### 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 |
