Use Coordinates and Coordinate Systems | 219
3 To extract the next coordinate value, specify a different point at the
prompt for the remaining coordinate values.
For example, if you entered .x in step 1, AutoCAD prompts for the Y and
Z coordinate values.
AutoCAD defines a new point at a location that combines the coordinate
values extracted from the points you specified in steps 2 and 3.
Note Instead of specifying a point in steps 2 or 3, you can enter a numeric
value.
To use coordinate filters to specify a point in 3D
1 At the prompt for a point, enter a coordinate filter (.x, .y, .z, .xy, .xz, or
.yz).
For example, enter .x to specify the X value first.
2 To extract the specified coordinate value(s), specify a point.
For example, if you entered .x in step 1, AutoCAD extracts the X value
from this point.
3 At the prompt for the remaining coordinates, do one of the following:
■ Extract the remaining coordinate values by specifying a point.
■ Enter another coordinate filter and return to step 2.
For example, if you entered .x in step 1, AutoCAD prompts for the Y and
Z coordinate values. Specify a second point to extract the Y and Z coordi-
nates simultaneously or enter .y or .z to specify Y and Z values separately.
AutoCAD defines a new point at a location that combines the coordinate
values extracted from the points specified in steps 2 and 3.
Note Instead of specifying a point in steps 2 or 3, you can enter a numeric
value.
Enter Cylindrical Coordinates
Cylindrical coordinate entry is the 3D equivalent of 2D polar coordinate
entry. It specifies an additional coordinate on an axis that is perpendicular to
the XY plane. A cylindrical coordinate describes a point by its distance in the
XY plane from the UCS origin, its angle from the X axis in the XY plane, and
its Z value. You specify a point using the following syntax:
X<[angle from X axis],Z
