Symbol levels not working with the Illustrator export

[KevinLECOCQ]

I use symbol levels to represent different overlaying lines by importance from a field value.

The red lines are more important than the yellow ones and have to be on the top. That's what I get in ArcMap:

And now that's what I get after an Illustrator export:

Symbol levels are not respected as yellow and orange lines overlay red lines.

I use ArcMap 10.2 (I don't know if the problem is still in 10.3).

I observed that this problem happens randomly. PDF and EPS exports are not concerned by this issue.

Here are the symbology and symbol levels properties for the layer:

Kevin,

As far as I know symbol levels are not retained when converting to AI...you will have to re-order the features in AI, put each level on a separate layer in AI, or break your lines at the transition end points.  The PDF and EPS "look" correct since they are simply a rendering of the actual vector line data.

Thanks for your reply Kyle. What a pity that symbol levels are not conserved by the Ai export. I thought Ai export was supposed to be WYSIWYG with the ArcMap rendering. Do you know if this issue is solved in 10.3?

I agree with alternative solutions your propose. I resolved separating symbols to layers or re-ordering colors with an Ai ExtendScript.
