I would be helpful if you could include screen captures of what kind of Illustrator graphics work and which do not. Are thttey all saved in AI format?
You're inconsistent in the way you describe your artwork. Sometimes you talk about graphics that have images in them and sometimes you do not:
"Some of those graphics have images and vector art."
"But still - why the <bleep> won't ID wrap around these filled vectors in the Illu graphic?"
I have no problems with any of the "filled vectors" I created in Illustrator. Text Wrap panel with Detect Edges and Wrap Around Object Shape works on them all:
But if you've embedded images, I'm not sure. I usually place vectors from Illustrator, and place images separately. That's why you need to show us your artwork.
here's a version showing the path I added to serve as a fence - I recolored it red and dashed it for visibility. In the previous graphic it is there but stroke and fill is the 'almost white' I described in my first post. ID did not see that 'almost white' filled vector. So- is it visual contrast ID is looking for, or are there other factors?
if you want to support InDesign's detect edges feature with an extra layer, I think this layer must contain solid filled shapes of black.
After edge detection you could turn off that layer.
That all said:
It seems that it would be easier with this kind of graphics to draw a new shape in InDesign and apply text wrap to it.
"turn off edge detect" - then the text runs through again.
No, this feature does not work well under these conditions. Oh, well.
