IMITS OF HOLE POSITIONING
> Whatever the type of hole, it must be drilled in a specific zone which is defined following the diagrams below.
>
The following constraints must be observed:
→ The circle radius beyond which drilling is possible:
Note: When it is impossible to drill a hole (hole positioned in the end-pieces, notch passing
through the centre of the shape, this hole is shown in black in the screen. Some
holes displayed in blue in the screen may be impossible to drill after they have
been felt (holes too deep, unadapted angle, unadapted end-piece, etc.). In these
cases, these holes will be displayed in gray in the screen and only marked with
the mill bit end (with maximum inclination angle) during the drilling phase, once
the operator has accepted the marking.
→
The ring formed by the edge of the lens and the internal perimeter of the lens beyond which

holes cannot be drill ed. Do you want to continue? ». If you reply Yes: The entire
