The sketchy lines should be overlayed to the shaded view. they should be treated like the existing outline feature.

Hello,

thanks for the sketch feature.
This should, instead of being a separate rendering mode, just be a permanent feature like the outlines.
You should merge these two features (outlines and sketch).
We really need the sketchy lines as an overlay to the rendered view!
The legendary "illustrate" plugin for 3dsmax could do that 20 years ago.

I had suggested that a while ago with even more interesting features.

Also the extended lines don´t really work. in my case it works just with two objects.

Best
Alex
