# About Entering 3D Spherical Coordinates

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

You specify a point using the following syntax:

X < angle from X axis < angle from XY plane

In the illustration below, dynamic input is turned off, so 5<45<15 indicates a point
5 units from the UCS origin in the XY plane, 45 degrees from the positive X axis in the XY plane, and 15 degrees up from the XY plane. ## Absolute and Relative Spherical Coordinates

You can enter absolute coordinates, which are based on the UCS origin, or you can
enter relative coordinates, which are based on the last point entered.

• By default, when you enter coordinates in the cursor tooltip with dynamic input turned
on (F12), you specify relative coordinates with no prefix, and absolute coordinates
with the # prefix. For example, 5<45<15 specifies a point relative to the previous point.
• If you turn off dynamic input, you specify relative coordinates with the @ sign as
a prefix and no prefix to enter absolute coordinates. In this case, @5<45<15 specifies
a point relative to the previous point.
