It is currently not possible to trim objects using the Break Line (created with the Break Line Tool) I would like to see this introduced, please.
I was wondering why my ears were ringing...
The Vectorworks Freebies page on my site as been "under construction" (or under pre-construction) for some time. While I still plan to work on the page, I went ahead and placed the Break Poly plug-in for download.
I just reworked the Break Poly plug-in and the "PanzerCAD Break Poly 2009" download should now work in VW 2009 and later. Please let me know if you find otherwise.

Enjoy! :-)
