Commands: po, point
Specify location
Click in the drawing area or use the following syntax with the command line:
- x,y
- This creates a point at coordinates x,y relative to the origin (0,0).
- @x,y
- This creates a point a specified distance from the relative zero position.
- The @ symbol means that we want the "relative zero position" to be considered the origin;
- the coordinates are added to the coordinates of the relative zero position.
- distance<rotation
- This creates a point a specified distance from the origin,
- and rotated a specified amount of degrees around the origin.
- @distance<rotation
- This creates a point a specified distance from the relative zero position,
- and rotated a specified amount of degrees around that point.
You can read Coordinate system for more information.
