XY plane. Cylindrical coordinates define points by a distance in the XY plane
from the UCS origin, an angle from the X axis in the XY plane, and a Z value.
You specify a point using absolute cylindrical coordinates with the following
syntax:
X<[angle from X axis],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, 5<30,6 indicates a point 5 units from the origin of
the current UCS, 30 degrees from the X axis in the XY plane, and 6 units along
the Z axis.
When you need to define a point based on a previous point rather than the
UCS origin, you can enter relative cylindrical coordinate values with the @
prefix. For example, @4<45,5 specifies a point 4 units in the XY plane from
the last point entered, at an angle of 45 degrees from the positive X direction,
and extending 5 units in the positive Z direction.
To enter relative cylindrical coordinates
■ At a prompt for a point, enter the coordinate values using the following
format:
@x<angle from the X axis,z
For example, @4<60,2 represents a location that is 4 units along the X axis
from the last point measured at 60 degrees from the positive X axis and at 2
units in the positive Z direction.
