I have published new free and open source tool which allows exporting SOLIDWORKS files to pdf, HTML, images etc. via eDrawings in a batch mode. Tool has a user interface as well as command line interface thus allowing exporting of files from the integration workflow.
One of the main benefits as you can use free eDrawings viewer to perform this operation and do not need SOLIDWORKS to be installed.
