Working with corridors in Autodesk® Civil 3D® often requires precise tracking of where individual infrastructure elements begin and end along the alignment. Manually extracting this information can be time-consuming and error-prone—especially when dealing with multiple feature lines across both sides of a corridor.

This add-in streamlines the entire process.

The application enables users to quickly generate COGO points at the start and end of selected corridor feature lines, with fully customizable labels that display stationing relative to the corridor baseline. This provides immediate graphical insight into the extents of each infrastructure element directly within the drawing.

In addition to graphical labeling, the app generates comprehensive tabular reports that include:

• Start and end stationing of feature lines
• Individual feature line lengths
• Clear grouping by left and right side of the corridor

These tables can be created directly inside the model space for documentation and review, or exported externally (CSV format) for further analysis, quantity takeoffs, or reporting in tools like Excel.

Key Benefits

• Eliminate manual station tracking and labeling
• Improve accuracy and consistency in documentation
• Speed up quantity verification and design validation
• Provide both graphical and tabular insight into corridor elements

Core Features

• Automatic creation of COGO points at feature line start and end positions
• Custom labeling with stationing relative to baseline
• User-defined label text for start and end points
• Generation of tabular reports with stationing and lengths
• Model space table creation for in-drawing documentation
• Export of tabular data to CSV (Excel-compatible format)
• Intelligent grouping of feature lines by corridor side (left/right)

This tool is ideal for civil engineers and designers who need a fast, reliable way to document corridor feature line extents and generate structured reports for design review and construction documentation.

The application is actively being improved. Feedback, suggestions, and feature requests are welcome.
