Does anybody know what the maximum number of points per path is in Illustrator? 32768?

Seems like it - I thought I had seen it in a post here somewhere - but here is another source/indication:

The figure 32000 is mentioned here as well: http://www.avenza.co...patial0503.html

32,000 - I don't think i've ever got that far.

What are you using it for Hans?

I'm setting up an Illustrator/MAPublisher training course where, in one of the excercises, I import some contour lines and MAPublisher says some of them were simplified because they had too many points. So I'd like to be able to tell my students exactly how many points that would be

I have ended up with that ceiling when exporting the unbroken Eurasian coastline.

(Interesting side-issue - Is the (north + central + south) american coastline longer? The number of points depends - of course - on the detail and number of fjords and folds.)

I have ended up with that ceiling when exporting the unbroken Eurasian coastline.

On certain levels of detail, places like Norway and Russia hit that ceiling. Usually I pre-process my data in FME and limit the number of points per object to something like 10000.

Hans - how does FME split up the polygons then? bands?

Hans,

You might be able to get at this number by selecting one of the simplified lines in Illustrator/Map Publisher and then selecting Object >> Path >> Simplify. If you check preview you will be able to see the total number of points currently in the line.

Bands and blocks generally.

Hi Hans

Here I have generated a China bdy file with exactly 58349 points in the shape file. Actually I had exactly half the points of this file in one China bdy file, so I have added one point in the middle of two by calculating simple mean. Thus doubling the points. Try importing this file by Map Pub and you will get the answer, hopefully..

Best..

32,000 is the number. I can't find any official documentation, but I've run across it enough that it's etched in my brain. The Oregon coastline at the scale of our corporate data (1:24,000) exceeds the limit when I import. My usual solution is to substitute smaller scale data. If I simplify, I prefer to do it on the GIS side.

Ah, importing...I guess I have got that far...but just always went with the simplification.

I thought you were creating a 32,000 point line/poly manually...whew, that'd be a lot of clicks.

Hans,

Check with David Andrec at Avenza. It seems to me he gave that number at a training course and may know the exact number. I'm also wondering if the number may have changed over the years is we've progressed from AI 10 and MP 5.

The point per path limitation in Illustrator is 32 000. This applies to all the latest versions of Illustrator including CS3.

In cases where data is part of a compound path and then imported into MAPublisher, it will be acceptable that there are multiple paths equaling higher than 32 000 points per path.
