Description
Shows or hides the display of the defininig Polygon of a B-spline (see this page for more info about B-splines).
A B-spline curve. The control polygon are the green straight lines connecting the control points.
Usage
- Select a B-spline and use the toolbar button
Show/Hide B-spline control polygon.
