Creates a curve of the specified degree.

Note: This command uses output arguments. C# and some scripting languages (such as JScript, PerlScript and Python) don't support arguments passed by reference so you need to use the best workaround for your situation:

For scripting languages this command returns an ISIVTCollection which you can use to get the output arguments.

For C# you can use the XSIApplication.ExecuteCommand method to call this command. ExecuteCommand packs the output arguments into a C# System.Object containing an Array of the output arguments (see Calling Commands from C#).

CreateCurve( [Degree], CurveType, [Points], [Local], [Value] );

Parameter	Type	Description
Degree	Integer	Degree of curve Default Value: 3 Possible Values: Description: 3 Cubic NURBS Curve 1 Linear NURBS Curve
CurveType	Integer	Specifies whether the curve is interpolated Default Value: 1 Possible Values: Description: 1 Interpolated Curve 0 Non-Interpolated Curve
Points	String	Comma-separated list of points. At least one point is necessary. For example, "(0,1,0),(0,2,0),(3,3,0)".
Local	Boolean	True if points are in local coordinates, False if they are in global coordinates. Default Value: False
Value	X3DObject	Returns the curve

VBScript Example

' This example creates curves:

' 1) Cubic  non-interpolated curve

' 2) Cubic      interpolated curve

' 3) Linear non-interpolated curve

' NOTE: That a linear interpolated curve will give the same trace as linear non-interpolated curve.

' NOTE: Put no spaces in point list.
