Hi all,

I'm fairly new to the AEC domain on the 3DEXPERIENCE Platform, so I have some troubles understanding the setup of it all.

One of my main struggles at the moment is how to add new extention sets or editing existing ones. The User Assistance guide is referring to a "Model Specialization Management User Guide: Creating and Editing an Extension", but I am unable to find this anywhere. Does anyone know where this is located?

Secondly, it is also mentioned a "Know-how component" that should be available in the startup folder in the installation. I am not able to find this one either (which probably would solve my problems, if I understand it correctly).

Any help on this topic would be highly appreciated.
