Changing template or sheet size

Hello

Would anyone have advice on changing a template or sheet size in an already active document? I’m trying to create an irrigation plan to scale, but want to increase sheet size from 11x17 to 18x24. Thanks

Just go to File>Document Setup>Paper and change the size. The content on the page will appear to be in the upper left corner of the sheet so you’ll need to move and adjust things to suit.

Finally getting back to you to say thanks for info on this question.

You’re quite welcome. I hope it helped.
