Panel (Arc) to be rolled, Bent, thickness?

Is it feasable for you using a (curved) GENSEC instead?

yeah, thats also another option, but some client "thought" pane used in fabrication is a flat panel that needed to be rolled.
engineering modeling design has no problem using it, but when it come to fabricator, they wanted to be easier to all flat panel to be element pane so the MTO extraction is the same. yeah. if u see my OP, there is gensec used Circular Hollow Section (with Negative element to cut it)

I have had this same issue many many times and very recently.
Currently E3D does not provide a solution for this AFAIK

The workarounds that I use mess up the MTO

I think only "marine" have buttons for it, but you can create bent plates via command line
