== Examining the Geometry of the Parametric Curve ==
The wizard used [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]]'s '''Curve Generator''' to create a parametric curve to model the solenoid object. In this case, your solenoid is indeed a helix curve. However, the wizard's definition gives a more generalized helical coil object with '''Super-Quadratic''' cross section. Right-click on the name of your solenoid in the navigation tree and select '''Properties...''' from the contextual menu. This opens up the "Curve Generator" dialog as shown in the figure below:

The definition of the three coordinate functions X(t), y(t) and z(t) also involves variables like "major_rad", "minor_rad", "height", etc. which you saw earlier in the variables dialog. To preserve the parameterization of your solenoid object, you should change its properties from the variables dialog rather than directly from its property dialog.
{{Note|[[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]]'s curve generator always creates polyline objects. Unlike ordinary polylines that are characterized by their node sets, the ones created by the curve generator are characterized by mathematical expressions or Python functions.}}
