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.

  • @x,y

This creates a point located relative to the last point created;
the coordinates are added to the coordinates of the last point created (vector addition).

  • distance<rotation

This creates a point a specified distance from the origin, and rotated a specified amount of degrees around the origin.
The positive x axis is at 0 degrees, the positive y axis is at 90 degrees.

  • @distance<rotation

This creates a point a specified distance from the last point created, and rotated a specified amount of degrees around that point.
