'Ortho' with edge rendering...

I’m trying to combine edge rendering (eint) with an orthographic view (ortho).

Without ‘ortho’, the edge rendering works nicely, but when I switch the camera to ortho, the edge rendering no longer works properly (only outlining the object, not edges within the silouette). I tried turning up eint, but this did not resolve the problem.

Has anyone experimented with this combination of settings?

What am I doing wrong?

To sort of answer my own question…

The number of edges rendered in ‘ortho’ view depends on the distance of the camera from the target. If near you see more edges. By getting nearer to the target you can adjust eint to an appropriate value.
