We had a similar discussion before. The question is, were is the format on the screen? Is there room for punch holes looking at the extent of the drawing in Creo? If in fact you are scaling the drawing to fit it on a page with CutePDF, then the only option is to; a) resize your formats sheets or b) use a custom page size where the format looks smaller but is still to scale.
Welcomee to the forum, Mathieu!
