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.
Enter Spherical Coordinates
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]
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 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.
