Analyzing the site model

The individual cut and fill calculations for a site model can be listed in a report for verification.

1. Select the site model to analyze. Only one site model can be analyzed at a time.

The Create Site Model Volume List dialog box opens. On the Columns tab, select the columns of site model data to include in the report.

Parameter	Description
Available Columns	Lists the columns that can be selected for inclusion in the report
Selected Columns	Lists the columns to be included in the report; to change the list order, use the cursor to drag and drop the items to move in the # column.
Add >	Adds one or more selected items from the available list to the end of the Selected Columns list
Add All >>	Adds all available columns to the end of the Selected Columns list
< Remove	Removes one or more selected items from the Selected Columns list
<< Remove All	Removes all column items from the Selected Columns list
Column Parameters
Triangle Index	Creates a numeric index for each triangle that makes up the site model Triangulated Irregular Network (TIN)
Existing Surface Area	Lists the surface area of each triangle in the existing site model
Proposed Surface Area	Lists the surface area of each triangle in the proposed site model
Projected Area	Lists the projected area of the common (existing and proposed) site model triangles
Existing Volume	Lists the volume of each triangle (extruded to the existing site model’s Minimum Elevation plus its Datum Elevation)
Proposed Volume	Lists the volume of each triangle (extruded to the proposed site model’s Minimum Elevation plus its Datum Elevation)
Cut Volume	Compares the existing and proposed volume for each triangle in the site model, and displays the extra volume present in the proposed model
Fill Volume	Compares the existing and proposed volume for each triangle in the site model, and displays the volume removed from the proposed model
Net Cut & Fill Volume	Lists the fill volume minus the cut volume for each triangle in the site model
Total Cut & Fill Volume	Lists the fill volume plus the cut volume for each triangle in the site model

3. On the Grade Limits Modifiers tab, select the grade limits site modifiers to include in the report calculations.

Parameter	Description
Available Grade Limits Modifiers	Lists the grade limit-type site modifiers in the drawing; grade limits modifiers are identified by an assigned number
Selected Grade Limits Modifiers	Lists the site modifiers to be included in the report calculations
Add >	Adds one or more selected items from the available list to the end of the Selected Grade Limits Modifiers list
Add All >>	Adds all available modifiers to the end of the Selected Grade Limits Modifiers list
< Remove	Removes one or more selected items from the Selected Grade Limits Modifiers list
<< Remove All	Removes all items from the Selected Grade Limits Modifiers list
Show Modifier	When a numbered grade limits modifier is highlighted, selects the associated site modifier in the drawing, and zooms in so the site modifier is easily identifiable
Modifier Parameters
Outside Grade Limits	Includes all areas of the site model surface without any modifiers
Grade Limits Modifier __	Each grade limits site modifier in the drawing is identified with a number. If you have provided a name for the site modifier on the Data tab of the Object Info palette, the name displays in parentheses

Parameter	Description
Show Data for Unmodified Site Model Surface	When selected, the report includes the entire surface of the site model. Deselect this option to exclude the unchanged surface between the existing and proposed site models from the report.
Create Text File	Creates a tab-delimited text file of the report, which can easily be imported into a spreadsheet program for further manipulation. Specify the name of the text file and the location to save it in.
Create Triangle Group	Creates a group containing subgroups of polygons and volumetric data text for each triangle that makes up the site model triangulated network. For complex site models, a significant amount of information is displayed; adjust text size of the entire selected group with the Text > Size command.
Create Worksheet	Adds a Volume List worksheet containing the volume data to the current file
