Subject Dashed (or Dashed-dot) Line Symbology loses its rythem for polygon features 
Author Heping Zhan 
Date Sep 13, 2007 
Message This topic may have been discussed before. But when I symbolize a polygon feature layer with dash or dash-dot combo for a polygon layer, the rythem of the dashes/dots is lost when I get to sharp curves or corners. Or if multiple polygons sharing common boundaries, the rythem is normal in some sections but becomes a solid line in others. How do I get the symbology to follow the same rythem (without converting my polygon features first to polylines). Thanks

Message In 9.2 you might look at cartographic representations.

Message John, (or anyone else out there),
I finally got ArcInfo v9.2 installed and was looking for Cartographic Representation tool to test and see the result. I was not able to either find the tool, nor did ArcGIS Help provide an easy-to-understand information on how to use the tool. I hate to ask, but could you or anyone give me a straight forward and easy to follow intro on how to find the tool and how to set up a representation rule to resolve my original issue? I really really appreciate it.

Message Heping,

Did you see the following help topic, which I think is pretty thorough in discussing cartographic representations: http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=An_overview_of_representations

Message Thank you for directing me the the info on Representation. I went through the tutorials 9.2 provided and it appears that using cartographic representations still won't answer my initial question "how to make a dashed line representing a shared boundary in a polygon feature layer not to look a solid line?"

Anyone knows a solution? I don't believe I am the only one having this question. In AutoCad, one simple command line resolves that issue. I can't believe there is no solution to this in ArcMap.

Message What has worked for me is to edit the properties of the polygon's bounding line, adjusting the template.
Open the Layer Properties for the poly layer, then click on the symbol to open the Symbol Selector, then click on Properties to open the Symbol Property Editor, then click on Outline to open a new Symbol Selector, then click on Properties again to open another Symbol Property Editor, then click on the Template tab. In the Template tab, under Properties/Type, select Cartographic Line Symbol and then adjust the line pattern, the black and white squares. I've found that just adding one square to each "set" is sufficient - for example, if the line template defaults to 4 black, 1 white, 2 black, 1 white, 2 black, 1 white ... change it to 5, 2, 3, 2, 3, 2.

Message Thank you Tift Tax GIS for taking the time to assist me on this. I tried your method and it did not work for me. To demonstrate my point, I attached two snap shots of my screen. One "Results_Using_4_..." shows the result of applying your method. The dash patter works fine with the non-sharing boundaries (as seen on the right hand side of the map but not for the shared boundaries (as seen on the left hand side). I tested using a line Offset of 2 in the Line Properties setting and this made the shared boundaries look a lot better. But the side effect of using an offset is that you end up with a funny knot at each corner where the line turns direction (as seen in the other screen shot I attached).

Anyone has any solution to this? Thanks

Message Heping - I would get rid of the overlapping boundaries where polygons meet. If adjoining polygons share a line, the line should draw the way you configure it in the Template.

Message The polygon feature class I used in my example does not have any overlaps. To prove my point, I created a new polygon feature layer with one polygon and then used Cut Polygon Feature editing tool to cut the polygon in half (this operation is not supposed to create an overlap at the cut). Then I applied the dashed symbology and the result was still the same (see the attached screen shot and see the resulting effects on the yellow polygons' split line)

Message Beats me ... I use cartographic lines for our 95-polygon map grid, using the steps I posted earlier, and they look fine. In your examples, it appears that ArcMap is trying to draw 2 lines side-by-side where polygons touch.
If all else fails, create a line class from the polys, as you mentioned.

Message So far as much as I know, converting a polygon feature class to a line feature class seems to be the only way to solve that symbology problem (which is a pain). We thought ESRI's release of 9.2 would provide a smarter solution.

Thank you so much for your responses.

Message Hello!

Another way to handle symbology on the redundant(duplicated) polygonedges where polygons meet is,to create a twolayer-linesymbol with a solid bottom layer symbolised as the backgroundcolor of the map.On top of that one,you define the desired pattern for your boundaries.This approach will mask out the first edge when the second edge draws on top!
The discussion on commonedges,shared edges is not relevant, as no polygons ever share any elements with another polygon.The root of the problem is, there will always be two geometries for edges where polygons met spatially.In most cases they are coincindet, and appear to be shared!

Message Bengt,
I'll certainly give it a try when I get to my office next Monday.
Thanks for the info.

Message Bengt,

Wow! It worked. Instant improvement. Thank you so much for your suggestion. I attached a screen shot to show you the result of applying your technique. And I also attached a comparison shot before applying the technique.

I hope this is helpful for everyone out there who is struggling with this problem.
Again, thank you.

Do you have any transparency or BMP marker symbology in the map?

Message I have the same problem. What is a "twolayer-linesymbol"? From the jpg it looks like some kind of knockout, which I cannot use, because my map background is variable and complex. The dashed lines are sitting on top of many other lines.

Any further suggestions?

Message Two-Layer means that the line symbol consists of two layers, one a solid color band (in this case white), the second black dots and dashes. (Works the same way as a Highway symbol with outlines and a different color in the center, except here the center line is dashed and could even be the same width as the underlying "masking" layer.

To create a multi-layer symbol, open the symbol editor and click on the preview window. Now you can add layers and modify each one separately.

Hope this helps,
