To enter a relative coordinate (2D)
At a prompt for a point, enter the coordinate using the following format:
@x,y
■ X represents the distance and direction along the horizontal axis from the
last point entered.
■ Y represents the distance and direction along the vertical axis from the last
point entered.
Enter Polar Coordinates
To enter a polar coordinate, enter a distance and an angle separated by an
angle bracket (<). For example, to specify a point that is at a distance of 1 unit
from the previous point and at an angle of 45 degrees, enter @1<45.
By default, angles increase in the counterclockwise direction and decrease in
the clockwise direction. To move clockwise, enter a negative value for the
angle. For example, entering 1<315 is the same as entering 1<-45. You can
change the angle conventions for the current drawing with
UNITS.
Polar coordinates are either absolute (measured from the origin) or relative
to the previous point. To specify a relative coordinate, precede the coordinate
with an @ sign.
The following example shows a line drawn with polar coordinates using the
default angle direction setting. For more information about angle direction
conventions, see “Start a Drawing from Scratch” on page 78. Pressing
ENTER
at the next To Point prompt ends the command.
The following example shows a line drawn with polar coordinates.
