Reference Surface

To enable or disable the use of reference surface for current topo survey or current stakeout task and to specify a surface as the reference.

When the reference surface is enabled for stakeout, the software automatically changes the elevation of the design point. The new elevation value is the elevation of the intersection point of the reference surface and perpendicular from the design point to the reference surface.

During stakeout, the Design Elevation and Cut/Fill values will be calculated from the specified surface.

During topo survey Cut/Fill value will be calculated from the specified surface. The Cut/Fill bar for reference surface can be enabled on the map views in the General tab of the Map properties dialog.

Note: To have these values displayed in customized data fields during stakeout or survey, select them in the Select Stakeout Value or Select Value to Display dialog, respectively.
