MAGNET Tools: Compare surfaces

The Compare Surfaces icon of the Calculate group allows you to compute one of the following:

• difference between the volumes of two surfaces;
• difference between the volumes of a road and a surface;
• the volume of a surface/road relative to the horizontal plane of the defined level.

To compare surfaces:

1. In the GOGO group of the Report tab, click the Compare Surfaces icon.

   The Compare Surfaces panel is displayed.

2. From the Design drop-down list, select the first surface or road for comparison.
3. Do one of the following:
   • Select a surface for comparison.
     1. From the Existing drop-down list, select Surface.
     2. From the adjacent drop-down list, select the required surface.
   • Define a horizontal plane for comparison.
     1. From the Existing drop-down list, select Level.
     2. In the adjacent editbox, type the required level of the plane.
4. If needed, tick the Save as Surface checkbox, to save the result as an independent surface.
5. Click Calculate.
