- All coordinates are in mils (1/1000 or an inch). This is an arbitrary decision. Remember in there is no concept of physical lengths/dimensions in schematics
and symbols (for schematic capture only).
- Origin is in lower left hand corner.
- The size of the coordinate space is unlimited, but it is recommended that all objects stay within (120.0, 90.0) (x, y inches).
- It is generally advisable to have positive x and y coordinates, however, negative coordinates work too, but not recommended.
The following figure shows how the coordinate space is setup:
X axis increases going to the right. Y axis increase going up.
Coordinate system is landscape and corresponds to a sheet of paper turned
on its side.
