Problem With Editing Referenced Model

LayOut
1

Hi,

had to add some scences in a referenced modell shown in Layout. After refreshing the prereferences all settings where lost, especially scale. Sorry, don’t know how to discribe in english, but it drives me crazy.

In Layout the view is rotated by 90°, but how can I find the right position?
Clicking the viewport it rotates back.

Now this is the way I solved it.

Made a copy of SU file and turned it 90°.
Then I had to update the Reference link.

It’s so easy if you know how to go…
