  [LDPE] 1.8.86 Released (CSG Sphere / CSG bugfix)
Posted by: Nils Schmidt - 2024-08-20, 18:34 - Forum: Parts Author Tools - Replies (3)

Hey,

the new sphere from LDView is now used for LDPartEditor's CSG logic.
Here you see a CSG example:

Code:
0 BFC CERTIFY CCW

0 !LPE CSG_QUALITY 16

0 // SYNTAX 1 0 !LPE [CSG FORM] [ID] [COLOUR] [MATRIX]
0 !LPE CSG_CUBOID    a  4 0 0 0 1 0 0 0 1 0 0 0 1
0 !LPE CSG_ELLIPSOID b  1 0 0 0 1.35 0 0 0 1.35 0 0 0 1.35

0 !LPE CSG_CYLINDER  c  2 0 -1 0 .7 0 0 0 2 0 0 0 .7
0 !LPE CSG_CYLINDER  d  2 -1 0 0 0 2 0 .7 0 0 0 0 .7
0 !LPE CSG_CYLINDER  e  2 0 0 -1 .7 0 0 0 0 .7 0 2 0

0 // SYNTAX 2 0 !LPE [CSG FUNCTION] [ID] [ID2] [ID3]

0 !LPE CSG_UNION c d d
0 !LPE CSG_UNION d e d
0 !LPE CSG_INTERSECTION a b f
0 !LPE CSG_DIFFERENCE f d f

0 // SYNTAX 3 0 !LPE CSG_COMPILE [ID]
0 // Inline the following line to get the triangles from the CSG object "f"
0 !LPE CSG_COMPILE f

[Image: attachment.php?aid=12753]

As always, you can download LDPE from this page:

http://nilsschmidt1337.github.io/ldparteditor/

Changelog:

(2 new features and 1 bug fix)

With this release you will be able to...
  • ...use the sphere mesh from LDView for CSG operations, too (!LPE CSG_ELLIPSOID).
  • ...adjust a unification threshold for the CSG optimizer (0 !LPE CSG_UNIFY_EPSILON 0.1).

The following critical issue is fixed:

  1. !LPE CSG_UNION "consumed" a few triangles. Other triangle defects could still occur, but only with very complex union intersections.

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

Installation on Windows:

  1. Download and extract LDPartEditor_win32_x64.zip
  2. Run LDPartEditor-1.8.86.msi
  3. Start LDPartEditor from the start menu
Installation on Linux:

  1. Download and extract LDPartEditor_linux_x64.zip
  2. Install ldparteditor_1.8.86-1_amd64.deb
  3. Start LDPartEditor from the menu or via launcher
Installation on Mac OS X:

  1. Download and extract LDPartEditor_mac_x64.zip
  2. Mount LDPartEditor-1.8.86.dmg
  3. Drag LDPartEditor.app to the Applications folder
  4. Copy ldparteditor.sh to your home folder
        4a. Open a Terminal.app and run ./ldparteditor.sh
        4b. Or open a Terminal.app and run /Applications/LDPartEditor.app/Contents/MacOS/LDPartEditor

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.

Thumbs Up Error with 44568 (official part) ?
Posted by: Bertrand Lequy - 2024-08-17, 7:46 - Forum: Parts Authoring - Replies (11)

Hi again.

It seems there's an error with 44568. The usage of p\clh6 is not correct since it's symetrical and the two fingers are not on this part.

I have this part on my desk right now and I see the same that's shown on this picture :
[Image: 6276045.jpg]

Does it exist two versions of this part, one with symetrical fingers and one without ?

  [LDPE] 1.8.85 Released (primitive substitution / 3D grid intersections /better icons)
Posted by: Nils Schmidt - 2024-08-16, 18:02 - Forum: Parts Author Tools - Replies (6)

Hey,

this release adds primitive substitution to LDPE. It is very similar to LDView's primitive substitution.
I even used some code from LDView and mentioned Travis Cobbs and Peter Bartfai in the credits :)
It also delivers better icons for the dark mode and enhances the 3D grid visualisation.

