One would create outlines of each state by sectioning off and duplicating the geometry as necessary, and then using Join Vectors:
Select the outline:
and copy-paste it:
and then add the sectioning geometry to the selection by shift-clicking:
and use Trim Vectors:
to remove what is not wanted:
OK
Repeat for each piece of geometry:
Ok
Then select the geometry for the completed state outline (after duplicating any which might be needed for surrounding states)
and use Join Vectors to close:
Yes
If need be, repeat the operation:
Yes
which then yields a closed outline:
Repeat for the other 47 Continental States…
