Enter 3D Coordinates (page 139)
Use Dynamic Input (page 144)
Enter 2D Coordinates
Absolute and relative 2D Cartesian and polar coordinates determine precise
locations of objects in a drawing.
Enter Cartesian Coordinates
You can use absolute or relative Cartesian (rectangular) coordinates to locate
points when creating objects.
To use Cartesian coordinates to specify a point, enter an X value and a Y value
separated by a comma (X,Y). The X value is the positive or negative distance,
in units, along the horizontal axis. The Y value is the positive or negative
distance, in units, along the vertical axis.
Absolute coordinates are based on the UCS origin (0,0), which is the
intersection of the X and Y axes. Use absolute coordinates when you know
the precise X and Y values of the point.
With dynamic input, you can specify absolute coordinates with the # prefix.
If you enter coordinates on the command line instead of in the tooltip, the
# prefix is not used. For example, entering #3,4 specifies a point 3 units along
the X axis and 4 units along the Y axis from the UCS origin. For more
information about dynamic input, see
Use Dynamic Input (page 144).
The following example draws a line beginning at an X value of -2, a Y value
of 1, and an endpoint at 3,4. Enter the following in the tooltip:
Command:
line
From point:
#-2,1
To point:
#3,4
The line is located as follows:
