MKI_CalcArcAngle (Calculation) New in Version 2016.1

C++ Syntax

double

MKI_CalcArcAngle( 

 MKI_CONST_POINT_REF f_rCenter,

 MKI_CONST_POINT_REF f_rAngle1,

 MKI_CONST_POINT_REF f_rAngle2,

 bool f_fPositive );

Calculates the arc-angle of a circular arc.

Parameters

Center

[MKI_CONST_POINT_REF] Coordinates of the circle's center-point in internal [mm].

Angle1

[MKI_CONST_POINT_REF] Coordinates of the circular arc's start-angle definition point in internal [mm].

Angle2

[MKI_CONST_POINT_REF] Coordinates of the circular arc's end-angle definition point in internal [mm].

Positive

[bool] If true, the arc is drawn in positive direction, i.e. counterclockwise. If false, it is drawn in negative direction, i.e. clockwise.

Return Value

Returns the arc-angle of the circular arc in [rad].

Comment

If you want to calculate the arc's length, simply multiply this function's result with the circle's radius.
