Use the material volumes functionality to extract and report sectional material volumes, based on sample line groups.
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).
You can display material volume information using standard AutoCAD Civil 3D table formats, or view and export the information in an XML format file.
Material volume reporting uses criteria settings that are portable and extensible. You can create criteria based either on existing data, including surfaces and sample line groups, or on standard surface names.
You prepare to generate material volume information by creating a list of materials and applying the predefined criteria to it, mapping existing surfaces or other objects to the names in the criteria. After the material list is generated, the settings and volume calculations are stored with the sample line group and can be used to generate tables and reports.
Topics in this section
- Sectional Volume Methods
When you compute the materials for a sample line group, you can use three different volume calculation methods: Average End Area, Prismoidal, or Composite.
- Sampling Sectional Volumes Across Multiple Baselines
You can include multiple baselines in a corridor volume calculation, but you should make sure that the assumptions for the volume calculation method are satisfied. That is, the distance (L) must be accurate for all baselines.
- Defining Materials
Create quantity takeoff criteria as the first step in analyzing sectional material volumes.
- Reviewing Sectional Volume Results Graphically
After you have created a material list for a sample line group, you can graphically review how the material volumes have been calculated.
- Creating Sectional Volume Tables and Reports
Use the table and report creation commands to analyze sectional volumes.
- Creating and Editing Quantity Takeoff Table Styles
Styles control the way quantity takeoff tables are displayed in a drawing.
