A new Revit addin from Dima over at dp stuff can do that – it looks like this:
The tool is pretty straightforward, so I will try to describe just in a few words how it works (the demo video in the beginning of the post shows it as well). – assuming you already installed the WorksetExplorer, run the tool from dpStuff Utils in Add-on tab. – the dialog box will open and in the “tree” your elements will be sorted by workset, then by category, then by family, then by type. – every “branch” will have a name and the amount of elements on it in parentheses. – once you see something that shouldn’t be on a particular workset then you can select the branch and click “Select Elements” button – that will add elements that belong to this branch to selection. – now you can send them to the workset they are supposed to be on. – repeat until all worksets are in good shape. You can download the WorksetExplorer add-on from our download page or directly from this link.
thanks for share...
