Disclosed herein is a method of horizontally structured CADCAM modeling, comprising: establishing a coordinate system; adding a base feature; adding a form feature; where the form feature exhibits an associative relationship with the coordinate system. The chromic change agent alternatively may be associated with the ingestible, such as a packaging material for the ingestible. A relationship between the identifier and the femto cell is then communicated. The substrate has a thickness of material from a first substrate. The lateral sliding surface and the medial sliding surface of the intermediate element have different sagittal cross-sectional profiles. The rotational phase converter varies the rotational phase into the feasible phase with receiving the load torque from the shaft.
