To show the cut/fill to a DTM during stakeout

When staking out a point, line, arc, polyline, or alignment it can be useful to display the cut/fill to a digital terrain model (DTM), where the horizontal navigation is relative to the item you are staking but the displayed cut/fill delta value is from your current position to the DTM.

1. Tap and select Stakeout / [feature type].

2. Tap the Options softkey.

3. In the Deltas group box, tap Edit and, if required, select the DTM elevation delta. Tap Accept.

4. In the DTM group box, select the DTM.

5. If required, in the Offset to DTM field, specify an offset to the DTM. Tap and select whether the offset is to be applied vertical or perpendicular to the DTM. The V.Dist DTM value is to the offset position.

6. Stake out the road as usual.

   When a horizontal construction offset is applied, the cut/fill value reported is to the DTM at the position selected for stakeout and not to the DTM at your current position.

   When viewing the cross section, the DTM is displayed at your current position as a green line. A circle on the DTM indicates your position projected vertically to the surface.
