SilhouetteComputeDraftCurve Method (GeometryBase, Double, Vector3d, Double, Double, CancellationToken)

public static Silhouette[] ComputeDraftCurve(
	GeometryBase geometry,
	double draftAngle,
	Vector3d pullDirection,
	double tolerance,
	double angleToleranceRadians,
	CancellationToken cancelToken
)

Public Shared Function ComputeDraftCurve ( 
	geometry As GeometryBase,
	draftAngle As Double,
	pullDirection As Vector3d,
	tolerance As Double,
	angleToleranceRadians As Double,
	cancelToken As CancellationToken
) As Silhouette()

Parameters

geometry

Type: Rhino.GeometryGeometryBase
Geometry whose silhouettes need to be computed. Can be Brep, BrepFace, Mesh, or Extrusion.

draftAngle

Type: SystemDouble
The draft angle in radians. Draft angle can be a positive or negative value.

pullDirection

Type: Rhino.GeometryVector3d
3d direction for the mold to be pulled in, directed away from the object.

tolerance

Type: SystemDouble
Tolerance to use for determining projecting relationships. Surfaces and curves that are closer than tolerance, may be treated as projecting. When in doubt use RhinoDoc.ModelAbsoluteTolerance.

angleToleranceRadians

Type: SystemDouble
Angular tolerance to use for determining projecting relationships. A surface normal N that satisfies N o cameraDirection < Sin(angleToleranceRadians) may be considered projecting. When in doubt use RhinoDoc.ModelAngleToleranceRadians.

cancelToken

Type: System.ThreadingCancellationToken
Computation cancellation token.
