Toolbar:

Left-side of the graphics-area

Menu:

Add menu > Geometry sub-menu> > Add Spline

What to do:

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

2.Click Add Spline in the Geometry toolbar - 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.

The Spline sketch-element is now in the graphic-area.
An open and closed Spline. Spline-handles at the nodes.

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

Notes:

•A Spline may be open1s-red or closed2s.

To show the spline-handles3s, click the Spline.

•The direction of the spline is normal to the spline-handle3s
•The curvature of the spline is proportional to the 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.

To edit its geometric properties:

Edit the Node's Position

Use the Part-Editor:

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

Use the Point Display and Properties dialog-box

1.Double-click a node in the Part-Editor or the Mechanism-Editor

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

1.Click the Spline to show the Spline-Handles
2.Drag the arrowhead of a spline-handle further from or nearer to a node
