely instead of just doing it by eye.

Looking forward to everyone's suggestions!

To say the least - I have something left for the era of steam engines.

Especially these time, where the Art Deco has been founded - although my love belongs to the "Art Nouveau",

... also termed in German as "Jugendstil".

Simple marvellous!

So I built this steam locomotive - so as this "Lady" should look like,  trying to reach a maximum from the real original shape....

..as a relict of those nostalgic "Golden Times".

LDraw delivers some benefits, such as "no Dustcatchers" or "room murdering Vitrines", no Limitations of Brick parts amount or unavailable colors.

Also custom parts, patterns or stickers can be designed without any problem.

Always lovely to begin a new project

So, here it is:

Built in th Year of the Lord 1923 and

highlighted with technical performance-enhancing conversions and with representative paint, this machine was first exhibitioned 1925 in Paris, at

Later Termed  : BR 96

  2340p030 - Help - Primitives breaking in Blender import
Posted by: AdamM - 2019-09-30, 22:44 - Forum: Parts Authoring - Replies (4)

Hi Team,

I've created Tail 2340p030 but the surfaces seem to lose their relationships (?) when imported to Blender using the LDR import plugin.

The part was created using LDPE to create left and right templates for use in LDPC, then patterns created. These left and right patterns where then added to the subfile of 2340s01.


The created part imports into Stud.io correctly but subsequent export/import into Blender seems to break the part apart.


What term/technique have I overlooked or misunderstood?

I've actually created all of the "Canada" series printed bricks and am happy to submit them once this piece is complete.

Thanks in advance.
