### 10.7.4. Camberline/Thickness Definition Sub-feature

The CamThkDef sub-feature controls the shape of the blade profile on a given layer based on user defined curves for the angle and thickness distributions. Because the curves can use any number of defining points, you can choose which points to define through parameters; not all points need to be parameterized.

To parameterize a control point, select the CamThkDef sub-feature (under a Blade or Splitter feature), right-click in the angle/thickness graph and select Use as Input Parameter, then select the control point. It will appear in the details view for you to assign a parameter to the X and/or Y values, just as you would for any other DesignModeler feature.

Basic functional behavior:

- Details view for parameters for graph points are grouped as angle or thickness parameter points. These points are displayed only on the root node, not under the Blade or Splitter feature.

- BladeEditor highlights a point on the graph when that point's parameters are selected in the details view.

- Changes to a free graph point are updated in the details view.

- Selecting a check box to set a point's X or Y value as a parameter will constrain the point's movement in the graph view. The point will be displayed in gray if there is only one constraint, or black if both X and Y are constrained.

- If the check box is cleared, the parameter will be removed from the parameter set.

- Point highlighting on the graph is cleared if the active feature is changed.

- In the details view that shows the input points, you can right-click for a context menu that contains the Delete command, which deletes an input point. This menu item is available only if the check boxes for both the X and Y values are cleared.

- If a Beta Definition is specified, you can parameterize the theta reference value.

- If a point in a graph is used as an input parameter, and you right-click it and delete it using the context menu, the corresponding point parameters are removed from the details view.

Note: The technique for setting input parameters for control points in the Stacking view is the same as that for the control points in the Angle and Thickness views. The stacking view is described at Section Stacking View.
