To Use the Drive Command

You can simulate driving through a 3D model using the Drive command.

When you start the command, you are prompted to select a path along which the Drive mode view will travel. The view changes to Drive mode view, and a contextual Drive tab is displayed in the ribbon.

A drive path can be a 3D polyline, alignment and profile, corridor feature line, grading feature line, or survey figure.

The Drive tab provides commands that enable you to play, pause, or reverse the display of driving through the model. You can change the speed of the drive simulation, as well as the eye location, visual style, and target object.

You can switch to another drive path while the drive command is active. If you have trouble selecting a drive path from within the drive view, you can open a separate viewport to select a path in plan view.

When you end Drive mode by clicking Close on the Drive tab, your view changes back to normal view.

1. Click Analyze tab Design panel Drive.
2. Select a linear object to use as a drive path, or press Enter to select a feature from the Select a Drive Path dialog box.

   The command line displays the supported object types.

3. If you selected an alignment or corridor, select an associated profile or select a feature line.

The Drive tab is displayed, and the view switches to the Drive mode view.

4. Click Navigate panelPlay/Pause to start the Drive command.
5. Click Play/Pause at any time to pause the motion. Other controls on the Drive tab let you navigate along the selected object.
