Understanding Sliding

Object misplacement is often the hidden source of sliding in inserted objects. While the tracks must be correct, and users intrinsically understand that, users frequently fail to understand the importance of proper object placement, relative to the trackers. This tutorial tries to correct that. BTW, the sliding demonstration in the initial example was because the pyramid was intentionally located a bit below the field level. Objects *above* the right location are more easily detected, so objects that are too low are a common mistake.
