The Design Options tool lets architects and space planners create multiple layouts based on the same original program. Each space in each layout requires its own set of Actual Area and Count. It supports enabling and disabling Design Options in the Program Manager dialog. When enabling Design Options, a Design Options Settings Tab and Design Option files Tab gets dynamically added in the Program Manager dialog allowing you to add two or more design option files. When disabling Design Options, all the Design Option Tabs are removed from the Program Manager dialog. You can place spaces in the design option file and perform validation only for the current or all design option files at once to compare the Required Area, Actual Area, and Count results.
