In this screen the dimensions of the Multi-face clock are input.
These are:
Central face width: This dimension refers to the width of the central face of the multi-face clock where the gnomon is placed. The program makes a simplifying assumption that the gnomon is vertically located in the center of this face (symmetrical case). If a nonsymmetrical sundial is desired, two designs are generated; the first with a central face twice the width of the larger lateral face and the second with a central face twice the width of the smaller lateral face. One lateral face from each design is chosen for the final nonsymmetrical design.
Lateral face width: This dimension refers to the width of the two lateral faces. The program assumes the same width for both faces. If this is not desired, the width of the larger face should be given and later clipped to the smaller size.
Height of the faces: This dimension refers to the height of all faces.
Face angles: This angular dimension refers to the angles between the lateral faces and the central face. These angles are measured from the plane of the central face. The lateral faces must rotate toward the observer and the angles are always input as positive values between 0º (flat) and 90º(boxed).
