Motion 3D Viewer
This command creates moving vehicles for the Surface 3D FlyOver
viewer. The vehicle paths are set by assigning a vehicle icon and
speed to polylines. This command docks a dialog on the left of the
drawing.
Use the Select Path Polyline function
to tag a polyline as a path polyline. After selecting the polyline
from the drawing, the dialog shows a spreadsheet of the transition
points along the polyline. The speed is set at each point. When
running the animation, the vehicle speed will be interpolated
between these transition points as the vehicle moves along the
polyline. At a minimum, there are two transition points for the
start and end of the polyline.
The direction of the polyline in the drawing controls the direction
of the movement in the viewer. When the polyline is 3D, the viewer
will use the polyline elevations. When the polyline is 2D, the
viewer will drape the polyline on the surface to set the
elevations.
When the path polyline is selected, the Path Type chooses whether
to use the polyline for the camera view position in the viewer or
for drawing a vehicle icon.
Use the Set button to select a Symbol for the vehicle icon. The
list of available symbols comes from the 3D Model Library
command.
Use the Add Transition function to add a speed transition point on
the polyline path. The Add Impact creates a special transition
point that represents where a vehicle had a collision. For this
impact transition point, there is both a speed in and out to
represent the sudden change in speed.
The Save Log File option creates a log playback file (.pos) which
can be used by Surface 3D FlyOver.
The Clear Path Data function untags the path data from the selected
polylines.
The Settings function show a dialog with settings for the temporary
symbols that are shown in the drawing to indicate the transition
points along the polyline.

When the path polylines are all set, use the Launch 3D Viewer
command to display the scene with the vehicle animation. The view
controls are the same as the Surface 3D FlyOver command. Pick the
Run button to put the vehicles in motion.
