Just in case I am reading your post right....
I am interpreting 'vector art' as 'wireframe representation' of the model.
PWx cannot (as far as I know - I am always careful to throw in that disclaimer) do the specturm of 'non-photorealistic' renderings that Penguin can pull off.
But it CAN render wireframe representations of your models, or hybrid wireframe/shaded versions of your models.
The option is under the 'hand-of-God' icon on your PWx toolbar (tooltip shows it as 'options') under the 'Advanced' tab. You can choose to 'render model and contours' or 'render contours only'.
Warning about rendering 'contours only' (wireframe) - for some stupid, stupid reason, if you just want to render or animate a wireframe of your model, PWx still has to calculate everything else that would go into a regular rendering (reflections, refractions, indirect illumination, shadows, etc) only to throw them away before making the wireframe (contour) render. If you are using PWx for wireframe renderings/animations, turn off all the lights, turn off shadows, and turn off all reflections and refractions (in 'document properties' under the hand of God) - this way PWx won't calculate stuff that it will just throw away anyway.
And, of course, if you want to make a wireframe animation, you might just want to cut out the middle man and set up anit-aliasing (both with SWx and your video card), make your SWx environment wireframe, jack up your screen resolution as high as it will go, and animate your SWx screen.
