Offset geometry from ellipse

Offset geometry from an ellipse, or trimmed ellipse. Use this technique to represent a uniform wall thickness.

1. On the ribbon Sketch tab Draw panel , click Ellipse , and create an ellipse.
2. On the ribbon, click Sketch tab Modify panel Offset .
   Note: The ellipse responds to cursor movements. Pause the cursor near the ellipse quadrants to display an axis. When the axis is visible, the offset produces an ellipse. If the axis is not visible, the offset produces an associative spline.
3. (Optional) Right-click, and clear check marks to remove the default settings that affect the results of an offset ellipse.

   • Loop Select Chooses closed loops.
   • Constrain Offset Constrains the distance between the offset geometry and the original ellipse to be equidistant.
4. Click the ellipse.
5. Move the cursor to place the offset geometry, and then click to create.
6. To quit, right-click, and then click Done.
7. If the new offset is an associative spline, use Dimension to specify an offset distance.
8. (Optional) To break the association between the ellipse and the offset spline, right-click, and click Convert to Spline. After you break the association, you can add dimensions and constraints separately.

   Right-click the spline, and then set options to adjust spline shape, if necessary.
