3D spherical coordinates
specify a location by a distance from the origin of the current
UCS, an angle from the *X* axis in the *XY* plane, and
an angle from the *XY* plane.

Spherical coordinate entry in 3D is similar
to polar coordinate entry in 2D. You locate a point by specifying
its distance from the origin of the current UCS, its angle from
the *X* axis (in the *XY* plane),
and its angle from the *XY* plane, each angle preceded
by an open angle bracket (<) as in the following format:

*X**<[**angle
from X axis**]<[**angle from XY plane**]*

NoteFor 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 following illustration, 8<60<30
indicates a point 8 units from the origin of the current UCS in
the *XY* plane, 60 degrees from the *X* axis
in the *XY* plane, and 30 degrees up the *Z* axis
from the *XY* plane. 5<45<15 indicates
a point 5 units from the origin, 45 degrees from the *X* axis
in the *XY* plane, and 15 degrees up from
the *XY* plane.

When you need to define a point based on a previous point, enter the relative spherical coordinate values by preceding them with the @ sign.
