So, I have some updates on the Issue. I contacted my local reseller regarding the issues with me trying to complete the examples on the manual page. They were not able to follow the examples, and contacted Graphisoft on the Issue.
Graphisoft replied that indeed the examples / instructions on the manual page were outdated and said the instructions will be updated so that they correspond to present functionality.
One issue was that the editing plane command "offset" is not in fact selectable once one begins editing an element. The local reseller said that Graphisoft would put adding the offset functionality while editing into consideration for further releases.
Another functionality that I personally would rate pretty essential is that of locking the edit plane so that it does not reposition itself after every editing click.
I guess we'll just have to wait for Graphisoft to consider these release-worthy functionalities for now.
