Quick Reference

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]

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.
