It's fantastic that Renderworks is now included with Vectorworks 2017. Now all Vectorworks users can create great renderings right within Vectorworks, without needing to export to other applications (though if do want to take your renderings even further, Artlantis is amazing.)
If you are new to using Renderworks, or if you have some Renderworks experience but want to increase and solidify your skills, we highly recommend watching the following video playlists compiled by Vectorworks Inc.

As an aside, you may also find it useful to run Cinebench on your computer, as seen in the video below, in order to gauge your computer's rendering power.
