As to your question, I'm going to assume you are talking about APE for ZT1. If so, then this file has not yet been uploaded, and neither has the file that allows you to do buildings. Admittedly, I know nothing of ZT1 designing though, so hopefully someone who does will be by shortly.
If you are talking about APE for ZT2, then its just a tutorial, and of course only applies to animals.
