Creating a Walkthrough
In addition to still perspective views, you have the ability to create animation paths called
walkthroughs. Creating a walkthrough is much like creating a series of connected camera
views. Like any other 3D view, a walkthrough can be generated using any of the visual styles
and settings we described previously in this chapter. In the following exercise, you will
continue to use the c11-Visualization-Start.rvt file.
1. From your plan view, start placing a series of cameras by setting the camera location and
then the camera direction.

Note that each time you pick a location, these cameras will become the key frames in
your animation. When you have placed the last camera, press the Esc key and your
finished path will appear (Figure 11.53).
