I need create some Undo list for use along the time.
Ex:
The (undo event) return for the begining of last command used and undo the last command, this is the rhino behavior.
So, I need every time I want press a button on my plugin save the undo state at this time, with this create a list (sort of backup) to at any time define the point where I want to restore my drawing
Something like this:
Any solution?
Thanks
