OK I've been doing some tests with Sketch and Toon for Cinema 4D R10 and how well it outputs to Illustrator and Flash, checking for the following; Intersect, hiddenline, crease, fold, border, outline.
Here is the base scene file where we have one object intersecting, some creases, some folds. There are 3 materials; 2px thick out line, 1px intersect and fold, 1px dotted for crease. Giving us a standard technical drawing palette.

The following image is a parallel view technique with the camera adjusted to an isometric angle:

As you can see, hidden line and intersect are behaving badly.
The following is a standard parallel shot, Intersect & Outline are not working:

Isometric camera. As you can see, intersect isn't working:

Perspective telephoto, objects miniaturized, iso camera view angle:

And finally Perspective with everything working fine:

So understanding the standard viewport render limitations, I move on to exporting to vectors (invaluable to illustrators and architects), or web animation formats like flash. Exported using export to illustrator and Flash Ex2 render built into C4D:

perhaps not exactly related but I wanted to create once pixel perfect e-boy style renderings in 3dsmax and got issues as well:
anyway those tests brought me eventually to finalToon

though I haven´t tested it out myself the features are impressive - way more advanced than RAVIX (swift3d), illustrate or the other more common toon renders.
esspecially this particular gallery item:

implies that orthographic projection is no problem.
