Clean Up Current Model tool in the Purgers tool group of the Project Cleanup tool-set can help clean up various elements and types from the current model as opted.
When the ribbon button is clicked, the tool will ask for what to be cleaned up from the current model.
If some items are checked and the OK button is clicked, the tool will clean them up from the current model. A progress bar will show what is being done at each moment.
An information box will finally show up to report what have been done.
