Use the table and report creation commands to analyze sectional volumes.
You can create tables and reports for:
- Volumes along an alignment, comparing various design surfaces and existing ground surfaces.
- Volumes for shapes, which are closed cross-sectional areas created by a single subassembly. For example, a curb (a closed area within a concrete curb or curb and gutter).
- Volumes between various (designed/grading/existing) formations.
The results of a quantity takeoff calculation are displayed using one of the following three methods:
- Total Volume Table
- Material Volume Table
- Quantities Report
A Total Volume Table contains cut, fill, and cumulative volume information (for example, an earthworks or cut/fill report).
A Material Volume Table contains cut, fill, and cumulative volume information for a specific material in the material list (for example, the cumulative volume of a structure element).
A Quantities Report is an XML format file that contains the criteria definition (comparable surfaces), material types (such as cut type), shrink and swell factors, as well as refill factors. The specific format is determined by the style sheet you select.
Before you create a quantity takeoff report or table, materials must be defined in the Sample Line Group properties or computed using the Compute Materials command.
You can display quantity takeoff information using standard AutoCAD Civil 3D table formats or view and export it in an XML format file.
Three style sheets installed with AutoCAD Civil 3D are used to create external quantity takeoff reports:
- Earthworks.xsl. Reports station-by-station values in a tabular format for cut and fill volumes, incremental volumes, and cumulative net volume.
- Select Material.xsl. Reports station-by-station values for the selected materials. At each station, all selected materials defined in this criteria and cumulative volumes are reported.
- Mass Haul - Multiple Materials.xsl. If you have defined many material types to remove (for example, for embankment creation for road widening along the corridor), you can use this style sheet to aggregate the material types and produce material-by-material reports at each station as well as aggregate volume reports for mass hauls.

To create a total volume table
- Click Analyze tab
Volumes And Materials panelTotal Volume Table
At the Command prompt, enter AddTotalVolumeTable. - In the Create Total Volume Table dialog box, select a table style and layer.
- Click the Select Alignment field. Select an alignment from the list or click
to select an alignment in the drawing. - Click the Select Sample Line Group field. Select a sample line group from the list.
- Click the Select Material List field. Select a material list from the list.
- Optionally, select Split Table, and then specify the maximum and minimum number of rows in a table, the distance to offset tables from each other, and the method for arranging multiple tables.
- Under Behavior, specify whether the table is static or dynamic.
- Click OK.
The upper-left corner of the new table is attached to your cursor.
- Click in the drawing to set the location of the table.
