Control Polygons A control polygon is a sequence of control points (nodes) in space used to manipulate an object's shape. Dragging control points as opposed to spline points localizes the area of change, giving you more precise control over the spline’s shape. Contents Displaying Control Polygons by Default Displaying Control Polygons Using Control Polygons Spline Polygon PropertyManager You can control the shape of a 2D or a 3D spline by dragging or setting values for the control polygon nodes. Changing the locations of the control points (nodes), updates the values of the X and Y Coordinates (in 2D splines), and X, Y and Z Coordinates (in 3D splines) in the PropertyManager.
