ASYMMETRIC BINOCULAR TRACING
The two circles of frame are read as if they have different shapes; the perimeters and the shapes are
preserved.
BOXING DIMENSIONS
The boxing system is a standard method to indicate the dimensions of frame contours (or gauges). This
operation consists in fitting the frame into a rectangle whose dimensions are indicated.
• Boxing center: geometric center of the rectangle
• Boxing axis: horizontal axis of the frame passing through the boxing center
• A-dimension: length of the rectangle
• B-dimension: height of the rectangle
• D-dimension: nominal nose (DBL)
• E-dimension: greatest radius from the boxing center
• Boxing height: calculated from the tangent line at the bottom of the frame.
