I have a large poster 90x40 that I have designed that I need to split into 3 equal parts (30x40). How do I do this?
One way would be to make a new 3-page file (turn off shuffling in the Pages panel and drag the three pages together into a single spread), then place the original poster page across the three-page spread.
But if you just need to print this on a smaller printer, consider tiling it in the Print dialog.
That worked. Thank you!
