Hi Ivano,
The SVG exporter receives a set of strokes from Freestyle and tries to
generate a set of SVG filled paths. Hence it's important to tune
Freestyle parameters so that the generated Freestyle strokes are
favorable for the exporter to fill the corresponding paths without
trouble. Making sure that is in turn up to you who control the
Freestyle parameters.
Freestyle strokes can result in either open or closed SVG paths. In the
case of open paths, the SVG exporter is unlikely to be able to generate
the fills that you might expect. So, it's artists' responsibility to
make sure the filled SVG paths will be Freestyle closed stokes (i.e., a
stroke ends at the beginning of the stoke). In practice, however, this
is not a trivial task given the present set of user-tunable Freestyle
parameters, and that's where Freestyle needs improvements.

Hello everyone.
I tried to use FreeStyle SVG exporter with many shapes, edges are always
exported right, while fills aren't.
I just came with a solution: I guess the SVG Exporter doesn't use the
layers concept - not layers as I could mean with eg Gimp, here I mean
layers as in Inkscape (send to front/bottom, lower, raise, etc).
This could be why if an edge overlaps another the lower edge gets filled
weirdly (see here for an example:
https://blenderartists.org/forum/showthread.php?415556-FreeStyle-SVG-Export&p=3154988&viewfull=1#post3154988
)
But, in Inkscape (as well as any vector graphic editor) the 2 shapes would
be 2 different paths, with 2 different fill color (eventually gradient)
and, most important, they're filled right.
So, I guess the SVG Exporter "flattens" the exported paths to just one,
while allowing to draw each shape on its path and arrange the depth
correctly would make the difference.
Sorry for being so verbose, but I'm not a developer and I don't either know
if I'm totally right about this, just wanted to make sure you can
understand what I mean.
Please, let me know if I've been unclear or if I misunderstood anything, or
anything else.
Bye, Ivano.
