I can create a thin polygon representing the shared borders by:
- remove spikes and slivers
- buffering and clipping
Question
create line from shared polygon borders
Is there a recommended way of creating a line from the shared border of two polygons.

Hi,
There may be several approaches. I would use the Intersector and the Tester after removing spikes and slivers.

Intersector -> Tester (filter the line if "_overlapes" is greater than 1)

Intersector might be used.
I often find that this creates bad objects if used straight on the polygons..
U might consider:
SpatialRelator "touch" and test for related_canidates>0 to limit to touching polys.
Then coerce the polys to (poly)lines.
Then LineOnLine overlayer (or Intersector).
test for overlaps.
