Constrain arc or circle to be concentric

The concentric constraint causes two arcs, circles, or ellipses to have the same center point.

1. On the ribbon, click Sketch tab Constrain panel Concentric Constraint .
2. Click the first arc, circle, or ellipse.
3. Click a second curve to be concentric to the first.
4. Continue to place concentric constraints, or do one of the following to quit:
   • Right-click, and select Done.
   • Press Esc.
   • Select another command.

Note: The result of the concentric constraint application is the same as applying a coincident constraint to the center points.
