CreateSplineByEqnParams Method (IModelDoc2)

Obsolete. Superseded by ISketchManager::CreateSplineByEqnParams.

.NET Syntax

Visual Basic (Declaration) 
Function CreateSplineByEqnParams( _
   ByVal ParamsIn As System.Object _
) As System.Object
Visual Basic (Usage) 
Dim instance As IModelDoc2
Dim ParamsIn As System.Object
Dim value As System.Object
 
value = instance.CreateSplineByEqnParams(ParamsIn)
C# 
System.object CreateSplineByEqnParams( 
   System.object ParamsIn
)
C++/CLI 
System.Object^ CreateSplineByEqnParams( 
&   System.Object^ ParamsIn
) 

Parameters

ParamsIn

Array containing an array of doubles to use in creating the spline

Return Value

Newly created spline

Remarks

The parameters are provided as three arrays, which for OLE automation are packed into a single SafeArray, which is packed as follows:

[ Dimension, Order, Number of control Points, Periodicity, knot1, knot2,...,ControlPoint1[Dimension], ControlPoint2[Dimension],... ]

Pass the control point coordinates to this routine in sketch space. The Z value is  interpreted as 0. In certain situations, you must transform your B-curve parameters to sketch space using ISketch::ModelToSketchTransform.

NOTE: The curve can be either periodic or non-periodic. If the generated spline is a closed spline, then it must be flagged as periodic. Additionally, splines generated in sketches must be G1 continuous. If the data passed to this method does not generate a G1 continuous spline, then it is rejected and a spline is not created. If your data is not G1 continuous, then you must split the spline into multiple G1 segments and call this method for each segment.

For the OLE interface, you can use the returned object pointer directly to call any APIs on the ISketchSpline interface or its base class, ISketchSegment.

This method does not work with IModelDoc2::SetAddToDB or IModelDoc2::SetDisplayWhenAdded. It always adds the spline directly to the database (as if IModelDoc2::SetAddToDB(True) is in effect), and you must redraw your document window to see the entities that you added (as if IModelDoc2::SetDisplayWhenAdded(false) is in effect).

To create 3D splines, see IModelDoc2::InsertCurveFilePoint and related functions.
