SketchControlPointSpline3D Object

Derived from: SketchEntity3D Object

Description

The SketchControlPointSpline3D object represents a control point spline within a 3D sketch. These splines are created by defining the vertices of a control polygon of a NURBS curve. The properties and methods listed below are in addition to those supported by the SketchEntity3D object.

Methods

Name	Description
ConvertToSpline	Method that inserts a new control point into the existing control point spline.
Delete	Method that deletes the sketch entity.
GetReferenceKey	Method that generates and returns the reference key for this entity.
InsertKnot	Method that inserts a knot into the existing control point spline. The effect of this will be that the shape of the curve is maintained, but the control polygon will change shape and one additional point will be added.

Properties

Name	Description
Application	Returns the top-level parent application object. When used the context of Inventor, an Application object is returned. When used in the context of Apprentice, an ApprenticeServer object is returned.
AttributeSets	Property that returns the AttributeSets collection object associated with this object.
Constraints3D	Property that returns a collection of sketch constraints that are tied directly to this entity. This collection consists of geometric and bend constraints.
ConstraintStatus	Property that returns an enum indicating the constraint status of the sketch entity, signifying whether it is fully constrained, over constrained, or under constrained.
Construction	Gets / sets the Sketch3D Construction Property.
ControlPoint	Read-only property that returns the SketchPoint3D at the specified index. The indices correspond to the control points in order from the start to the end of the spline. The ControlPointCount property returns the total number of control points for the spline. Deleting the returned sketch point will delete the control point from the spline.
ControlPointCount	Read-only property that returns the number of control points defining the control point spline.
ControlPolygonSide	Read-only property that returns the SketchLine3D object that represents a side of the control polygon. The indices correspond to the control polygon edges in order from the start to the end of the spline.
CurvatureDisplay	Specifies whether curvature information is displayed for the spline.
EndSketchPoint	Read-only property that returns the sketch point that defines the position of the end of the spline.
Geometry	Read-only property that gets a BSplineCurve2d geometry object. The object returned represents a 'snapshot' view of the current state of the spline.
HasReferenceComponent	Property that specifies if the object was created as the result of a derived part.
IsClosed	Read-only property that returns whether the curve is closed.
Length	Gets the length of the entity in centimeters.
OwnedBy	Property indicating entity or entities that own this object.
Parent	Property that returns the parent sketch of the entity.
RangeBox	Property that returns a Box object which contains the opposing points of a rectangular box that is guaranteed to enclose this object.
Reference	Gets and sets whether this entity is a reference entity or not.
ReferenceComponent	Property that returns the ReferenceComponent that resulted in the creation of this feature.
ReferencedEntity	Property that returns the object this entity is dependent on. When sketch entities are created by projecting model edges or intersecting the model, the resulting entities are driven by the original model entities and cannot be modified. This property returns the model entity the sketch entity is dependent on. The Reference property indicates whether the sketch entity is driven by a model entity or not. If the sketch entity is not referencing a model entity, this property will return Nothing. This property can also return nothing even when the sketch entity is referencing a model entity in the case where the model entity has been consumed by some subsequent modeling operation.
StartSketchPoint	Returns the sketch point that defines the position of the start of the spline.
Type	Returns an ObjectTypeEnum indicating this object's type.
