Add Gearing FB

1.Click Geometry toolbar > Add Spline

OR

1.Click Add menu > Geometry sub-menu> > Add Spline

Then

2.Click in the graphic-area to add the first Nodes for the Spline

3.Continue to click at different places* to add more nodes

To end Add Spline:

4.Click the first node again to add a Closed Spline
OR
Click the last node again to add an Open Spline.


* Click a Point (Point, start-Point, end-Point, center-Point) of a different sketch-element to merge it with a node.

The Spline curve is now in the graphic-area.

Edit a Node's Position

Part-Editor: Add dimensions or Constraints

OR

Part-Editor: Drag the node

OR

Mechanism-Editor or Part-Editor : Use the Point Properties dialog


Edit the Spline's Angle at a Node

1.Mechanism-Editor or Part-Editor : Click the Spline to show the Spline-Handles

2.Mechanism-Editor or Part-Editor : Drag the arrowhead of a spline-handle around its Node

3.Mechanism-Editor or Part-Editor : Click the Spline again to hide the Spline-Handles


Edit the Spline's Curvature at a Node

1.Mechanism-Editor or Part-Editor : Click the Spline to show the Spline-Handles

2.Mechanism-Editor or Part-Editor : Drag the arrowhead of a spline-handle further from or nearer to a node

3.Mechanism-Editor or Part-Editor : Click the Spline again to hide the Spline-Handles

Spline-Handles of an Open-Spline and a Closed-Spline

Spline-Handles of an Open-Spline and a Closed-Spline

Notes:

The direction of the spline at a Node is normal to its spline-handles

The Radius-of Curvature of the spline at a Node is proportional to the length of its spline-handle

The Radius-of-Curvature of the spline at a Node is symmetrical to the two sides of its spline-handle.

You can add Constraints to Nodes, but not the Spline's curve.
