Volume calculation is accessible by two different ways:
Right-click in Volume tab on the Workspace window and select "Calculate Volume"
Select Volume in the Tools tab on the top Ribbon
On the Calculate Volume display select design and existing surface by clicking Choose.
For each one of the surfaces a new display will open, and from there select the correct surface.
MAGNET Collage accepts as surface for volume calculation:
- Point cloud
Volume settings will be displayed additionaly on the Calculate Volumes dialog. The required parameters will depend on the type of selected surface.
- Standard: Cells are divided into four from the size select in Ground sample distance . Additionaly the volume of only the split cells which share a vertex included within the calculation range out of the four vertexes of the original cell is calculated.
- Custom: Choose the minimum number of vertexes of a cell needed to calculate volume. Only the cell whose vertexes are included within a calculation area exceeding the minimum number of vertexes is calculated.
Required height corner count : Set the minimum number of vertexes of a cell included within the area of a design surface and an existing surface to calculate volume.
Ground Sample Distance:The cloud can be performed the topographic resampling. It makes a topographic surface grid with the specified ground sample distance, chooses a point by the specified surface policy and removes the other points in the grid.
Origin Point Coordinate: Select an origin of the grid.
Surface Policy : The cloud can be performed the topographic resampling. It makes a topographic surface grid with the specified ground sample distance, chooses a point by the specified surface policy and removes the other points in the grid.
Bounded : Calculate with the present boundary of a plane.
Unbounded : Calculate considering the boundary of a plane as infinity.
Right-click a volume item on Workspace Window, then click "Volume Report" or click "Volume Report" in the "Edit" tab on the ribbon menu.
Volume report (TXT file format) will be displayed on an external text editor.
- When calculation method is standard, the half value of the ground sample distance set on Calculate volumes dialog will be written.
