Try adjusting the offset of the symbol you're using as the decoration. In the line editor under line decoration properties, go into the marker symbol properties and adjust x until the edge of the symbol is in the crosshairs. Circle at default: [ATTACH=CONFIG]29393[/ATTACH] Circle with x adjusted +7 [ATTACH=CONFIG]29394[/ATTACH]

Thanks for the response! I tried that, and it works great...but of course now I have a new twist. Some of the construction projects cannot be dissolved into a single feature, because I need to uniqely symbolize different parts of the project. If I apply symbolization to the layer like you describe, I end up with a border around every individual feature within the project, instead of just around the overall project. Here's another example with two construction projects. Any takers? Something like this? Where the green and purple are different parts of the same project? (I took the liberty of modifying your screencap.) [ATTACH=CONFIG]29391[/ATTACH]

Oh ok. You did it right but I misunderstood your problem. Sorry. 😕 I don't know how to exclude the exterior borders in this case. Maybe some fancy footwork with topology rules? I'm a little surprised nobody else has chimed in yet.

You have the right idea but instead of using a second layer in the TOC you want to add a second layer to the symbol itself in the symbol editor. [ATTACH=CONFIG]29363[/ATTACH] [ATTACH=CONFIG]29364[/ATTACH]

Yup that'll work just fine. That means you can ignore my second paragraph about using two copies of the layer. Just use the one copy in the TOC and follow the instructions in the link to set up symbol levels. This is identical to the kind of task they use in the example, where they style polygons to only show the border where it changes. 🙂

The local city or county might already have that. It's common for jurisdictions to link addresses and streets. For example we have a tool created by the county GIS department which zooms to and selects a property when you type in the address, or returns an error message if the address is invalid. That's slightly different than generating a list of addresses based on the street but it would work in a similar way, based on the same sort of link between streets and addresses.

I believe we have found the issue. A coworker and I have been going back and forth editing shape files; I am using Arcmap and she is using Autodesk Map 3D. After exporting the shape file as a new shape file, and replacing the links, everything seems to be working ok. If anyone has any other tips, tricks or experience going back and forth between the two programs, I'd love to hear it. Thank you for your other suggestions. Ah ok. I've had issues with Map 3D corrupting shapefiles so I avoid editing them from there anymore.

Not in this case, as it disappears from the attribute table as well. The OP says it disappears from the drawing but is still in the attribute table and he can select it from there. I've experienced this problem when I edit points. The first time I ran into this, I must've added the point four or five times trying to get it to draw before I realized it was my symbology. Then had to go back and clean up my attribute table.

This help topic shows how to use symbol levels for this. http://resources.arcgis.com/en/help/main/10.1/index.html#//00s500000025000000 To keep the thin lines between polygons of the same value, put a duplicate copy of the layer in the TOC and style it transparent with the thin border.

In the same vein as the definition query, it might be a symbology thing making it invisible. If your attribute is a different value than what your symbology draws and you have unchecked 'all other values' from showing up then it would be invisible.

When you say the regions are based around a central point, do you mean that the point has to be the centroid of the region or simply that the point has to be within the region? I don't think there is one configuration of regions that is "the" correct configuration as is the case with Thiessen polygons. Gerrymandering comes to mind as evidence for there being many/infinite possible configurations. However thinking about this as a volume problem and not a population problem may help. Or maybe not. This is based on some distant memory of integral calculus on surfaces, so take it or leave it. (If nothing else maybe you'll get an idea for new search keywords.) Imagine a raster of Colorado where the cell values represent population instead of elevation. The cities are peaks and the rural towns are valleys. Then the problem is seeking region boundaries to yield five areas of equal "volume." I'm sure integral calculus has provided a way to do that by starting at your five points and integrating outwards until they meet each other. That would yield boundaries with the smallest perimeter...or...something like that. Whether ESRI has provided that tool, I couldn't say.

A little late to the party, but here all the same. The solution is to have two data frames. The DF that has the data drive pages will be 'off screen' and DF that has the static extent will be on screen. Screen shot attached. [ATTACH=CONFIG]28340[/ATTACH] Thanks for this idea. I never would've thought of using a page definition query across data frames.

Instead of proportional symbols try graduated symbols. The differences escape me but graduated symbols let you manually set the breaks. Alternatively you can abuse pie charts. Select only one field so that you get a circle that is all one color, and tell it to vary the size based on a field (quantity of rock sold). That should get circles that are proportionate to each other.

Nice map! It looks great. Out of curiosity, does the data count traffic in both directions AM and both directions PM? Or only in the direction of interest that matches the arrows? Depending how technically savvy your audience is, if there is no narrative context then it could appear to your audience that they only counted the people going in one direction in the morning and the other direction in the evening.

Something like this? [ATTACH=CONFIG]27698[/ATTACH] I can think of two ways. The first is to make your charts static symbols to use in Multiple Attribute symbology. Make the pie chart symbols in your favorite image software (I made them quick and dirty in Paint) and save them each individually. Stylize the layer based on your three fields of Water, Sewer, and Gas. Using text or number fields does not matter. Click Add All Values so it gives you all the combinations. Then assign the correct image of the pie chart to each symbology value. (You can tell it to make the white background transparent so only the pie chart shows up.) The disadvantage is that you can't change the colors, etc unless you go back into the image software. The advantage is that it's intuitive to organize the data. I think this method may only work on point data. More complicated but if you really really want to use the pie chart tool you can fudge it. You need redundant attributes so there are six fields instead of three. You would have Water Yes with values one or zero, and Water No with values one or zero. Same for sewer and gas. Be very careful that when the data is updated for new utility hookups that it gets entered correctly so that the ones and zeroes are in the right columns. Then the pie chart tool would read all six fields and only draw slices for the fields that are not zero. It would result in three slices from six fields and the color of the slice would depend on whether the utility was hooked up or not. So for example: Water Yes - 1 (blue) Water No - 0 (gray) Sewer Yes - 1 (green) Sewer No - 0 (gray) Gas Yes - 0 (yellow) Gas No - 1 (gray) This would result in a pie chart with a blue, green, and gray slice because it read 1 for water, 1 for sewer, and 1 for no gas. The advantage is it's easy to re-style the pie chart colors any time. The disadvantage is that six fields are more confusing than three and there is a high chance of user error for anyone editing the data.
