Make sure that Stake tunnel and Stake: Stake face is selected.
In Tunnel Settings, Tunnel design page, set Drilling rig orienta-
tion: Parallel to alignment. Refer to "Road Settings,Tunnel design
page".
In the Define panel check Check Jumbo position and type in the
values. Refer to "Defining the Work".
If Drilling rig orientation: Parallel to alignment was selected in
Tunnel Settings, Tunnel design page and Check Jumbo position
was checked in the Define panel, then proceed to define the drill
entry position on the tunnel face by entering the respective centre-
line offset in Stake Face,
In Stake Face, General page, enter the approximate tunnel face
chainage. To position the laser pointer to the drill entry point press
FnPosition to find the point.
Position the drill bit to the laser point on the tunnel face.
Now the jumbo boom moves onto line between the laser point on
wall and the telescope so that the laser now points at the back of
the boom. Press Fn Tools. Select Check Jumbo position to get the
delta angles which are used by the drilling rig to move the boom par-
allel to the alignment.

Make sure that Stake tunnel and Stake: Stake face is selected.
In Tunnel Settings, Tunnel design page, set Drilling rig orienta-
tion: Drill Pattern. Refer to "Road Settings,Tunnel design page".
In the Define panel, check Drilling rig orientation and select the
app of the drill pattern. Refer to "Defining the Work".
If Apply drill pattern from: Defined Chainage was selected, then
proceed to define the drill entry position for the measured chainage
by entering the defined chainage centreline offsets in the Stake
Face, page and the drill angles according to the defined chainage.
In the Stake Face,
Stake chainage editable field. To position the laser pointer correctly
on the measured tunnel face press Fn Position.

The delta chainage value after using Fn Position is the
difference between the defined and measured chainage. It
is normal if the delta is large. The delta position and delta
height values after this step should equal zero.
