[LDPE] 1.9.03 Released (round single vertex / bugfix for "Replace All") - Nils Schmidt - 2026-04-11

Hey,

this release lets you round the coordinates of a single selected vertex directly in the vertex popup window.
It also fixes the critical search and replace bug which was reported by N.W. Perry and improves the new auto-save feature a little bit.

As always, you can download LDPE from this page:

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

Changelog:

(1 new feature and 3 bug fixes)

With this release you will be able to...
  • ...use a "rounding vertex button" on the vertex popup window.

The following critical issues are fixed:

  1. Program freezed on "Replace All" (caused by search and replaces like "b" -> "bb")
  2. A pattern file name "...ps1" was detected as a subfile.
  3. Theoretical problem with auto-save when the editor is not fully initialized yet and a practical problem when auto-save saves the file at the same time as a manual save (simultaneous file access).

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-1.9.03.msi
  3. Start LDPartEditor from the start menu
Installation on Linux:

  1. Download and extract LDPartEditor_linux_x64.zip
  2. Install ldparteditor_1.9.03_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-1.9.03.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. Linux Mint >=22], Mac OS X [>=14]
  • 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. Linux Mint >=22], Mac OS X [>=14]
  • 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.

Brilliant, thanks for the quick turnaround!

Not only is the bug fixed, I can also now append a Z-coordinate (or anything else) to the end of each line in a selection, such as a group of 2D vertices pasted from Inkscape.

(Of course, I realized I can even save a further step by adding the missing coordinate in the X position, in the same step where I add the !LPE VERTEX meta. So I can Find/Replace the SVG lineto commands "L " with the string "0 !LPE VERTEX 0 " and voila! instant 3D vertices.)  Cool

[LDPE] Selected elements rounding - Philippe Hurbain - 2026-05-13

A little quirck with rounding: a vertex that is selected in the 3D view is not rounded when you round a selection in the text window that contain this vertex. Probably related to synch edit

Thanks, Philo. I created a bug ticket (#1200).
