  Need LDPC help
Posted by: Jaco van der Molen - 2019-06-14, 11:58 - Forum: Parts Author Tools - Replies (10)

Hi all,

Recently I dove into LDPC and need some help.
Questions I have:

1. Can I use primitives in patterns?
2. Can I select more then one primitive and copy/paste/duplicate them?
3. Can I group a primitives and triangles and copy/paste/duplicate them?
4. Can I use submodels in patterns?

For example, I am creating the pattern for the laserrelector sticker from set 10266.
It has a repetative pattern of dots.
I made one dot with disc primitives and filled the gaps with triangles.
Now I want to use that dot as many times as needed, create the rows and copy them.

Attached is my work so far.

  Cosmic Comet
Posted by: Lincon - 2019-06-13, 5:20 - Forum: Official Models - Replies (1)

Hello everyone,,,
I'm new here, and just discovered this whole idea of creating digital Lego files and such. That said, I thought I'd at least try my hand at recreating a couple of my old Space Classic kits (especially since the original instructions were starting to fall apart). This is the first one I tried:

6825-1 - Cosmic Comet

I used LDCad 1.5, and then used MPDCenter to check/update for OMR compliance. At least I THINK I did it all correct. If there's something I did incorrectly, mobdro lucky patcher kodi or need to change, don't hesitate to let me know. I'd like to learn on the little ones before I go crazy on some of the bigger models my kids have!

  Add substitute part from context menu
Posted by: tatubias - 2019-06-12, 13:52 - Forum: LDraw File Processing and Conversion - Replies (3)

some days ago i asked trevor to add this to lpub3d now it will be available on 2.3.12 version of lpub3d

Add an option when you right click on the PLI "brick" to add Substitute part, with a dialogue to also change color, scale, camara angels etc.
The aim is to automate the following manually entered meta commands:

0 !LPUB PLI BEGIN SUB 20844c01.dat 15
1 15 -160 -24 20 0 0 1 0 1 0 -1 0 0 powerfunc2distsens-1.ldr
[Image: 68747470733a2f2f6170702e6769746b72616b65...3338623362]
Version of LPub3D - 2.3.12
Operating system - All
Insert, update or remove part substitution meta commands via the PLI part context menu (right-click) with a dialogue to configure the following:
Primary Arguments:
  • Part type,
  • Part colour,
Extended Arguments:
  • Scale
  • Field of View
  • Camera angle latitude
  • Camera angle longitude
  • Part rotation - Using ROTSTEP arguments
NOTE: Extended Arguments are disabled when LDView 'Single Call' render option is enabled. As this option processes multiple part model files simultaneously (i.e. on a single command call), it is not currently possible to individually apply the extended arguments to each part.

  Turntable 2855 accuracy
Posted by: Lincon - 2019-06-12, 8:09 - Forum: Parts Authoring - Replies (3)

Hello everyone,,,
Is the 2855 "Technic Turntable Type 1 Top" known to be inaccurate at all?

I originally abandoned my attempt to position a gear to drive this turntable because it looked like what I was attempting was illegal, but now I think my desired position is fine and it's just an inaccurately defined 2855 part.

The enclosed MLCad screenshot shows the simplest example of the problem. All parts are correctly stud-aligned. But I've raised the red gears to highlight the problem. As you can see, showbox.bio/ tutuapp.uno/ vidmate.vet/ the red gears actually cut into the body of the yellow turntable. I've included close-ups of how much the overlap occurs. I also added the grey gears just to show that no such problem exists between the grey and red gears. The problem is only with the turntable.

Can I safely assume that 8 and 24 tooth gears *can* be positioned as shown?

Lightbulb [LDPatternCreator] Release 1.7.1 (better rotation / usability / triangulation)
Posted by: Nils Schmidt - 2019-06-10, 20:15 - Forum: Parts Author Tools - Replies (24)


today, I decided to finish more features for LDPatternCreator. Here is the result!

Download and install the latest LDPatternCreator release directly from sourceforge.net.

Change log:

New features:

  • Rotation will be applied around the selected vertex which is the nearest to the cursor (except for primitives, subfiles and groups)
  • A click on "Select" cancels "Add vertex" / "Add triangle" ...
  • "Remove isolated vertices" is always visible and enabled on the toolbar
  • "Fast triangulation II" is renamed to "Create new vertices during triangle creation"
  • "Fast triangulation" is now always active by default (can be temporarily deactivated by pressing CTRL or cancelled with RMB)

Fixed bugs:
  • Fast triangulation suggested the wrong edge on longer triangles
  • A rare error occured during triangle creation

As always, I included a short readme.htm in the installation directory.

Cheers & Leg Godt

  [LDPatternCreator] Release 1.7.0 (triangulation improvements and primitive bug-fix)
Posted by: Nils Schmidt - 2019-06-09, 12:28 - Forum: Parts Author Tools - Replies (6)


on Magnus' and Steffen's workstations the "fast triangulation" feature was not working as expected.
I corrected the implementation and now it works better on all machines.

Download and install the latest LDPatternCreator release directly from sourceforge.net.

Change log:

New features:

  • Fast triangulation will now find the nearest edge not the nearest vertex pair. It is also more responsive.
  • Auto-corrections for primitive data when loading a file

Fixed bugs:
  • Fast triangulation did not work on some machines
  • Undo/redo with primitives broke sometimes the stored primitive data

As always, I included a short readme.htm in the installation directory.

Cheers & Leg Godt

Rainbow [LDPartEditor] 0.8.46 Beta Released (https + ldraw.org)
Posted by: Nils Schmidt - 2019-06-08, 9:43 - Forum: Parts Author Tools - No Replies


with this release I replaced the http-interface to ldraw.org (required for the download of ldconfig.ldr and parts from the tracker) with a solution which uses https.

I also provided an alternative 64-bit linux release since I had some problems with LDPE on another linux distro.

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

(1 new feature and 3 bug fixes)

With this release you will be able to...

  • ...see some hints on the configuration screen when you are launching LDPartEditor for the first time.

The following critical issues were fixed:

  1. The PartReview tool got broken by the introduction of HTTPS on the Parts Tracker.
  2. The access to categories.txt and ldconfig.ldr got broken by the introduction of HTTPS on LDraw.org
  3. The program did not really quit when the configuration screen was cancelled.

What will the next release 0.8.47 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.

Anyone interested in offering a MOC for the Wikipedia page? The current one is too dark IMO, and I can't re-render it because the author did not link to the model file or POV-Ray source code.

Ideally, a nice radiosity render. It needs to have a compatible license, too, such as one of the Creative Commons licenses. Please also upload the actual model and POV-Ray source code somewhere people can access them (maybe github?) out of courtesy.

If no one has an alternate suggestion I will use a render of Datsville. It would show off the fact that you can create "BIG" models using LDraw, as opposed to LDD where you run into issues faster. But a radiosity render will take a lot of time. Maybe more time than I have. We'll see after I do some test renders.
