How to rotate a whole map from vertical to horizontal

[Fred19732]

Hi everybody,

I built a house plan in a vertical position.
My question is : how can I do to rotate the whole map from vertical to horizontal without having to rotate each object of the map?

many thanks for your answers

Select all the objects, then group them. Now you can rotate everything in the group at once.

Unfortunately not all object types can be grouped. Luckily there are 2 plugins that can do this work:
- Advanced plan editing plugin
- Home rotator plugin
I encourage to try both of them, the first is more complete, but the second should be a lot easier to use for your use case.
