Hi,
If you want to have true lighting effects on the sources as well as walls, etc.. then there is only one way I know of doing this with a Sketch effect. The Sketch Render in ArchiCAD cannot do it. I don't know of a way that it can make the light sources work. But, you could render it in the Internal or Lightworks Engines, and then use this software to convert it to a sketch:

It can do both Black&White as well as color. It's a nice tool to have anyway. Is available as both a plugin for Photoshop or a stand-alone tool.
I'm sure there are other methods too with 3rd party software, but not solely ArchiCAD.
Best,
Foster
