CircularArc3dExtensionGetTangentsTo Method (CircularArc3d, CircularArc3d, TangentType)

Gets the tangents between the active CircularArc3d instance complete circle and another one.

Namespace:  Gile.AutoCAD.Geometry
Assembly:  GeometryExtensions (in GeometryExtensions.dll) Version: 2.0.0.0 (2.0.0.0)
Syntax
Copy
public static LineSegment3d[] GetTangentsTo(
	this CircularArc3d arc,
	CircularArc3d other,
	TangentType flags
)

Parameters

arc
Type: CircularArc3d
The instance to which the method applies.
other
Type: CircularArc3d
The CircularArc2d to which searched for tangents.
flags
Type: Gile.AutoCAD.GeometryTangentType
An enum value specifying which type of tangent is returned.

Return Value

Type: LineSegment3d
An array of LineSegment3d representing the tangents (maybe 2 or 4) or null if there is none.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type CircularArc3d. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Exceptions
ExceptionCondition
Exception eNonCoplanarGeometry is thrown if the objects do not lies on the same plane.
Remarks
Tangents start points are on the object to which this method applies, end points on the one passed as argument. Tangents are always returned in the same order: outer tangents before inner tangents, and for both, the tangent on the left side of the line from this circular arc center to the other one before the other one.
