Extend a surface body

Use the Extend command to make a surface larger in Fusion.

1. Click Design > Surface > Modify > Extend .

   The Extend dialog displays.

2. Select the edges on the surface body to extend.

3. On the Feature tab in the Extend dialog, select the Extend Type, and adjust its associated settings:

   • Natural: Extends existing face.
     • Select an Edge Alignment setting:
       • Free Edges: Applies G0 point continuity.
       • Align Edges: Applies G1 tangent continuity.
   • Perpendicular: Creates new faces perpendicular to the existing face.
   • Tangent: Creates new flat faces tangent to the existing face.

4. Drag the Distance manipulator handle to extend the surface, or specify an exact value in the dialog.

5. Optional: On the Analysis tab, select an Analysis Type to analyze the previewed result in context:

   • None: Displays no analysis.
   • Zebra: Displays alternating black and white stripes on a body to help you analyze surface curvature.
   • Curvature Map: Displays a color gradient on a body to help you analyze areas of high and low surface curvature.
   • Isocurve Analysis: Applies UV mapping and curvature combs to help you analyze the quality of the surface curvature.

6. Click OK to finish.

The extended surface body displays in the canvas.

Tips

• You can extend edges through another shape and then remove the excess with the Trim command.
• If you uncheck Enable Chaining, you can select a single edge without selecting its adjacent edges.
