DTM Stakeout

a. All the polylines in the

current job are displayed.

Select the appropriate

polyline and tap to return

to the Setup DTM 3D screen.

8. If a boundary is used, you must also

select one of the two radio buttons in the

Setup DTM 3D

screen:

Exclude points…

: will move any

objects that occur outside the selected

boundary to the Auxiliary layer.

Discard the boundary…

: will initially

move any points that exist outside the

boundary to the Auxiliary layer. If a point is

later stored outside the boundary, the

selected boundary is automatically

unselected.

Select any Break-lines (optional)

Break-lines are used to define any linear surface that has an abrupt

elevation change, such as a trench, or the face of a cliff. Break-lines

are necessary for an accurate TIN to be created for these surfaces.

Polylines or alignments are used to define any number of break-lines,

but if a boundary is used, the entire break-line must fall inside the

boundary – if any part of a break-line touches the boundary, the

break-line is invalid.
