[LDPE] 1.8.96 Released (new random colour mode / subfile types / PrimGen2 bugfix)

[Nils Schmidt]

Hey,

this release provides a new random colour mode to show subfiles in one random colour.
Just click the random colour mode button again to toggle between the two variants.

You can also specify the type of the subfile now when you are going to create one from the selection in the 3D editor.




As always, you can download LDPE from this page:

Changelog:

(4 new feature and 5 bug fixes)

With this release you will be able to...

• ...use a new random colour mode at subfile level, just click the random colour mode button again (it is also the new default for the PartReview tool).
  
• ...see a hint if the header description misses a tilde "~" on subparts.
  
• ...use a quick-fix option to adjust the name from the header based on the part type.
  
• ...(not able to choose) Physical_Colour anymore. It was removed as a part type qualifier (deprecated since 2019).
  

The following critical issues are fixed:

1. The hint for the part type mismatch was not correct for normal primitives.
   
2. The quick-fix option for the part type mismatch did not detect "...s01.dat" names as a subfile.
   
3. "Create a subpart" did not default to the subpart type or offered a choice when no type can be determined from the target path.
   
4. PrimGen2's "Save As..." button modified the file header.
   
5. [Linux] Automatic calculation of the viewport scale factor did not work and needs to be disabled.
   

The program was tested intensively with "real world" files.
However, something can go wrong in about 140.000 lines of code.

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:

• 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: 150 MB
  

Recommended Requirements:

• Operating System (64bit): Windows 7,8,10,11, 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: 500 MB
  
• For a faster start, LDPartEditor and the LDraw™ library should be installed on an SSD.

What happens after 8.99? 9.00 or 9.01 or 8.99a?

[Hageta]

What happens after 8.99? 9.00 or 9.01 or 8.99a?

8.100?

[Nils Schmidt]

8.100?

I'm not sure.
Well, talking about numbers: LDPE 0.8.0 was released 2015. This year 2025 marks its 10th anniversary :)

I started the development at July 26, 2012, over thirteen years ago.
LDPatternCreator (LPC) is from 2010 and fifteen years in the making (although its quite "feature complete").

[Willy Tschager]

LDPatternCreator (LPC) ... (although its quite "feature complete").

I have a different opinion on that .

I'm not sure.

Well, if there was an 8.01, then there can’t be an 8.100.  But if it was 8.1, 8.2, …, 8.10, then 8.100 is logical… or aren’t you sure about going 9.0?
Anyway, version numbers…  

LDPE 0.8.0 was released 2015. This year 2025 marks its 10th anniversary  

Congratulations!

Is there a Shortcut Key for Hide and Unhide objects in LDPE?

I created an issue (#1180).

[Jack]

Hello, friend. Could you tell me if this software has a user manual? I don’t know how to reduce the number of triangles in the exported model.
