Batch Transport tool in the Transporters drop-down helps transport miscellaneous families (styles) from the current model to some external files in batch.
After the ribbon button is clicked, it pops up a dialog for file picking.
Then the following dialog will appear to ask for what to transport.
If the OK button is clicked, those chosen families will be transported accordingly into those files one by one. A progress bar will show how many files in total, which file is currently being processed, and what remaining time may be. An information box will finally show what have happened.
