Concentric

Force two circles to share the same center while retaining independent radii.

Purpose#

Force two circles to share the same center while retaining independent radii.

Where to find it#

While editing a sketch, open Constraints and choose Concentric.

Selection#

• Tap two circles.

Steps#

1. Select the reference circle and second circle.
2. Confirm their centers coincide.

Options#

Result#

A Concentric constraint is added only when both circles can share a center. An incompatible fixed relationship is rejected without changing the sketch.

Editing#

Dimension either radius independently, or use Manage Constraints in a relationship constraint panel and delete Concentric to separate centers. If a previously saved Concentric relationship becomes unsatisfied, Review Constraints highlights it for removal or repair.
