(OP)

I want to flatten the attached.
Notice the thick red line that depicts an open edge - the point is to have the corners bent and physically welded and polished (for stainless steel)
But Catia will not keep the geometry where the three radii meet.





RE: SHEET-METAL -
Trim corners / fillets as necessary and use unfold command to get flat pattern. Not perfect and you'll definitely correct flat pattern.
