I find it a challenge to properly see the direction of normals when they use draw2d and appear on top of geometry.

I have in some extensions drawn 3D first in solid strokes, then used draw2d on top with a stippled stroke so that you get a "ghosted" appearance when the 3D stroke is obscured. I guess a transparent fill in 2d would also work...

Good idea!
Stippled or transparent would be with the same color as the solid arrow. So for (re)drawing the occluded part of the arrow I don't need to clip it, but can redraw the complete arrow. That's actually very simple.
