Corner tangency controls

The Corner Tangency Options dialog is launched by double-clicking the Left Mouse button on the control, or clicking the Right Mouse button on it, and selecting OPTIONS… from the popup menu.

Corner tangency present a single option. Checking Make control point planar with corner tangents has the following effect: the wedge control point (that affects the tangency across two edges of the patch) is moved onto the plane formed by the two control net legs that are joined to the corner control point. This is illustrated in Figure 3:116 below. This occurs when Apply is clicked.
