This plugin is a game-changer for surveyors and engineers who need to create longitudinal profiles from field-surveyed 3D polylines. By simply selecting a 3D Polyline, the tool extracts the cumulative chainage and elevation of every vertex and saves them into a structured two-column text file. This output is perfectly formatted for the "Create Profile from File" feature in Autodesk Civil 3D, allowing you to instantly generate a precise longitudinal profile from your surveyed path without any manual data entry.
