What to do :

Note: Add Spline is the only sketch-element (other than Add Point) in which you do NOT drag your mouse-pointer.

1.	Edit a Part

2.	Click Geometry toolbar >Add Spline in the - see image to the left

When Add Spline is the active command:

3.	Click in the graphic-area to add a Point, as the first 'node' of the Spline

- or -

Click an existing Point of a different sketch-element, as the first 'node' of the Spline

4.	Continue to click at different places in the graphic-area to add more nodes

To end Add Spline:

5.	Click the first node again to add a Closed Spline - or - Click the last node again to add an Open Spline.

An open and closed Spline.
Spline-handles at the nodes.

Notes:

•	A Spline may be open or closed.

To show the spline-handles, click the Spline.

•	The direction of the spline is normal to the spline-handle

•	The curvature of the spline is proportional to the length of the spline-handle

•	The curvature of the spline is symmetrical to the two sides of the spline-handle.

To hide the spline-handles (default), click the Spline again.

Edit the Node's Position

Use the Part-Editor:

1.	Add a dimension, to the node to edit its position.

Edit the Spline's Angle at the Node

1.	Click the Spline to show the Spline-Handles

2.	Drag the arrowhead of a spline-handle in a different direction

Edit the Spline's Curvature at the Node
