Multiple Parts
You can include multiple different parts in one job for 2D designs. For example, you could design a sheet metal box
consisting of two separate pieces in one job. To include multiple designs simply include
each part in the drawing on the same screen. If you receive an error about multiple parts it is usually because your parts do not conform to the 2D part definition. You can also have differing quantities. For example, you could order 10 of one part
and 20 of another. To order 10 of one part and 20 of another include one copy of the first part, two of the second and then order 10 sets.
3D designs permit only one design per order. Orders that split a single 3D design in two using the Air Inside feature are not accepted.
