Define location of points

Enter the location of a point by "Absolute" or "Relative" reference (Cartesian coordinates):

  • Absolute (x,y) is the horizontal (x position), vertical (y position) from origin (0,0).
  • Relative (@x,y) is the horizontal (x distance), vertical (y distance) from current or selected point.


Length and Angle: (@l<d) is the distance or length (l) and the angle in degrees from zero (d) from the current or selected point (polar coordinates).


Note that:

Degrees Direction
0 (or 360) is Right
90 is Up
180 is Left
270 is Down
