Defining Coincident Geometric Constraints

Use the GcCoincident command to define a coincident geometric constraint to two points on entities or to constrain a point on an entity to an entity. It keeps two entities aligned with each other.

To define coincident points on entities:

1. Click Constraints > Geometric Constraints > Coincident (or type GcCoincident).
2. Specify the first constraint point on an entity (Line, linear PolyLine segment, Circle, Arc, PolyLine arc, Ellipse, or Spline).
3. Specify the second constraint point on another entity.
4. The entity you specified for the second constraint point is modified so that it is coincident to the entity you specified for the first constraint point.
5. A blue square marks the coincident constraint points. Move the pointer over the square to display the constraints bar for coincident points, then right-click the constraints bar to edit the constraint.

To define coincident points by specifying an entity, then a constraint point:

1. Click Constraints > Geometric Constraints > Coincident (or type GcCoincident).
2. Specify the Entity option.
3. Specify an entity (Line, linear PolyLine segment, Circle, Arc, PolyLine arc, Ellipse, or Spline).
4. Specify a constraint point on another entity.
5. The entity you specified for the constraint point is coincident to the constraint point of the first entity.

To define coincident points by specifying a constraint point, then an entity:

1. Click Constraints > Geometric Constraints > Coincident (or type GcCoincident).
2. Specify the first constraint point on an entity (aLine, linear PolyLine segment, Circle, Arc, PolyLine arc, Ellipse, or Spline).
3. Specify the Entity option.
4. Specify an entity.
5. The entity you specified is coincident to the constraint point you specified initially.
