Using Control Polygons

To use a control polygon:

Sketch a spline.
Select a control point to activate it and display the Spline Polygon PropertyManager.
Drag the control polygon to adjust the shape of the spline.
You can also set values for the X Coordinate , the Y Coordinate , or the Z Coordinate (3D splines) in the Spline Polygon PropertyManager.
If necessary, click Relax Spline to smooth the shape after dragging.
Click .
