Sectional Volumes | Introduction
- Live Subgrade View: When you select a chainage on a string, the tool presents a live view of the subgrade template applied to that specific string. Additionally, polygons representing the different areas of cut and fill are displayed.
- Visualisation Tools: The settings tab provides options to toggle the display of subgrade polygons and separate polygons, allowing for clearer visualisation of cut and fill areas.
- Automatic Intersection Trimming: The software automatically trims out the intersection on any road string. This means that the volume calculations are not affected by the subgrade for the kerb/curb return replacing the road subgrade in the intersection area.
- Accurate Subgrade Calculation: The tool only calculates the road subgrade where the road actually begins, taking into account the varying positions of kerb/curb tangent points. This ensures accurate volume calculations.
- Stripping Value Application: If a stripping value is applied through the Design Data Form, it is automatically factored into the calculations for all sections.
Sectional Volumes | Multi Section Viewer
A new multisection viewer provides a comprehensive view of all cross-sections for a selected string in a single environment. This viewer offers:
- Easy navigation functionality.
- Export capability as a DWG file.
- Options to customise spacing and visuals for plotting.
Sectional Volumes | Calculation Method
The sectional volumes tool uses the average end area method to determine the volume of cut or fill between two cross-sections.
The method calculates the area of fill or cut at each cross-section. Then, the average area of the two cross-sections is calculated. This average is then multiplied by the distance between the two cross-sections, producing the volume of cut or fill. This process is repeated for each subsequent cross-section along the alignment, with the cumulative volume of cut or fill being tracked throughout.
To coincide with the Autodesk 2024 release, Civil site design v24 will be released featuring a number of new and improved features, here is an overview of what’s in this release. A Civil Site Design toolspace has been developed from which users can design and edit & manage the roads and modelling content within their […]
