STEP File Blank on Export

[glencandle]

I'm totally stumped.  I have two components in my project.  One of them exports just fine. The other one just exports a blank document.  I've tried so many things (restart, clear cache, tweaked design, tried exporting further back in timeline, etc) but nothing works.

UPDATE: I dumbed down my project so I could export it. No more components, just two bodies. The top one exports with an issue (noted in a post below), the bottom one still won't export.  Project file attached, thanks!

Without the design in question, no, there is not much we can really do to help.  If you can simplify the design to the point that the proprietary information is removed, and the problem still exists, then we can take a look.  Without that, are there any differences between the two components?  Do both have a solid or surface body in them?  Are both visible?  STEP export will not export sketches, meshes, or T-Spline bodies.

I don't want to make my project file public because it is proprietary. Is there anything else I can do to try and diagnose this?  I'm worried 😞

At least show screenshot image of expanded browser (especially the Bodies nodes).

Something like this

To take a screenshot:

Shift Win S and Ctrl v into a Reply here if using Windows OS.

I assume there is a similar procedure for Mac OS.

(Or use your cell phone camera.)

Thank you Jeff.  I went back to a primitive state where the problem still persists and I can share the project file.  I have  also discovered something interesting along the way:

1) The "bottom" body won't export at all, just comes out blank.

2) The "top" body exports, but it doesn't export properly.

It is supposed to look like this:

 But instead it comes out like this:

I've done numerous iterations of this part, using the same sketch files, and this hasn't happened before.  Is there a chance my project file has become corrupted?  If so, is there a way to repair it?

Thank you for taking the time to look at this.

Thanks for sharing the reduced model, @glencandle.  Yes, there is definitely a problem here.  However, my results are slightly different on a round-trip export (export to STEP, re-import).  Both halves come back in, but they are surface bodies, not solid bodies as in the original:

second, as you noticed, the geometry around the blends at the corner are not right:

Finally, if I roll back before the Split Body Feature, the round-trip is fine.  So that split must have introduced some challenging geometry:

I will bring this to the attention of the translation team.  The results for IGES export are the same.  I did not test other formats.

Thanks Jeff, I appreciate you looking into it.  The only solution I've found is shrinking the size of the Fillet.

Life's a compromise I guess, lol.
