X & Y Codes
The X & Y values in the Gerber file
determine where the aperture shape and dimension will be
positioned and drawn. X & Y values are used as
coordinate pairs to determine where the light will be
exposed, using the D codes shapes (i.e. D10) and light
exposure status (i.e. D01, D02, D03) for drawing lines
and arcs, as well as moving between drawing entities.
Here are a few examples of using X & Y codes with D codes.

| Step 1 |
D10* |
Select aperture D10 |
| Step 2 |
X1000Y1000D02* |
The D02 tells us that the light will
be off, and we move to coordinate position
X1000 and Y1000
|
| Step 3 |
X2000Y3000D01* |
The D01 tells us that we will draw (light on)
to coordinate position X2000 and Y3000
|
| Step 4 |
X5500Y100D03* |
The D03 tells us to move to coordinate position
X5500 and Y100 with the light off, then flash
(turn the light on and off)
