Coordinate system
The coordinate system is based on the SVG specifications.
The x-axis is a horizontal line with increasing values going from left to right and the y-axis is a vertical-line with increasing values going from top to bottom.
Units
The default units are mils. In the future, milimeters will also be supported.
Grid size
The default display grid is 100 x 100 mils.
Angles
Angles in the coordinate system are specified as follows in the example below:
import lib
add label("angle:0")
wire left 500
branch:
wire down 500
add label("angle:90")
branch:
wire left 500
add label("angle:180")
branch:
wire up 500
add label("angle:270")
