Question
Why don’t I see the design option tab in Revit LT?
Answer
By default, Revit LT disables design options. To enable design options, change the setting on the User Interface tab of the Options dialog.
When enabled, design options work in Revit LT as in Revit.
If you use Revit LT to open a Revit project that includes design options, but design options are disabled in Revit LT:
You can change view settings to see the different design options that are available.
You cannot create, modify, or delete design options.
You cannot change the active design option.
