The Horizontal Analysis command calculates horizontally swept path analysis.
First, draw the polygon line representing a vehicle movement axis. You can use the AutoCAD PLINE command or the Civil 3D alignment. Then invoke the Horizontal Analysis command to open the ˝New swept path analysis˝ dialog box, where you select the type of vehicle you want to use in the analyses.
To create the vehicle analysis press OK and select a polyline defining a vehicle route in the drawing.
