Coordinate System

Cartesian Coordinate System

By default for every command the 1st point will be Cartesian Coordinates

Both coordinates are distance

Polar Coordinate System

2nd point will be Polar Coordinates

One coordinate is distance, another is angle

Polar Angle

By default the angle is Counter-clockwise CCW

Absolute Coordinates

A point start from origin (0,0)
By default the 1st point is absolute coordinates

Relative Coordinates

A point start from the last point
By default the 2nd point onward is relative coordinates
Dynamic Input must be on, the 2nd will automatically detect as relative coordinate
