You mean their own design software? You are mistaken. Ponoko provides templates of their default material sizes, and that&#x27;s about all that&#x27;s required. Oh, you also need to use the correct color path to indicate between engrave and cut passes.<p>Either way, clearly you&#x27;re already calculating this value for billing, no? Or are you just using laser run-time for the bill, and estimating that based on the user&#x27;s guesstimated path length?
