<p class="v1msonormal"><span lang="EN-US" style="font-family:"Century Gothic",sans-serif">I’m trying to determine if its possible to have QGIS render the exterior boundary of polygon features only once when that boundary is shared with an adjacent feature (don’t
render overlapping exterior boundaries for both polygon features). The data I’m working with is a county parcels layer and the symbology I’m using for this layer is a cross hatched line fill with a separate component for the outline of the polygons. I’ve
tried a couple of expressions (examples below) including one geometry generator and one data defined override for the stroke width of the boundary line but none of them achieves my objective. I’m using QGIS
<span class="v1grame">3.34.7</span> and my coding skills are limited. I feel like I’ve seen this issue covered somewhere but have been unable to find a solution after extensive online exploration.
