SketchSplineByEqnParams2 Method (IModelDoc2)

Obsolete. Superseded by ISketchManager::CreateSplineByEqnParams.

.NET Syntax

Visual Basic (Declaration) 
Function SketchSplineByEqnParams2( _
   ByVal ParamsIn As System.Object _
) As System.Boolean
Visual Basic (Usage) 
Dim instance As IModelDoc2
Dim ParamsIn As System.Object
Dim value As System.Boolean
value = instance.SketchSplineByEqnParams2(ParamsIn)
System.bool SketchSplineByEqnParams2( 
   System.object ParamsIn
System.bool SketchSplineByEqnParams2( 
&   System.Object^ ParamsIn


Array containing an array of doubles (see Remarks)

Return Value

True if created successfully, false if not



The parameters are provided as 3 arrays, which for OLE automation are packed into a single SafeArray packed as follows:

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

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

NOTE: If the spline being generated is a closed spline, then it must be flagged as periodic. In addition, 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 method for each segment.
