2. Customized bevels
◦ Front surface tracking: the crest of the bevel is positioned at a constant distance from the
front surface.
◦ Rear surface tracking: the crest of the bevel is positioned at a constant distance from the
rear surface.
◦ Distributed bevel: the position of the crest of the bevel is proportional to the thickness of
the lens, with respect to the front surface.
◦ Base monitoring of the lens: the camber of bevel is parameterized.
3. Lens thickness
◦ Maximum lens thickness - represented by the white square along the shape.
◦ Minimum lens thickness - represented by the red square along the shape.
4. Cursor movement
The cursor is represented by the green square along the shape. To move it, select it directly or use the
and buttons.
5. Zoom window
Represents the bevel profile and indicates the distance between the bevel crest and the front and rear
surfaces of the lens at the cursor position.
When preparing the edging of the second lens, the values of the first lens are repeated in parentheses.
6. Bevel distribution value
Distribution value modifiable for:
◦ front/rear surface tracking
◦ a distributed bevel
◦ lens curve tracking
7. Modify the selected value
Reduce or increase the distribution value.
8. Bevel trajectory
Flat representation of the lens making it possible to assess the distances between the bevel crest and the
front & rear surfaces of the lens.
9. Trajectory modification
◦ General modification of the bevel curve
◦ Modification of the bevel curve at a particular point
◦ Displacement of the bevel curve
