Layers 13-extension and 14-extension each contain two objects. On each layer, try unioning these two
objects together. Then find and fix the anomalies that arise.

Create a few bugs yourself. For example, copy some objects a long way away by moving in a
perspective view where the horizon line is on the screen. When you use the "Fit" command to see such
objects, along with their originals, form•Z will appear to render nothing onto the screen. How would you
fix this bug?

When you are creating these bugs, start off with something you know about how form•Z works and try
to create a situation in which this knowledge gets violated.
