Dear all. I have a group who’s red and green axis are at 45° to the ones of the model they’re part of. How do set them to the model axis! Thanks!
If it’s really a group, open the group for editing, right click on an axis line and select Place. Click where you want the origin to be, then along where you want the red axis followed by where you want the gree axis.

If it was a component you could right click on the component and choose Change Axes.
Thanks, that works!
Good enough.
Also note that you could orient the axes correctly during creation if you make components instead of groups.
