The Setup Tab
This is the Setup Tab (Sequential UI Mode):

This is the Setup Tab (Non-sequential UI Mode):

This tab provides access to OpticStudio's Setup features. This tab is used when you start each design project, and is visited infrequently or not at all after initial setup.
The System group puts everything to do with basic system setup in one place. OpticStudio Preferences lets you customize the OpticStudio installation, folder locations, quick access toolbar, etc. and save these settings to a project configuration file.
The Mode group specifies whether you are working in Sequential Mode or Non-Sequential Mode.
The Editors group gives access to the spreadsheets that are used to define the optical system on a surface-by-surface (Sequential Mode) or object-by-object (Non-Sequential Mode) basis.
The System Viewers group gives access to the layout plots that are used to view the optical system itself.
Diagnostics lets you check the OpticStudio file. The System Check utility traps many common setup errors.
Windows Control defines how windows in the OpticStudio workspace behave. Windows can be docked, freely floated, tiled, or cascaded. Windows can also be locked or unlocked here.
Configuration is used if the design has multiple versions, which is typically the case for zoom lenses, thermal analysis of lenses over a range of temperatures, scanning lenses and lenses with moving parts. The Configuration group appears on all tabs if more than one configuration is defined.
