  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.

  LDraw file generation
Posted by: Ed Bardet - 2019-07-29, 15:41 - Forum: General LDraw.org Discussion - Replies (22)

I draw and build a lot of cylindrical structures. The builds turn out good but the drawings are not worth much (IMHO). The cylinders are always made up of two brick segments, a 1x2 brick followed by a 1 round brick, with the second and subsequent rows off set by 1 brick. Pretty standard approach.

I would like to programmatically ( spreadsheet ) develop an LDraw file that has better resolution than I can obtain by tweaking individual bricks in a drawing.

Am studying files that I downloaded of small walls both straight and the same wall curved by a specific number of degrees per segment and am working on how the coordinates are computed. Not as straight forward as I had expected.

I am not a math person so the translation matrices throw me. I was hoping that I could find a way that I could calculate the various values for each row. I was wondering if there was an explanation somewhere of how the translation is done. The actual trig would be wonderful.

One other thing,that I was not able to find, was where do the coordinates refer to. The geometric center of the brick? or someplace else.

It looks like there is no spacing between bricks in the computations. Is that correct?

Any help would be appreciated. If anyone else has tried this please let me know. If this is a Don Quixote situation also let me know.
Thanx,
Ed

  Lpub3D 2.3.13 Native Render
Posted by: Nico71 - 2019-07-24, 8:40 - Forum: LDraw File Processing and Conversion - Replies (30)

Hello everyone,

On the good advice of Philo, I have started to test the new renderer of Lpub3D 2.3.12 and in deed, it is very fast comparing to ldview.

Therefore I have started to work on a new model using this one.

But I have a problem regarding the size of the model, size of the callout and the pli. I have noticed that the scale is not longer use and is replace now by fov camera and distance camera) but I do not understand how to work with it properly.

For my example, I have set :

  • Fov assembly : 20
  • Distance : -270 
  • Native factor : -270 (I have found a topic by Trevor which explain that -270 is A4 scale =1)
  • Fov pli : 30 (I want the part a bit smaller)
  • Distance pli : -270

It works fine on the first step when the model is not too big, for instance : 

[Image: 223E7cZ.png]

But I already noticed that the size of the assembly step by step changes, as the model goes bigger (with more parts), the camera seems to dezooming. You can see it comparing the first step and the 4th, I have not change anything, just add the step. You can see also that the callout is too big, with the same value.

When it becomes to be very complicated is when the model is bigger, for instance on this picture : 

[Image: htbJjsR.png]

The mode is very small and the callout too big. So I want to change that but :

When I change the distance camera (for this step only), I have to put +400 to see the model in the page but the callout comes very very very big, so I change the distance camera for the callout but it did not work (lpub add the meta in the callout but then delete when it is regenerate).

So I change the fov for the callout but it do not work well (it changes the first step but not the second and sometimes make an error : image empty, check the fov to 30 default).

The other problem is when I change the distance camera for the assembly only in the step, when I comes to an other page, and go to the first one, the pli is very big (the whole page). So changing the distance factor is not a very good an reliable way.

I can change the fov on the assembly but I have to put 4 or less which tend to generate error.

So basically I want to set the size of the pli, set the size of the model (like the scale in ldview), by rendering the last step of the whole model. And for the first step when the model is smaller, play with the fov or distance. 

It do not bother me that the camera auto zooming but this is pretty annoying of big step wich is too small and small step with is too big.

Therefore, If you have some clue or way to work with it, please tell me, I only want the proper way to work with it, because I think this new render is very interesting for rendering time. If I have to add meta on each step to have constant size or no problem, I will do. Or if I have a special configuration to do.

The most normal way to work for me, will that the camera not automatically zooming depending of the size of the model, in order the placement of the camera is only set by the fov and the distance, and if I want to zoom to see more or less, using the distance camera, but as I mentioned, it doesn't work like that. There are not many documentation of this new render and how to use.

Nicolas

ps : if you do not see the image, please tell me.

  LDCAD - increase views for parts bins?
Posted by: David Manley - 2019-07-23, 8:31 - Forum: LDraw Editors and Viewers - Replies (4)

Is there any way to increase the number of views for the parts bin in LDCAD? There are currently six views but I could do with more! I tend to find I have 3 or 4 set to some fairly common categories (technic, plates, bricks, tiles) but then use the other two for everything else (e.g. slopes, brackets, hinges, search, model content). I'd love to be able to increase the number of available views to "N" and have the tabs (circled in the image below) appropriately arranged in multiple rows.

Regards,

David
