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 on page 223.
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:
Relative coordinates are based on the last point entered. Use relative
coordinates when you know the location of a point in relation to the previous
point.
To specify relative coordinates, precede the coordinate values with an @ sign.
For example, entering @3,4 specifies a point 3 units along the X axis and 4
units along the Y axis from the last point specified.
