Why doesn't boolean difference work with this ring?

I used the Flow Along Curve command to flow the design and now I would like to engrave it. I tried boolean union but it didn’t work. Any ideas?

The polysurface is already Unioned together.
What problem are you trying to solve?
What do you mean by “engrave”?

This is already being discussed in another thread Susan posted in: Making surface details to a piece of jewelry

I mean subtract from the ring itself so that it looks like it was engraved
with the design. Does that help? Susan

You’ll need to remodel it so they actually intersect.
I posted a comment and image on the other thread that shows the problem.
