SmartPurger is a batch and script utility for processing multiple AutoCAD drawings with full control. Execute LSP or SCR files on multiple drawings. SmartPurger handles crashes so the AutoCAD batch processing continues to the end and leaves bad drawings to be corrected manually if needed. Many purge and cleanup settings are available.
The free trial is fully functional except that you can only batch process 10 drawings per session to give you the chance to confirm that the program works as expected. When you purchase you can use SmartPurger with no limitations.
