You could also use a "master" scene that would reset the model when selected. And there is the File > Revert menu option, which will revert the model back to the state when first opened.
Checked my "file revert". My revert is grey out, and I haven't found any way to ungrey the revert. So what do I need to do to use revert?

Oops, never mind. Was looking at a file that I had not done anything to, so when I added a new section, saw that revert was not greyed. So, thanks for at least making me aware of the revert option, because I sometimes can realy mess up my work.
