Grouping the drilling points
If you need to modify several drilling points simultaneously, you can group them together provided they are on the same side
of the shape (nasal side / temporal side).
By default, the symbol is displayed: each drilling point can be modified individually.
Press .
> is displayed. All future modifications will be applied to all drilling points in the same way:
only the reference drilling point is modifiable,
the coordinates of the other drilling points are greyed out.
To un-group the drilling points, press again.
Reference drilling point
The first drilling point you create on a shape automatically becomes the 'reference drilling point' in relation to which the others are
positioned:
Each side (nasal and temporal) has its reference drilling point, identified by its dark blue colour .
It is identified by the symbol # on the left of its coordinates.
The drilling coordinates have been modified.>
