Enter 3D Cartesian Coordinates
3D Cartesian coordinates specify a precise location by using three coordinate
values: X, Y, and Z.
Entering 3D Cartesian coordinate values (X,Y,Z) is similar to entering 2D
coordinate values (X,Y). In addition to specifying X and Y values, you also
specify a Z value using the following format:
X,Y,Z
NOTE For the following examples, it is assumed that dynamic input is turned off
or that the coordinates are entered on the command line. With dynamic input,
you specify absolute coordinates with the
# prefix.
In the illustration below, the coordinate values of 3,2,5 indicates a point 3
units along the positive X axis, 2 units along the positive Y axis, and 5 units
along the positive Z axis.
Use Default Z Values
When you enter coordinates in the format X,Y, the Z value is copied from the
last point you entered. As a result, you can enter one location in the X,Y,Z
format and then enter subsequent locations using the X,Y format with the Z
value remaining constant. For example, if you enter the following coordinates
for a line
