Flex issues with complex geometry

I'm trying to flex a linear structure into a ring and I'm having issues with the flex feature. I get a body with surface gaps (see picture).

Anyone have a better way to do this? Couple things I've tried:

Converting all features to a single body and performing flex (same result)

Exporting as a .STL, re-importing it, and performing flex (very very slow, but gave promising results on a simpler version that was giving me the same issue)

Exporting as a .IGS, re-importing it, and performing flex (the preview is exactly what I want, but the end result is the same as above). If only I could save previews...

Any help is much appreciated!

Correct Answer

Thanks for the input Paul, unfortunately even small bends cause errors.

After much trial and error, I did manage to resolve this.

I broke out features in my part to separate parts and applied the flex individually to each. This greatly simplified the geometry with each flex, and did not cause large errors.

I then imported and aligned all my parts into an assembly, and merged all bodies to get my part.

Bob,.. what I'd do is,.. before you Flex,.. run a Tools/Check.. note any faces/edges which are suspect... then, adjust your 369.93 degs back until it solves (say it's ~300 degs?)... again, run Tools/Check... note/cross check those faces/edges which are suspect... now try and fix them or make the boundaries around those areas more flexible.. that is, slightly move features/faces, add split lines, chamfer/radii, before the final Flex.
