How to Use Custom Surface Comparison

Measuring material on uneven or stepped ground, stored in bins, stacked against benches, or in overlapping piles can require more customization than the interpolated base used by the Smart Volume

Custom Surface Comparison allows for precise adjustment of individual vertex points that make up the outline of a volume measurement. Adjusting the position and elevation of the vertices allows the measurement base to reflect the material in the stockpile accurately.

2. Choose a Calculate Volume template, such as Stockpile.


3. Outline your stockpile or use the Magic Polygon tool to draw a polygon boundary automatically.

4. Select the surface comparison you want to make. In this case, choose Smart Volume for the From or To Surface in the dropdown menus. 

Change measurement units

Select the most appropriate measurement unit for distance, area, volume, and density from the dropdown menu. This makes it easy to move between imperial and metric units as needed and create reports in your preferred units.

How to edit the custom base

Move a single point


Click on the point you want to edit. You can drag the point to a new location, or edit the northing, easting, elevation, and offset of the point.



Move multiple points

Hold the shift key and click and drag a box around the points you want to edit.


Shift the entire polygon

You can also move the entire polygon by clicking the icon in the center of the polygon and dragging it to the new location.


6. Click SAVE to recalculate the volume.
