I'm working in ArcGIS pro. I brought in a CAD polyline that I've split into a grid of polygons using the "feature to polygon" tool. It worked well except I need to symbolize the polygon layer with a dot/dashed line boundary which looks "messy" because of overlapping adjacent polygon lines (i.e. the line looks solid where lines overlap). I've researched the issue on this forum and elsewhere and am still unsure of whether it's a symbology issue (solved by some sort of masking) or whether it's a polygon geometry issue. Thanks in advance!
