How you use Autodesk Vehicle Tracking depends to a large extent upon what you want to do with it.
The system is set up with default settings appropriate for a "typical" use. You will need to decide whether these are appropriate for your needs and change them if necessary.
The way a vehicle behaves is controlled partly by the vehicle parameters and partly by the environment in which it is driven. Vehicles once defined should normally be regarded as fixed. The environment settings however can and should be modified to suit your particular situation.
There are various drive modes available each of which can be used interchangeably. Each is appropriate for a particular use and you will need to decide which is best for your needs and indeed this may come down to a simple preference. All but one of the drive modes also have settings that control the way they work.
One of the most frequent causes of problems is that Vehicle Tracking is working in one set of units (say, meters) while your CAD system is working in another (say, millimeters); so before you start work make sure that you set the Vehicle Tracking scale to match your drawing (Refer to Drawing Settings: Scale).
Vehicle Tracking calculates swept paths to a high degree of accuracy based upon the stated algorithms. However, you may wish to allow for the driver error or real world imperfections by modelling a safety or clearance envelope (Refer to Drawing Settings: Reports: Offset Envelope 1).
