SurvStns is an AutoCAD LISP script designed to automate the placement and annotation of survey stations along linear alignments. This utility performs a specific automation task by generating station markers and associated text labels along selected polylines or alignment paths within the AutoCAD environment. It streamlines the repetitive drafting process involved in civil engineering and survey documentation by calculating intervals and placing geometric symbols at user-defined chainage points. The script is lightweight and executes directly within the command line, providing a clean method for marking distances. It manages the insertion of point entities and corresponding dimension text, ensuring consistency across complex site layouts and infrastructure drawings where precise stationing is a critical requirement.

The download is a 31 KB file containing .LSP files.

To implement this tool, load the LSP file into your active AutoCAD session using the APPLOAD command. Once loaded, initiate the script via the defined command alias to select your alignment path. The plugin prompts for the desired interval distance and starting station value before automatically generating the markers and labels on the current layer. Ensure your text styles and point styles are configured appropriately in the drawing template prior to execution for optimal graphical output.

Professional civil engineers, surveyors, and infrastructure planners utilize this script for large-scale site development, road design, and utility network mapping. It is essential for projects requiring accurate chainage markers across extensive linear corridors, such as highway design, rail infrastructure, and site grading plans. By replacing manual drafting with automated stationing, users can significantly reduce errors in survey documentation. It integrates seamlessly into standard CAD workflows, supporting both preliminary design phases and final construction documentation for complex horizontal alignments within residential or industrial developments.
