in our team, only for few users it so happens that even after installing the addons, they don't appear in menu bar.
Please let me know if anyone has come across similar issue and any solution for the same.
Check your Add-on Manager to see they are installed properly and are active.
It should also tell you where the commands are located in the menus.
If they are active and you can't see the commands, it could be you have a custom Work Environment and you need to add them manually or switch to a standard WE.
If it is happening in Archicad 25, I would run the latest update on the affected Archicad again - it typically solves the issue.
