Yes, that is the way it was intended to work.

I intend to have xcircuit draw partial selections, but I have not
got around to it yet.

Yes, you can. I have used it in the past for similar things, although
I forget now what my application was.
To get points on a single polygon:
1) select a polygon in xcircuit
2) from the console or a Tcl script, do:
polygon points
To search through all polygons on an xcircuit page, you need a more
extensive script:
foreach h [object [page 1 handle] parts] {
if {[element $h type] == "Polygon"} {
set plist [polygon $h points]
puts stdout $plist
}
}
That should get you started. Unfortunately, I don't have a way in
xcircuit (maybe I should) to "tag" individual elements, such that you
could mark only the lines you want to extract. One suggestion for a
simple tag, though: You can change the color of such lines from
"inherit" to "black". For a selected element, the difference is:
color [element handle] get
returns "inherit" or "0", depending on whether the color is set to
"inherit" or black.
