00:03
Autodesk Vehicle Tracking is a suite of transportation-related programs
00:08
that includes vehicle swept path prediction for steered vehicles, light rail vehicles and aircraft, parking layout design, and roundabout design.
00:19
In this example, you use swept paths to analyze and predict the movement of a vehicle in a roundabout corridor in Civil 3D.
00:30
Swept path analysis is the evaluation and calculation of the space required for a vehicle to make turning maneuvers.
00:38
Open a file with a roundabout corridor in Civil 3D.
00:43
To make the roundabout corridor easier to work with, select it and hide the corridor, so that only the CAD linework is visible.
00:53
From the Vehicle Tracking tab, in the Swept Paths panel, select AutoDrive Arc.
01:00
In the Vehicle Library Explorer, select a vehicle.
01:05
For this example, navigate to World Wide Real Vehicles > Buses & Coaches > Blue Bird School Buses,
01:14
and select Blue Bird All American Rear Engine 189 School Bus.
01:20
Click Proceed.
01:22
A prompt appears asking if you would like to make this the default vehicle.
01:27
Click No.
01:29
Move your cursor or crosshair towards the right lane on Arm 3 (South).
01:35
Notice that the vehicle tracks along the visible lines.
01:39
Click a point along Arm 3, and move your cursor in the direction of vehicle movement.
01:45
The AutoDrive dialog can also be used to select and add Minimum radius, Clearance offset,
01:53
and Turn onto bearing settings, if needed.
01:57
Click along to sketch the perceived motion of the vehicle.
02:01
A green envelope is generated.
02:03
Press ESC when the path is completed.
02:06
Click the blue grips along the swept path to add points, if needed.
02:12
Select the swept path, and from the ribbon, in the Review panel, click Animate.
02:18
From the Vehicle Tracking Animation bar, click Play to view the vehicle swept path in 2D.
02:25
To view the swept path in 3D, select 3D Animate, and then click Play again.
02:33
Select Camera to take a snapshot or Fly-By Camera to create a camera flythrough.
02:40
Click Record to save the desired animation to .avi video format.
