Any way to get a render that shows profile edges?

I am fairly new to Unity, and so far I love it. I have been working on a few models in Sketchup and would like my renderings in Unity to look similar to Sketchup creations. I have tried the Toon shader but I have a few issues with it. Here is a pic of what i am trying to accomplish…

if anyone else has tried this or has any insights on creating a style like this in Unity is much appreciated!

Can’t view the images, but If you want to show an outline for your models, have a look at the outline shaders on the wiki or import the toon shader package from the standard assets.

Edit: Images show up now.
