The Reload in Batch command in the Component Families toolset helps users reload all the component families for some external project files.
After the ribbon button is clicked, a dialog will appear to ask file files.
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.
