(b) Changing the position of the whole bevel parallel to itself
1) Align the cursor to
PNT
.
2) Press to simulate the bevel at the point
where the edge is thinnest (
J
).
3) Change the bevel tip point value to move
the bevel position toward the front or rear
surface of the lens.
: The bevel moves toward the front
surface.
: The bevel moves toward the rear
surface.

next to the value shows that the bevel
was moved toward the front surface.

next
to the value shows that the bevel was moved
toward the rear surface.
e.g. B CRV: A5.0
PNT :
→
0.6
This shows that the bevel was moved 0.6
mm toward the rear surface parallel to itself
while the bevel curve value was 5.0.
NOTE
• In order to avoid the bevel being off the lens edge, be sure to watch the simulation at
the thinnest position while changing the value.
Distinct from changing the bevel curve value, it is possible to specify a bevel tip
point which produces a single-sided bevel.
7. Check the bevel section.
1) Press to turn off the cursor.
2) Simulate the whole bevel to see if the
desired bevel is obtained. See Step 5 (p. 4-
20).
8. Repeat Steps 5 - 7 until the desired bevel is obtained.
