Adding a Swept Edge Form to Your Design
- Sketch a profile at an endpoint of the edge.
- Enter the Pull tool.
- Click the Sweep tool guide.
- Click the Full Pull tool guide.
 
            The vertical line will be swept along the arc to create the form.
 
            Notice that the sweep profile is a single line and an Inside Radius arc is automatically added to the profile, at the attachment point, to produce a bend. If you draw a tangent arc along with a line, then that arc determines the bend radius and overrides any inside radius automation that is done in the case of only a straight line.
 
            Swept Edge Forms can be unfolded.
