Select the eye to be traced.
Enter the D-dimension, then press to confirm.
Tracing - tracing mode
In tracing - tracing mode, the result of the tracing is displayed in the work area of the tracing screen. For more information on
working modes, consult the section .Perform a trace > Tracing environment > Jobs and working modes (p.21)
Before Centering
Once tracing has been carried out, you can:
Input the curve angle and the frame base, for optimal centering precision
Modifying the lens shape For more information, consult the chapter .Modifying the lens shape (p.83)
Add drilling points on the shape. For more information, consult the chapter .Preparing a drilled job (p.91)
c. Inputting the curve and the frame base after monocular tracing
In a monocular tracing, the curve angle and frame base cannot be measured. For optimal centering precision, we recommend that
you enter those values after the optical or mechanical tracing of a pattern, recut lens or demo lens.
Prerequisite: before entering the curve angle and frame base, one of the following operations must be performed:
Optical tracing of a pattern, a demo lens or a recut lens (p.30)
Mechanical tracing of a pattern, demo lens or recut lens (p.32)
Input the curve angle and the frame base.
Press the button.
Select the curve angle value to modify it.
Place the frame on the screen:
The vertical blue line must be in the center of the frame
The plane which is tangent to the two lenses must coincide with the pink line at the bottom.
The buttons , , and are displayed.
