Arc.ClosestPoint Method

RhinoCommon API

ArcClosestPoint Method

Computes the point on an arc that is closest to a test point.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)

Syntax

public Point3d ClosestPoint(
	Point3d testPoint
)

Public Function ClosestPoint ( 
	testPoint As Point3d
) As Point3d

Parameters

testPoint: Type: Rhino.GeometryPoint3d
Point to get close to.

Return Value

Type: Point3d
The point on the arc that is closest to testPoint. If testPoint is the center of the arc, then the starting point of the arc is returned. UnsetPoint on failure.
