Does SVG import accept the layer= argument, the way that dxf import
supposedly does? (I don't use DXF, so haven't checked whether the manual is
correct.)

The documentation at
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language
does not mention SVG import, so I'm not sure what is supposed to work for
it.

No, SVG has no layers. There might be the option to add support
for what Inkscape calls layers but that will likely be specific
to Inkscape.

See https://github.com/openscad/openscad/issues/2383 for some
details including someone who actually worked on the SVG spec.

It's in the user manual, and still unfinished as it takes
quite a bit of time to create documentation...

ciao,

Thank you for the pointer to
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/SVG_Import

There is no pointer to it from
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language

What other pages are there to the manual that are "hidden" by not having any
mention on the top page? I don't know what to look for if there is no
mention at the top level.

It would be nice to be able to specify a subset of an SVG file (by group
name or color, for example) for import, so that an SVG file with several
objects that are carefully aligned could be imported and then the objects
handled separately (with different height extrusions, for example).
Inkscape seems to implement layers by group commands in svg, so restricting
by group name would be the closest equivalent of layer names in dxf.

That is the Language Reference Section.

The top level page is https://en.wikibooks.org/wiki/OpenSCAD_User_Manual
and the SVG Import is linked there.

Yes, the specifically named (by non-standard parameter) group is
probably the best option. That's pretty much the conclusion from
the discussion in the linked github issue. The inclusion of
layers directly into SVG does not seem to have made much progress.

ciao,
Torsten.

Oops! Thanks for the correction. I had saved the link to the language
reference section, thinking it was the top level. I'm used to documentation
in which the language reference is complete and authoritative, with other
sections giving tutorials—it had not occurred to me that chunks of the
language were not included in the reference manual.
