In order to view a road design in drive-through mode, a composite surface model must first be created. Before proceeding with the steps below, follow the process in Exporting Designed Surfaces.

Creating a Terrain Drive-Through

To drive through the terrain: select the feature you want to drive along in the Plan window.

1. File | Open , select your composite surface model (.terx file).

2. In the plan window, select the the feature you would like to drive-through (ie. road centerline).

3. Activate the 3D window (if not shown, select View | New Window |3D)

4. 3D | Drive Through or <right-click> in the 3D window and select from the context menu to open the dialogue box below.

Figure: Drive Through Control Dialogue Box

The playback speed, start station and direction can be adjusted from here.

5. Press Options to bring up the Drive Through Options dialogue box as shown in Figure below.

Figure: Drive Through Options Dialogue Box

The contents for these options are:

  • Frame Sample Spacing - The interval at which the drive through will be sampled in the 3D view.
  • View Position – Height Above Path: The height above the driving path where the perspective will be generated.
  • Target - An object can be modelled in the drive through (i.e., a street sign or obstruction) by means of a position along path, height above, and the height and width of the object. Keep in mind that this object moves dynamically with the view and isn’t set in a permanent location.

6. We recommend, change the Frame Sample Spacing to 10ft. Press OK to close the Options Dialogue.

7. Press Play to begin the drive through, a sample of which can be seen below in Figure.

8. File | New. Do not save changes.
