URGENT: Threaded Text on a Curve is not justifying properly - BUG?

thanks for all your help here -

to reply to the raised questions:

text does have a space between every 2 characters (there are thousands of characters). perhaps it is the quantity of characters that illustrator doesn't like - I have read various posts about bugs when too much text is inputted.

All delimiters are set exactly at edge.

It is only worse on the large segments of threaded text - on the small sections of threaded text it is fine and fully justified.

I have tried with a monospaced text- same result in fact worse.

Is there a way to transfer the threaded text as an object into InDesign? and input the text into there?

I would prefer to do this is indesign but I don't see an option for threaded text and I have many hundreds of these concentric lines so it is would be time consuming to say the least if there isnt an automatic function?

any suggestions warmly welcomed.

thanks!

Unfortunately I think the text has to be broken up into individual lines and applied separately to each path. That would be time consuming to do. Worse yet, to get the text to fill out each curved line properly each line would first have to be typed out on a straight line the same path length as each curved segment. FYI, you can see the path length of a selected object under the Document Info tab, with "objects" checked (it's un-checked by default).

I like using outlined text objects converted into custom brushes as an alternative to the typical text on path tools. Sometimes the end result is a lot more pleasing since the baselines and cap height lines will follow the curves of the source path. Standard text on path functions only rotate un-modified letters. The letters don't look like they "flow" with the curve. And sometimes the merely rotated letters end up looking pretty wacky. Lettering as a brush will look like it flows along a curve. Some really interesting effects are possible when combined with line stroke modification tools. I don't know how long a line of lettering can be contained into a custom brush however. I would imagine there is some limit. I've only used the procedure on logos and graphics using short lines of text, not big paragraphs worth of text.

Please post larger screenshots. Also: which areas are giving you trouble? I can't read the whole thing. Is there any space in that text or just letters?
