Closed Spline (3D)

General

• Sketch a closed spline curve by clicking points. When you confirm the point selection as completed, the program also completes the curve between the first and last point you selected.
• Later, you can select the spline curve to display the control points (= grips) of the curve. You can snap to these points and drag them to new locations.
• If you do not select a work plane, the spline curve is drawn on the drawing plane, the plane that is currently facing you.

Draw a closed spline in a 3D sketch

1. Select the function 3D sketch | Lines | Closed Spline or
   • select the context-sensitive function Line > Closed Spline
2. If necessary, select the line properties, under 3D Sketch | Style
3. If necessary, select Workplane to sketch a spline curve on an auxiliary plane.
   • Add a Sketch Plane in the 3d Sketch.
   • Select a Sketch Plane as a Work Plane in a 3D Sketch.
4. Click the curve's control points.
   • Click at least 2 points for the curve.
5. Stop sketching this closed spline curve
   • Press the V key (V = Confirm) or
   • Press the middle mouse button.
6. Repeat steps 2 to 4 to continue sketching closed spline curves.
7. Stop drawing closed spline curves
   • Select another function or
   • Press the middle mouse button or
   • Press the Esc key or
   • Press the V key (V = Confirm).
