| Name | Description |
| Add | Method that creates a control point spline based on the set of input points that define the vertices of the control polygon. A closed spline is created when the start and end points have the same coordinate. |
| Name | Description |

| Count | Gets the number of items in this collection. |
| Item | Method that returns the specified SketchControlPointSpline3D object from the collection. |
| Type | Read-only property returning kSketchControlPointSplinesObject indicating the type of object. |
| Name | Description |
| Control point, equation, and intersection curve creation. | This sample demonstrates several new curve creation techniques introduced in Inventor 2014. It creates a new part and then create a 2d control point spline and a 2d equation curve. Surfaces are created from these two curves by extruding them. A 3d intersection curve is created between the extrusions. A 3d control point spline and 3d equation curve are also created. |
