If I understand correctly from the severely short documentation page, the Freestyle SVG exporter can export a model to a SVG file using different styles:
-a series of volumetric lines, as seen here:
-outlines where the hidden edges are rendered as dotted lines, as seen here:
However, the documentation doesn't bother expanding on how these results were achieved. There are no modifiers in the Modifiers Panel, or in the Freestyle Export Panels, that seem to correspond to these examples (I looked in both 2.79 and 2.80).
How does one render 3D models into SVG, while applying the styles of these examples?
