How do I change sheet layers from landscape to portrait

[Hanna N]

I have a number of sheet layers. They are all by default in landscape format as it appears. I want some of the sheet layers to be in portrait.

How do I change this?

From the navigation pallet...

Select the sheets you wish to change, you can pick multiple.

Right click on one of the highlighted sheets

Select "page setup"

In the next dialog that appears, select "print setup"

Change to portrait or landscape and all selected sheets will be updated.

 

You can do similar from Tools -> Organization menu, just remember to hit OK when finished if you do it that way.
