You've mentioned two versions of the application: HOME and normal. The HOME version is targeted to single users that are working individually at home and don't need very complicated drawings. The HOME version is also limited to drawing file size up to 300 Kb.
Visit the following link to see all the features offered in the HOME version: http://www.allycad.com/homeversion.asp
Secondly, you should upgrade to version 8.0 since 3.6 is a very old one. You can do that on the same website.
