The
Save Plan As command is located on the File pull-down
menu. 
After your plan has developed to a level where you want to
create different versions or scenarios, use the Save
Plan As command to create a new plan file. This method provides
a good safety net for experimenting with Icovia tools or design possibilities.
The Save As command does not replace a saved plan under a new name.
Saved plans remain in tact, and a new file is created with the new name
given. So if you save a plan called Bedroom1, then do a Save
As and give it the name Bedroom2, your account will have both plans available.
Bedroom2 will look exactly like Bedroom1 did when you invoked the Save
Plan As command.
