I was trying to troubleshoot why views created in TechDraw would refuse to show hidden lines, even when I set the "Hard Hidden" and "Smooth Hidden" properties of TD views to true.
Starting from a fresh .FreeCAD folder, I load TechDraw then I go to Edit --> Preferences --> TechDraw. What I see is this: So Hidden Line type is set to "Solide" (Solid) by default. Which seems odd to me.
But, before changing this setting, I go to General then switches the language to English; then I go back to TechDraw. And now, here's what it shows: Uh. It's now set to "NeverShow", and I never touched it.
So I change it to "Dash", click Apply, then switch back to General, change language back to French, Apply, go back to TechDraw prefs, and now the setting is... "ToujoursCacher", which is NeverShow!
