| 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. |
