| br>Attempting to get some acrylic for a panel cut on ponoko, and when I get to the size list I'm curious if it's going by the dimensions of the svg file, or if it's something else??
for example, the list goes
P1 - 7.1inches x 7.1inches
P2 - 15.1inches x 15.1inches
P3 - 31.1inches x 15.1inches
what are these dimensions relative to? br> br>
