Under Edit>Perferences>General ( click on word general) you can set the number of Undo's to anything you want eg 20 or 30 if you prefer . The is also a folder in you HD Data folder ( usually in My Documents) called Archives , which should contain automatic saves HD makes as you work on a file if you really need to "step back" from a major booboo. on the next tab of general ( above is file management and you can set the time between autosaves too ..eg every 5 mins. At least all these options are available to me On Pro10.

Accurate dimensions will make things easier for sure , and make it easier to make it look like the real thing.
