Constructs the angle between the infinite line containing the input line segment and the positive x-axis.
[Visual Basic .NET] Public Function ConstructLine ( _ ByVal inLine As ILine _ ) As Double
[C#] public double ConstructLine ( ILine inLine );
[C++]
HRESULT ConstructLine(
ILine* inLine,
double* outAngle
);
[C++]
Parameters inLine
inLine is a parameter of type ILine outAngle [out, retval] outAngle is a parameter of type double
ConstructLine returns the Angle defined by a given Line input. This is the same Angle returned by the ILine::Angle method. The Angle is displacement of the Line from a baseline through the From Point extending in the positive X direction. The returned angle is the smaller angle with measure between -Pi and Pi.
