Many road design engineers draw sight lines manually in order to check potential visibility issues during the horizontal alignment design process. This app will automate the task of horizontal sight distance line generation. Note that in order to maximize compatibility, the command is designed to work with standard Autodesk® AutoCAD® polylines and not Autodesk® Civil 3D® objects.

Features:
•Adjustable distance and step parameters for sight lines generation.
•Built-in AASHTO Stopping Sight Distance (SSD) tables and equations for SSD values lookup and computation.
•Metric and Imperial units support.
•Table SSD values stored in a stand-alone text files – edit/add/remove table entries to customize as required.

Note: This app uses a custom installer (and not the standard App Store installer).
