Defining Concentric Geometric Constraints

Use the GcConcentric command to make the center points of Arcs, Circles, Ellipses, or elliptical Arcs to coincide.

To define concentric Geometric Constraints:

  1. Click Constraints > Geometric Constraints > Concentric (or type GcConcentric).

  2. Specify the first entity (Circle, Arc, Ellipse, elliptical Arc, or PolyLine arc).

    The first entity is the one that maintains position.

  3. Specify the second entity (Circle, Arc, Ellipse, elliptical Arc, or PolyLine arc).

    The second entity moves so that its center point coincides with the center point of the first entity.

tip When you specify a PolyLine arc as the second entity, only the specified arc segment is made concentric to the first entity; the geometry of the PolyLine changes instead of moving entirely.
