3ds Max Modeling :: How To Create Construction Lines

I want to create a animation like this with a very Engineering Drawing theme to it: URL....I have also attached two images (stills) from the animation.

The question is, how do I create the "construction" lines (i.e. the blue marker lines) that go beyond the models? Is this something I should consider doing in post?

My current approach is to use planes with textures of the "construction" lines and linked to 3D models. The lines would also look like marker pen/pencil lines.

An alternative could be to use lots of lines and make then render-able but then they would look too perfect and not pencil graphite or marker lines.
