  Some questions about LDCad and LPub3D
Posted by: Anto - 2019-08-04, 14:51 - Forum: LDraw File Processing and Conversion - Replies (12)

Hello everybody!

I have recently started to use LDCad and LPub3D to create building instructions. I read many tutorials and discussions about both softwares, but I still have some questions.


Substitute parts (LPub3D):

I have tried to use the function "Substitute part" to replace universal joints or motors, as these parts has been modified in my modelization and I have 2 different universal joints in a PLI.. I wanted to change a motor with its cable by a motor without cable for examble. The function seems to be very simple to use, but every time I try, the app crashes. Any ideas?


Group/Remove group (LDCad & LPub3D):

I have read that it's possible to use a function called "Group/Remove group" in MLCad, when you want to use a buffer exchange on more than one step. So it's possible to put a straight flex, and then to replace it by the final oriented flex some steps after. But I didn't found how it's possible to do it with LDCad. So is it really possible?


Step numbers (LPub3D):

In LPub3D, the numbers of the steps are not like in the LEGO manuals, the software counts the steps of the main model independently from the steps of the sub models. But I wonder if you have a tip to change this even if I think it's not possible. ^^


PLI and Step number placement "bug"?

Sometimes it's pretty difficult to place all the elements correctly. I would like to have the step number and the PLI at the top left of the assembly image, with the step number at the left bottom of the PLI. But sometimes there is like a "bug", it's impossible to place all the elements correctly. I have tried different setups, but sometimes, as in the example below, when I want "Step number: Left Bottom of the PLI" it is not placed correctly. How is it possible to fix that?

To have the same positions as in the LEGO manuals, what do I need to place relative to what element, and how?

[Image: 48453850246_f5c2733e80_b.jpg]

In the previous page, it worked as I wanted, and I used this:

Code:
0 !LPUB MULTI_STEP STEP_NUMBER PLACEMENT LOCAL BOTTOM LEFT PLI OUTSIDE
0 !LPUB MULTI_STEP PLI PLACEMENT LOCAL TOP_LEFT ASSEM OUTSIDE

But it doesn't work for the page above when I use the same code.
I have even tried to remove all the LPub commands for that page to restart, but I still don't reach to do as I want...

In other steps, I have done this, and it also worked perfectly:
Code:
0 !LPUB MULTI_STEP STEP_NUMBER PLACEMENT LOCAL TOP_LEFT ASSEM OUTSIDE
0 !LPUB MULTI_STEP PLI PLACEMENT LOCAL BOTTOM LEFT PLI OUTSIDE
But it doesn't work for the step above.

Is it possible to place all the elements manually on a Multi step page (using a grid to place them easily)? Actually I can place the Step number, the PLI and the Assembly image manually on a single step page, but not on a Multi step one.


Add captures - Zoom on a part of the model (LPub3D):

I don't know how, but I know it's possible, as in the page 6 you can find in this manual made with LPub3D (Available here - By Trevor Sandy). So I'm asking: how to proceed?


(I'm working with the LDView render and not the Native one)

Any help is welcomed! Big Grin

  Generation of Architecture tiles
Posted by: Philippe Hurbain - 2019-08-02, 18:44 - Forum: Parts Authoring - Replies (2)

As asked for by Orion... here is a quick description of how I generate Architecture name tiles.

- Place in a folder txt2dat.exe tool (I use version 0.2.3)
- place the true type (.ttf) font to use in the same folder (it's simpler than to use the file in Windows font folder). I generally use the ubiquitous Arial font. While the match is not perfect it's OK in most cases.
- Open a command prompt in that folder (there is also a little gui shell, GUItx2d, http://jc-tchang.philohome.com/manuel/tx...tm#guitx2d but for some reason it doesn't work on my machine)
- Key in the command line:

txt2dat -s "Empire State Building" -o empire.dat -l -p 50 -h 80 -c 15 -b 0 Arial.ttf

where
-s "Empire State Building" is the string to generate
-l means don't draw edge lines
-p 50 gives character size. Smaller size may not be detailed enough
-h 80 gives the height of bounding box. Sometimes automatic size result in pattern folding on itself
-c 15 to get white characters
-b 0 on black background
...and the last parameter is the font to use.

Now open the generated file in LDPart editor
- Remove the quads in file (4 sides of the bounding box). The rest of the file should contain only triangles.
- Add the 4162s01 tile 1x8 subpart
- Select text and background and translate by 0.25ldu in y direction (txt2dat creates a sticker so the text is at y=-0.25 ldu, we want it at y=0)
- Scale text appropriately (about 0.27 in x and z directions)
- select background corner vertices (one at a time) and merge them (one at a time) to tile subpart corner vertices (ctrl+e).
- Verify that this operation didn't result in mesh folding on itself (red triangles in BFC mode)
- Save
- Process in datheader to reduce excessive number of digits and to merge triangle to quads.

For txt2dat details see also http://jc-tchang.philohome.com/manuel/txt2dat.htm (in French)

Tell me if you need more details...

  LDCad 1.6c Flex Part Problem with Lpub3D
Posted by: Johann Eisner - 2019-08-01, 18:43 - Forum: LDraw File Processing and Conversion - Replies (6)

It looks like there is a problem with LDCad 1.6c when creating flexible parts.
For example, with flexible axles:
When i open the created file with LPub2.3.6 I got an error message that the file 's / faxle1.dat' can not be found.
The file is contained in both the complete.zip and the unpacked files.
If you open the file with LPub 2.3.12, there are no problems.
Flexible axles created with LDCad 1.6b are no problem, neither in 2.3.6 nor in 2.3.12.
Have attached two test files.

  42093 C Model: Race Truck
Posted by: Matt Walker - 2019-07-31, 2:35 - Forum: MOCs (My Own Creations) - Replies (4)

Hi all,

Wanted to share one of my MOCs. This one is based off the 42093 set.  I've modeled using stand-in pieces for the 42531 fenders as they weren't in the parts library for stud.io. I used Philo's subfiles from the Parts Tracker to assemble a piece in the Studio PartDesigner, but I'm not sure what the etiquette is for posting MOCs with unofficial parts. If it's alright to do that, I'll rev the file and re-release.

https://rebrickable.com/mocs/MOC-25464/C.../#comments

Links to instructions are on this page, which are available in pdf.

Enjoy!

Cheers, Matt

Hi all, 

Found this site while scrounging for part models to do some modeling of my MOCs in Stud.io.  I’m a MAC guy so I suppose I won’t be using LDraw anytime soon, but I’m astounded at the support and community here.  I look forward to working with you all, and thanks for having me.

Cheers,
Matt Walker (aka Cleansupgood)

  [LDPartEditor] 0.8.47 Beta Released (5-digit LDConfig entries)
Posted by: Nils Schmidt - 2019-07-29, 19:28 - Forum: Parts Author Tools - Replies (4)

Hey,

large colour numbers were not compatible with LDPartEditor. It is now corrected.
There is basically no limit anymore (don't try the 32-bit integer maximum Big Grin ).

[Image: imgDuke2.png]
As always, you can download LDPE from this page:
http://nilsschmidt1337.github.io/ldparteditor/

Changelog:
(1 bug fix)

With this release the following critical issue is fixed:

  1. High colour numbers prevent the colour dialog from showing up.

What will the next release 0.8.48 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:

Code:
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.
