Feature Request - Optionally draw also the viewable edges in the "Solid" modes about fstl HOT 4 OPEN

Do you have an example model where this occurs or a screenshot?

from fstl.

This is a part I am working on for 3d-print:

The cylinder is drawn for reference, to check if other the edge are proper aligned. My purpose was to visually make this check looking at the front view. However the front view is not useful at all due to the absence of edge strokes:

Shaded view is similar. Wireframe is usable but still (lot) messy:

from fstl.

I see, so what you're looking for is kind of a blend of the solid rendering mode combined with the wireframe but only for the faces that are currently visible?

from fstl.

Yes, exactly. The openscad viewer does something similar:

It is still a bit confusing due to the edge drawn inside the same "Macroscopic" face, but I think this is unavoidable. However the clean-up is enough to follow the cylinder edge. The example model is quite simple, in more complex ones the pure wireframe view become quickly unusable.
