Sheet Set Manager
This plugin helps you to easily manage your sheet sets.
In Basic View, you could save, save as, rename, or delete a sheet set similar to Revit, the difference is the "Hide un-check" button.
In Schedule View, you could manage your sheet sets by using a table and filtering sheets based on their parameters. This is very practical because most of the time there are too many sheets and it's hard to select the desired ones. And as a result, the probability of mistakes in selection sheets will increase.
In this view, also, you could edit, rename, duplicate, or delete sheet sets, or create new ones easily by using the mentioned filtering feature.
A trial version is also prepared for you to test the app, you can find it under the BIMODEL apps.
