ArcView 3.1 Question
Posted 26 April 2007 - 08:37 AM
I have a question about how to do something in ArcView 3.1. I used to know this but it has been years since I last used ArcView 3.1 regularly and currently it is the only GIS tool I have at my disposal (that will change soon).
I am looking to export a number of polygons from ArcView to Illustrator as an eps. I fill the polygons and export the file from ArcView. When I open the file in Illustrator many of the polygons come in as vertical slices (dicing I believe this is called). Exporting the polygons without a fill results in broken lines that must be joined to create polygons. I've looked on the ESRI site for help or a script but to no avail. Sadly it appears that the world has moved on to newer and better versions. Can anyone help me out?

You are correct the results of .eps or .ai exports give unsatisfactory results. Unless someone has found a workaround (or script) I don't think there is a solution.
Only suggestion I have is to port your shape files in a trial version of a GIS package (e.g. ArcGis) that will do a better job (not necessarily a good one). You can also look up a MapPublisher trial (with MP the results are excellent).

We have found CutePDF to be very useful. It appears on your system as another printer, and writes to a file. The Pro version writes directly to PDF, and it looks like the free version writes to PostScript. You might already have a similar program from Adobe.
I don't recall the export limitations of ArcView3.1. If the dicing problem still occurs when printing to PDF, you can try a free GIS program like TatukGIS Viewer to set up your map.

Are you using export as NewEPS?

Exporting the polygons without a fill results in broken lines that must be joined to create polygons.
You can do it this way then use Rick Johnson's concatenate plug-in for Illustrator. Another trick would be to just export one polygon at a time to reduce the number of verticies - or you could export a raster and use LiveTrace in Illustrator.
It's been so long - I forgot if there was some other solution. The only thing I remember is that the Ai export never worked (unless you used Ai5).
Good luck and let us know if you find the workaround.

Well, you could . . . if you don't mind waiting. Anything I try to do with the Illy file takes forever.
can't you merge the polygons in Illy using the pathfinder tool? You could also try generalizing the polygons - since the banding is caused by too high node count (at least that is the case for ArcGIS)
Can you actually generalize / simplify in ArcView 3.x?

For generalizations, as well as other geoprocessing tools, I've relied on Analysis Tools by SWEGIS. That package is a bit pricey (although it's been some time and many revisions later). You might find other tools on ESRI's scripts page that will do the trick:

1. Downloaded a script to explode multipart polygons into seperate shapes (http://arcscripts.es....asp?dbid=11694 - that in itself solved much of the problem).
2. Downloaded a generalize extension (http://arcscripts.es....asp?dbid=10703) and generalized appropriately (a little experimentation required).
3. Exported to AI as EPS.
The export was not quite perfect - a few larger polygons were still coming in pieces but the outline was fairly intact and required only a couple of joins.
Thanks everyone for the help!
