I'm quite enthusiastic for freestyle vector exporting. I'm using it a lot mixing with freehand drawn elements or as base for freehand traces: geometrics, perspectives, blueprints, the possibilities are unlimited and it's awesome to switch point of views when needed. That's a great way to produce wonderful infographic elements. I will add freestyle tips to the poster very soon.
