Progressive Base Plane Volumes

(This functionality is available with the Volumes module)

Computes the progressive volumes between nominated elevation ranges at defined elevation intervals.

Progressive Base Plane Volumes dialog box

Item	Used to
Block is active:	Indicate whether there is a block currently active. This message will read "Block is NOT active" if a block is not active. If there is an active block, then the volume computed will be of only that part of the model with triangles that are wholly defined by the block. That is, if there is an active block, the boundary of the volume calculation is defined by the edges of the displayed triangles. Ensure that triangle display is active in the Terrain Modelling/Display/Model command, and that the block check box is active in the Display/Features command, as this will display only those triangles which will be used in the volume calculation. Refer to the Block command for information on creating and using blocks.
Model name:	Displays the name of the currently displayed model from which the volumes will be computed. Any previously created model may be displayed using the Display/Features command. The description of the model is displayed beside the model number.
Surface Definitions
Base Elevation:	Key in the base elevation that you want the volume computed from. The units of the datum elevations will be as set in the Utilities/Configure/Units command.
Top Elevation:	Key in the top elevation that you want the volume computed to.
Elevation Interval:	Key in the elevation interval that you want the volume computed for.
From Base to Top:	Select this option if you want the progressive volumes computed from the base elevation up to the top elevation.
From Top to Base:	Select this option if you want the progressive volumes computed from the top elevation down to the base elevation.
Base:	Press this button to find the lowest elevation within the selected area and place the value in the Base Elevation edit field.
Top:	Press this button to find the highest elevation within the selected area and place the value in the Top Elevation edit field.
Computation type
Relative Interval:	Select this check box if you want the volumes to be progressively computed at selected intervals relative to the base or top elevation. For example, if the base elevation is 10.8, the interval selected is 1.00, and this is checked, volumes will be computed at 10.80, 11.80, 12.80 etc. Do not select this check box if you want the volumes to be progressively computed at absolute intervals from the base or top elevation. For example, if the base elevation is 10.8, the interval selected is 1.00, and this is not checked, volumes will be computed at 10.80, 11.00, 12.00 etc.
Cumulative:	Select this option to compute the total volume at each elevation interval.
Incremental:	Select this option to compute the volume between successive elevation intervals.
Header:	Select this check box if you want a header to go out with the results and for the results to be formatted into columns. Do not select this option if you intend reading the file into another application. The results will be space delimited.
Compute Cut:	Select this option to compute cut volumes.
Compute Fill:	Select this option to compute fill volumes.
Compute:	Computes the volumes at each defined interval and displays the result in a report. This report can be saved for future use.
Cancel:	Close the dialog box.
