Summary	0004397: Extensions module directory lacking from module paths on startup
Description	Modules installed (by the Extension Manager) in the user Python modules directory %appdata%\FreeCAD\Mod are not accessible by means of the Python console (nor are they available to macros loaded into the workbench) when FreeCAD is started without command line options (e.g. from the start menu after a fresh install). Things work fine when starting with the --module-path option, like `> path\to\FreeCAD.exe -M %appdata%\FreeCAD\Mod`
Steps To Reproduce	This description is pretty arbitrary, but it is what I stumbled across. Get a fresh install of FreeCAD 0.18.4 on Windows 10. Install, by means of the Extension Manager, A2+. This drops a Python module directory A2plus in your %appdata%\FreeCAD\Mod directory. Start FreeCAD (from the Windows Menu, i.e. without command line options). In the Python console, type `>>> import A2plus` The interpreter reports ModuleNotFoundError on A2plus for the line entered. Quit FreeCAD, and restart with the extension modules directory passed as an additional Python module path, e.g. `> & "$env:ProgramFiles\FreeCAD 0.18\bin\FreeCAD.exe" -M "$env:AppData\FreeCAD\Mod"` In FreeCAD, try accessing A2+ from the Python Console again, `>>> import A2plus` The module is now accessible (and can be listed, e.g. dir(A2plus)).

openBrain 2020-07-07 16:22 developer ~0014625	@Fizik : please tell us what you did wrong so everybody will take advantage of this. I'll close ticket when done. Thx.

Fizik 2020-07-07 21:37 reporter ~0014633 Last edited: 2020-07-07 21:38	@openBrain The module is accessible by the name FreeCAD.A2plus (instead of A2plus without the prefix), and hence is imported by `import FreeCAD.A2plus` (I got myself fooled by the — apparently outdated — example file [A2p_animation-example-script.py](https://forum.freecadweb.org/download/file.php?id=97981) from the [A2+ documentation wiki](https://wiki.freecadweb.org/A2plus_Workbench).)

Kunda1 2022-02-04 18:45 administrator ~0016350	@openBrain where should we document this?

openBrain 2022-02-06 17:48 developer ~0016366	@Kunda1 : It's purely related to A2plus so we don't really have room for that. At least the information is here. ;)
