In a system and method for controlling a reflection line in a CAD system and for adjusting the shape of an object to correspond to a new reflection line, a user sets a reflection line as desired, and at least one constraint on the object. The system determines a shape of the object based on the new reflection line and the constraint. The shape of the object may be determined using energy minimization. Alternatively, the system and method may use vector springs to attract the reflection line to a free-form curve set by the user, and then determine the shape of the object based on the new reflection line and the constraint.
