Parameters

PointData

Set of X,Y,Z point coordinates to use in creating the spline (see Remarks)

Return Value

This method creates a spline in the active 2D sketch. If a sketch is not active, then a new sketch is created. Use IModelDoc2::GetActiveSketch2 or IModelDoc2::IGetActiveSketch2 to check if the sketch active.

The PointData array is a set of, at least, two X, Y, Z values. The X value for the start point of the spline is PointData[0], the Y value for the start point is PointData[1], and the Z value for the start point is PointData[2]. The X value for the next point is PointData[3], and so on. For the COM interface, the total number of points in the array must be passed in. For the OLE interface, the total number of points are determined automatically, by taking the UBound of the PointData VARIANT and dividing by 3, so be careful to dimension that array correctly.

For COM applications, you can use the object pointer returned from this method to call any APIs on the ISketchSegment interface. You can obtain the underlying ISketchSpline object by using QueryInterface on the returned ISketchSegment object.

OLE applications can define a new ISketchSegment or ISketchSpline object using the returned Dispatch pointer. Visual Basic applications interpret the pointer for you automatically, so you can use the returned object to call SketchSegment or ISketchEllipse APIs.

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) was in effect), and you must redraw your document window to see the entities that you added (as if IModelDoc2::SetDisplayWhenAdded(false) was in effect).

In 2D sketches, SolidWorks ignores the Z value in PointData.
