The stroke only on inside option would be useful - but for dashed/dotted
lines you would still get undesirable results because of shifted dashes,
due to different line-length of the polygon borders.
So the only two options I see is Stephans solution - which works fine as
long as your map background is white anyway, or to make sure that the
double lines are eliminated, achievable with a number of tools (but not
very dynamic, esp. for large data that changes a lot).
Or, the third option would be to use a topological data set from the
start (e.g. GRASS data a topological Postgis tables).

Hi.
and what about using the "Draw line only inside polygon" option?

Thanks David although we are using live data. Stefan’s approach is a
good one so I think I will continue with that, thanks for everyone’s
responses

Here is another solution that would work if you are not mapping live
data, and you can use a derived product. Convert your polygon dataset
to lines. The, use Vector>Dissolve to remove duplicated lines where
they are overlapping.

Hey Stefan,
Neat trick/idea with the white line. I’ll have to write that one
down. Hmm, I wonder instead of white though, if you could convert
that to transparent as well . . . .

Hi
Put a white line under the dotted line („Add symbol layer“).
Perhaps there is also a solution with the blending modes?

*Betreff:* [Qgis-user] Dotted line symbol in QGIS
Hi
I have a boundary layer that I want to symbolise with a dotted line.
The outer boundary appears ok, but where two polygons are adjacent to
each other, the dotted line becomes virtually solid (indicated below).
How can I make these lines appear the same as my outer boundary lines…
Thanks, Chris
