3.7 How to calculate volumes on Get3D Cloud
1. Open the 3D model.
2. In 3D view, select the Volume tool and draw a polygon.
3. Left-click on the model to draw the vertices of the polygon and left-click twice to draw the last vertex.
4. When you are finished drawing, under Volume Volume Calculation in the right-hand Detail Information panel, select Datum Plane Mode:
Average: The base plane is parallel to the XY plane and the height is the average height of all vertices.
Custom : The base plane is parallel to the XY plane and the height is a custom height.
Centre Point Plane: It connects the highest and lowest points and the base surface is parallel to the XY plane, the height is at the highest height of all vertices and the low is at the lowest height of all vertices.
Fit Plane: Fits a plane to the vertices, so that all vertices are at the minimum distance from the base surface. Recommended option when the entire boundary of the stockpile is visible and the base surface is a hard surface, a slope, or flat with the same altitude.
Triangulated: It connects all the vertices and triangulates the volume above and below the base surface. Recommended option when the entire boundary of the stockpile is visible and the surface is relatively flat.
Highest : the base surface is parallel to the XY plane and the height is at the highest height of all vertices. Recommended option when the required calculation is the filling volume of a sandpit, pool, pond, etc.
Lowest : the base surface is parallel to the XY plane and the height is at the lowest height of all vertices. Recommended option when part of the boundary is not visible.
5. After determining the datum plane, click [Calculate volume], the calculation results will be generated.
Fill volume (m³): Volume that is below the volume base. The volume is measured between the volume base and the surface defined by the DSM.
Cut volume (m³): Volume that is above the volume base. The volume is measured between the volume base and the surface defined by the DSM.
Volume Difference (m³): Volume Difference = Cut volume + Filled Volume.
