It is a big stretch, to me. You apply the word "line" in all sorts of creative
and metaphorical ways to various activities, which is fine for us -- that is
how humans think -- but the challenge of AGI is figuring out how to get
computers to do those things. It doesn't do any good to suggest mechanisms
that require general intelligence just to use...
And besides it is far from clear to me that implementing an artificial
intelligence using some literal sense of "lines" is necessary or even a good
idea. To be convincing you have to at least give some indication about how a
computer program would go about doing it.

Certainly! This is much more sensible. Brains do in fact have at least one
extensive and complicated mapping system (google "place cells" for more info,
and I think the various native coordinate systems used in the brain could
possibly be put to similar generative use). My personal tentative belief is
that at least some of the "basic" concepts underlying our conceptual system --
image schemas and other foundational general/powerful things -- are laboriously
abstracted in early childhood from these hardwired special-purpose brain
circuits (possibly some have, in a rudimentary way, been "compiled" into the
genome to make that easier). Another example could involve abstracting the
so-called "object file" which our brains use to keep track of important objects
in our environment... perhaps the whole "object" concept starts from there... I
don't know how this would work (yet)... Jean Matter Mandler has a theory she
calls Perceptual Meaning Analysis which looks promising and is pretty close --
but too vague for engineering use.
