# To show the cut/fill to a surface during stakeout

When staking out a point, line, arc, polyline, or alignment it can be useful to display the cut/fill to a surface, 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 surface.

1. Transfer a surface file to the appropriate project folder on the controller.
2. Make sure the file containing the surface is visible and selectable in the map.

   If it is available, your current position, the surface elevation, and the distance above (cut) or below (fill) the surface appear in the map screen.

3. Tap and select Stakeout / [feature type].
4. Enable the Cut/Fill to surface switch.

   1. In the Surface field, select the surface file from the current project folder. Alternatively, in the map select surfaces from BIM files. The Surface field indicates the number of surfaces you have selected in the map.

      If you cannot select surfaces in the map, make sure the BIM file is set to selectable in the Layer manager. If the Selection mode button on the BIM toolbar is button is yellow , tap it and select one of the Surface selection modes. To select a different surface from the map, double-tap in the map to clear the current selection and then select the new surface.

   2. If required, in the Offset to surface field, specify an offset to the surface. Tap to select whether the offset is to be applied vertical or perpendicular to the surface.

   3. To show the distance to the surface in the stakeout navigation screen, tap Options. In the Deltas group box, tap Edit and select the V. Dist surface or the Perp. Dist to surface delta. Tap Accept.

5. Stake out the selected item as usual.

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