(getangle)

(getcfg)

(getangle [point] [prompt])

Ask the user to specify an angle.

This function prompts the user to enter an angle in the current angle units format, which is returned in radians. If a point (2D first point) is provided, getangle determines the angle between the current zero direction (as set in the ANGBASE variable) and the guide line; the angle increases in the counterclockwise direction.

When transforming the entered angle into radians, getangle ignores the ANGDIR variable and measures counterclockwise, with zero radians being the current setting of ANGBASE.

A prompt may be supplied to request a point or angle from the user.

The user cannot enter another LISP expression in reply to the getangle function.

Examples

Code	Returns
(getangle) [pick point]	Second point: 0.262427
(getangle "Rotation angle: ") [pick point]	Rotation angle: 0.25553
(getangle '(5.0 2.0)) [pick point]	no response 2.1588
(getangle '(1.0 3.5) "Rotation angle: ") [pick point]	Rotation angle: 1.33221

NOTE The getangle function measures the angle from the 0-angle as defined by the Units command. To measure the angle from the absolute x-axis (0 = East), use the getorient function instead.
