Parameters

Parameters	Description
pt1	Beginning point of the line
pt2	End point of the line

Description

Finds the angle between a line and the current X axis.

Returns the angle of the line in radians. The acutAngle() function measures the angle from the X axis of the current User Coordinate System (UCS), with the angle increasing in the counterclockwise direction.

This function treats pt1 and pt2 as two-dimensional points. It ignores their Z coordinates, in effect projecting the line onto the current construction plane.
