How to create a Walkthrough Path with Keyframes, and how to control the camera position in a Walkthrough in Revit:

1. In a plan view, go to the View tab, then to 3D View pulldown, and choose Walkthrough from the list.
2. Look to the Options Bar to set the Walkthrough to a Perspective, and to set the default camera height relative to a level.  Default setting is 5'-6" from Level 1.
3. Click in the plan view to place the first Key Frame, and continue to click in the plan to create additional Key Frames and the Path for the walkthrough.
4. Click the Finish Walkthrough green checkmark in the Modify ribbon.
5. With the Walkthrough path still selected, click the Edit Walkthrough button in the Modify ribbon.
6. In the Edit Walkthrough Tab on the Ribbon, use the controls to advance to the next keyframe or rewind to the previous keyframe.
7. For each keyframe, look to the Options Bar for some additional controls.  By default, Active Camera is the active control.  Other options are Path, Add Keyframe, and Remove Keyframe.
8. With Active Camera selected, look to the Properties menu to change Far Clip planes and Crop Regions.
9. With Active Camera selected, in the drawing window, click and drag on the pink control to change the camera's target position.  (what the camera "sees" if you were to look through the viewfinder)  In a 3D View, or section or elevation, use the pink control to change the elevation of the camera target.  (make the camera look up or down)
10. Switch the Active Camera control in the Options Bar to Path to modify the Walkthrough Path.  Click and drag one of the Path Grips to change the position of the path in plan.  Switch to a section, elevation, or 3D view to move the Path Grip vertically to change the overall height of the camera at that point in the Path.
11. Switch to a new view to finish editing the Walkthrough.
