IConstructCircularArc2.ConstructTangentRadiusChordEx Method (ArcObjects .NET 10.8 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
Constructs an arc with a common tangent to the input segment, a given radius and a chord length.
[Visual Basic .NET] Public Sub ConstructTangentRadiusChordEx ( _ ByVal Segment As ISegment, _ ByVal atStart As Boolean, _ ByVal isCCW As Boolean, _ ByVal inRadius As Double, _ ByVal chordDistance As Double, _ ByVal IsMinor As Boolean _ )
[C#] public void ConstructTangentRadiusChordEx ( ISegment Segment, bool atStart, bool isCCW, double inRadius, double chordDistance, bool IsMinor );
[C++]
HRESULT ConstructTangentRadiusChordEx(
ISegment* Segment,
VARIANT_BOOL atStart,
VARIANT_BOOL isCCW,
double inRadius,
double chordDistance,
VARIANT_BOOL IsMinor
);
[C++] Parameters Segment
Segment is a parameter of type ISegment* atStart
atStart is a parameter of type bool isCCW
isCCW is a parameter of type bool inRadius
inRadius is a parameter of type double chordDistance
chordDistance is a parameter of type double IsMinor
IsMinor is a parameter of type bool
Please see the ConstructTangentRadiusChord method for more details.
-isCCW stands for "is counter clockwise"
-If IsMinor is true the central angle of the output Arc will be smaller or equal than PI (Approx. 3.14 Rad)
