I'm happy to write a unit test for this if that's what's required.

@kliment @hyarion I'm getting to the crux of why I'll state this issue was partially fixed and not completely fixed from the same root cause [commit](https://github.com/FreeCAD/FreeCAD/commit/8b5a3b1124c06228266b5cc06dceb64db61718cd) from June 2024, see...

> Not sure if it is this issue or [#19336](https://github.com/FreeCAD/FreeCAD/issues/19336). Reopening. Really easy to prove, either open the step file you exported in a text editor and look for `SURFACE_STYLE_TRANSPARENT`...

@hyarion after carrying out some crude debugging tests comparing the default supplied example file `PartDesignExample.FCStd` and the boolean test file `PartDesignExampleFusion.FCStd` I supplied at the top of this issue I...

Quite possibly the regression was introduced when TNP was set to Enabled in May 2024. Last good build I have: ``` OS: Linux Mint 22.1 (X-Cinnamon/cinnamon) Word size of FreeCAD:...

I've at least narrowed down the regression to a week. Good build: ``` OS: Linux Mint 22 (X-Cinnamon/cinnamon) Word size of FreeCAD: 64-bit Version: 0.22.0dev.37928 (Git) AppImage 28th June 2024...

Root cause is https://github.com/FreeCAD/FreeCAD/commit/d9ba737132696f761aeba3bc0f1c03de8aa30df4 the code being removed as it caused a massive performance (minutes instead of seconds) impact loading models see https://github.com/FreeCAD/FreeCAD/issues/14952 So whether there can be a specific...

It's taken me a while of debugging but it appears the shape that actually needs _fixing_ is the Sketch, the Ruled Surface is only doing what it's told so the...

When looking at the output from the similar area of code in 0.21.x it shows that there should be two `Wires` being passed (Sketch Edge1 and Sketch Edge3) but when...

@CalligaroV apologies for the delay, here are the tests that run successfully on 0.21.x with no obscure representations (hence why I've disabled the teardown so you can view the surfaces)...
