Keeping work from a form when design is changed
I've been working on a form sent to me by a designer, and being new to this particular aspect, it's taken ages. The form has just been changed slightly and I've been sent the updated version by the designer. As only a couple of small things changed 95% of the elements I've placed on the page could be reused - but when I tried to paste the fields and boxes into the new PDF, they weren't in the correct position, unlike had this been done with a "Paste In Place" in something like InDesign.
What's the best procedure for doing this? Surely I don't have to start from scratch?
