Save time and money: The big advantage for digital (PDF) plans is the timely delivery (usually same day, or within 24 hours), as well as incurring no shipping fees, and no customs/duties. If delivery is outside the US, digitals are likely more economical
Convert for CNC: Folks tell us they convert from PDF to AI, and then put into their CAD programs with the idea of creating CNC files.
Change scale: You can print at a reduced scale, so if you are a modelmaker that could be helpfful. If you are building from our half-hull model plans you could change the scale with those, too.
Other considerations: When folks buy these as digitals instead of the print, they typically put the file on a flash drive and take it to a local print shop. Pages are typically 30" x 40". The trade off is having to pay the printer instead of the customs / duties/ taxes and shipping fees. If you are in the US, it's likely cheaper to get the print version.
Scale: You'll see a measurement on pages that have full-sized drawings, so your local print shop will just need to print to that size. Typically just selecting 100% does the trick. You needn't print all pages full size if you want to save money. You would just need certain items (like mold patterns) at full-size.