[Image: attachment.php?aid=12753]

As always, you can download LDPE from this page:

http://nilsschmidt1337.github.io/ldparteditor/

Changelog:

(4 new features and 2 bug fixes)

With this release you will be able to...

  • ...use primitive substitution (blue circle button at the upper left corner, ctrl-click to modify substitution quality).
  • ...benefit from a 3D grid that shows 3D model intersections and has a lager size.
  • ...benefit from inverted icons for a better contrast with dark buttons.
  • ...create a coplanar quad within the "Coplanarity Heatmap" mode.

The following critical issues are fixed:

  1. PartReview had loading problems under MacOS (the 3D view was gone).
  2. (Linux/Mac) case-sensitivity when following a reference from the text editor with a mouse click when the target file was already opened caused problems.

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

Installation on Windows:

  1. Download and extract LDPartEditor_win32_x64.zip
  2. Run LDPartEditor-1.8.85.msi
  3. Start LDPartEditor from the start menu
Installation on Linux:

  1. Download and extract LDPartEditor_linux_x64.zip
  2. Install ldparteditor_1.8.85-1_amd64.deb

  Correction of a offical Part
Posted by: Manfred Schaefer - 2024-08-16, 11:43 - Forum: General LDraw.org Discussion - Replies (2)

Hello,

on the figure head 3626bp41 the moustache is a bit too high, see the following picture (source: Rebrickable).


.png   Bildschirmfoto vom 2024-08-16 13-34-13.png (Size: 108.59 KB / Downloads: 41)

Please also insert the Bricklink reference 3626bpx120.
This head is used e.g. in the sets 6009, 6057, 6086.
Can someone please make this adjustment.
Thanks.

Greetings

  Naming of minifig torsos
Posted by: Manfred Schaefer - 2024-08-15, 17:53 - Forum: Parts Tracker Discussion - Replies (5)

Hello,

There are several minifigure torsos on the part tracker (76382). These are so-called shortcuts. The numbering is 76382pccc, where ccc stands for the printing.
Shouldn't c01 be added as it is a shortcut and there can be several versions, e.g. different color of the arms?

Greetings

Manfred

Thumbs Up Wrong Bricklink reference
Posted by: Manfred Schaefer - 2024-08-15, 17:15 - Forum: Parts Tracker Discussion - Replies (3)

Hello,

I have noticed that the Bricklink reference for the printed official part 98138p0k is incorrect. The reference is 98138pb204 and correct is 98138pb086.
The following pictures should show the error. Note the position of the lens. One time it is off center, the other time it is centered.

   

I would like to correct this error using the “Fast Track” function. But this is not possible for me. Are only certain people allowed to use this function? 
I would send the modified file to the administrator, if that is okay?

There are many other printed official parts where the Bricklink reference is missing. For these parts I would like to specify this reference and a reference to one to three sets. I would also do this using the “Fast Track” function. Alternatively, I can send the changed files to the administrator.
How are these files checked if they have been uploaded to the part tracker via the “Fast Track” function or the administrator. I would only adjust the KEYWORDS and HISTORY lines and cannot judge whether the graphic is error-free. If there were an overlap or a gap here, for example, I would not be able to correct it due to a lack of experience.
What would happen then?

Greetings

Manfred

Edit:

Is this the function for the Fast Track, F at the end of the status in the Parts Tracker?

  Problem with 2792 (incomplete official part?)
Posted by: Bertrand Lequy - 2024-08-12, 16:00 - Forum: Parts Authoring - Replies (5)

Hi, I've a question about 2792.
I had this part as a kid and I remember that there was a "tooth" in the middle of the part, locking 2791a in given position. But on the LDraw part there's nothing.
You can see the "tooth" here (RB picture) :
[Image: 2792-0-f7f89223-6210-47b4-b2b4-4776fca0a5c8.jpg]
My question is : did it exist two versions ofthis part, or is the LDraw version false ?

I search on BL and I got the same part with the tooth :
