below (the latter two can be found in the Surface Properties folder).įigure 8: Add/Remove Items to Status Window Change the Selected items list to include only Area, Vol. Attributes can be added if you press the button at the base of the Feature Properties panel and press the Add/Remove… button. Volumes can also be viewed in the status portion of the Feature Properties panel. To view the values again, create a status window by Terrain Modeling | Display Volumes button. Note the cut, fill quantities and surface properties are reported for the 2 polygons (lease-0 and lease-1). If you are working in imperial units (feet) the volumes will be reported in cubic yards.įigure 7: Volumes/Surf. Properties Reporting dialogue box will appear (figure below). Press OK to begin the volume computation. Check Volumes and surface properties by polygon and ensure all other selections are as indicated in the figure above.Terrain Modeling | Calculate Volumes button to open the Volume / Surface Properties Calculation dialogue box shown in below.įigure 6: Volume / Surface Properties Calculation.Note: When a feature has surface / volume boundary set volumes, surface area, slope and slope direction will be calculated and assigned to the feature as attributes. If not visible press the Zoom Out button on the tool bar.įigure 5: Original Topography with Boundary Polygons Two boundary polygons should now be visible in the Plan Window as in the figure below.
Softree Warning may appear, select do not display again.
#Surpac polygon method how to#
The following steps demonstrate how to include two polygonal boundaries and calculate the volume inside each one. The order of these surfaces is not important as you will see later.įigure 4: Volume / Surf. Surface A should be set to original ground.terx and surface B should be set to excavation.terx.

The files referenced in the article, as well as the full tutorial document, are available in our Tutorial Installer.Ĭut and fill quantities can be computed between any two triangulated surfaces or one surface and a TIN Boundary (another polygonal boundary can also be included to restrict the calculation to a specific area).
