SKETCH STYLE uses Freestyle for line drawing. It has a number of other benefits, including the ability to designate something NOT to be rendered in SKETCH STYLE (windows, photoreal features, etc…), as well a very quick to setup, toggle back and forth between realism and Freestyle, and saving Freestyle presets.
You could try using the Boolean Union modifier to create your intersecting object lines. I’m not sure what the story on LANPR is-- I know they’ve been trying to get as part of Blender, but so far I haven’t heard anything either.
Best of luck!
