[LDPE] 1.8.94 Released (OverlappingSurfacesFinder) - Nils Schmidt - 2025-06-16 Hey, this version gives you a new tool. The OverlappingSurfacesFinder. This tool can find overlapping, touching or intersecting surfaces and T-junctions, too. It supports three scopes: "all surfaces / selection (against all surfaces) / selection (against itself)" The search is relatively fast and efficient, since it uses special data structures to avoid intersection tests against every surface (R*-tree) and multithreading. It is really fast when you use it to test a selection of hundreds of surfaces against itself. Please consider that it can return false positives and negatives, too. As always, you can download LDPE from this page: http://nilsschmidt1337.github.io/ldparteditor/ Changelog: (1 new feature) With this release you will be able to... ...detect overlapping surfaces (with the new OverlappingSurfacesFinder tool). The program was tested intensively with "real world" files. However, something can go wrong in about 140.000 lines of code. Installation on Windows: Download and extract LDPartEditor_win32_x64.zip Run LDPartEditor-1.8.94.msi Start LDPartEditor from the start menu Installation on Linux: Download and extract LDPartEditor_linux_x64.zip Install ldparteditor_1.8.94-1_amd64.deb Start LDPartEditor from the menu or via launcher Installation on Mac OS X: Download and extract LDPartEditor_mac_x64.zip Mount LDPartEditor-1.8.94.dmg Drag LDPartEditor.app to the Applications folder 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.
