Create a Reference Plane

Open the “Module 10.1 - Fill Volume - Excavation” file by selecting “File> Open” and navigating to where the file is saved.

• Select “Refine > Extract Surface”.
• Name the plane “Reference Plane”.
• Use the Fill option to select the top points, as shown below.
• Use a value of 1 inch for the tolerance.
• Select Apply.
  

Cut and Fill Volume Analysis

• Now, the analysis will be performed.
  • Select “Evaluate > Floor/Grade Analysis > Cut and Fill Volume Analysis”.
  • Select the Cloud.
  • Select the “Reference Plane”
  • Enter 0 for "Tolerance threshold"
    • The tolerance threshold represents a certain distance above or below the reference plane to ignore. For instance, entering 0.25 inch would represent a small area above or below the reference plane where the volume would not be calculated.
  • Specify a Resolution (zone size). Use 2 inches for this exercise.
    • The zone size is the sampling distance on a grid for the analysis.
  • Select Lowest Point for Height Evaluation.
  • Check “Display result as a mesh”.
    • This will show the resulting point cloud as a mesh.
  • Uncheck “Detect walls”.
  • Uncheck “Clean up debris”.
  • Select Apply.
