This figure shows two examples - one of joining curves and one of joining surfaces.

For the curves, the original is a single physical curve made up of two computational curves. The first part of the original physical curve is colored green, and has its origin on the left with the M direction to the right. The second part is colored blue, and has its origin on the right with the M direction to the left. The result of joining the two curves is colored red, with its origin on the left with the M direction to the right.

For the surfaces, the original is a single physical surface made up of four computational surfaces. The first part of the original physical surface is colored blue, is located in the upper left of the original physical surface, and has its origin in the upper left with the N direction to the right and the M direction down. The remaining computational surfaces making up the original physical surface all have the M and N directions oriented the same as the first computational surface. The result of joining the four surfaces is colored red, with its origin in the upper left, and with the N direction to the right and the M direction down.
