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 |
