Create and adjust control vertex spline

Show Me how to create and use control vertex splines

First select a part face or work plane to use as the sketch plane . In a new file, select the sketch plane, and start to sketch.

1. On the ribbon, click Sketch tab Draw panel Control Vertex Spline .
2. In the graphics window, click to set the first point, or select an existing point.
3. Continue clicking to place more vertices.
4. Click OK to create the spline and exit the command. Click Apply to create the spline and remain in the spline command.

Note: The spline is tangent to the control frame at the start point and end point.

Adjust control vertex spline

• To delete the spline without deleting the spline fit points, convert the points to center points.
• To edit the position of spline control vertices, click and drag a vertex.
  
• To edit the position of the spline control frame, click and drag a line.
  
• Reposition the spline by adding dimensions and constraints to the control frame, or between the control frame and other geometry.
• Use the context menu options to:
  • Add a vertex.
  • Close the spline.
  • Convert to an interpolation spline.
  • Change the control frame polygon visibility.
