I plan to give FreeCAD AppImage documentation situation one more look, likely February. For now my advice would be to:
Doing it in such way should give you more "stable" path, listed in the pop-up once pressing the F1 key. Move the downloaded documentation to the location, as seen in the pop-up dialog.
Code: Select all
./FreeCAD_0.19.AppImage --appimage-extract ./squashfs-root/AppRun
