**If** your CAD program has the tools to redo the pour then what you 
said below is meaningless which was the point of my reply to the same;

"I would also say the copper pour must be the last step in the 
process. All traces are finished and the board is basically working 
before i add a copper pour."

It's quite possible that all relevant CAD programs cause a pour redo 
when the board opens...Something like a reset. Perhaps the only 
difference with Eagle is that by default the redo doesn't take place 
automatically allowing you to edit in unfilled space first if you so 
wish. Otherwise, there would have to be a command to rollback the 
pour. Neither here nor there IMO.
