Sheet Metal Model from apparently continuous surface

Why can't I generate a continuous metal surface from this model?
Even though I select the edges to bend, the software doesn't accept my choice, saying it can't generate the surface...

Got it!
But I managed to solve it in a "cheating" way...
I created a cone using polygons, not circles... This created a faceted cone. From there, the software understood how to join the faces into a single metal piece.
Thanks for the help, friends!
I hope the software development team at least tries to fix this, because empirically speaking, the operation was possible from the start...Cheers!

Because sheet metal doesn't allow non-straight bend lines. So it doesn't know how to deal with the cone I suspect
Maybe I can't generate a continuous surface because I'm using a cone in the composition, and cones can only be made individually, separately, so that's how the software understands it.
If that's the case, why doesn't it understand that a cone can eventually be made by hand, with a suitable hammer, etc.?
But the line I select to bend is straight…
The line I assume you're referring to is the one between the cone and the flats next to it. I'm able to select any other straight line and add a bend. The issue with that line specifically is the interaction between the cone and the flat requires the bend area to fall back into the conic bend area and the sheet metal features currently aren't built to handle a bend line interacting with a cone in this way. If you instead do a sheet metal thicken on just the cone face and attempt to draw a flange on that edge you'll get more clear errors than the sheet metal convert or sheet metal thicken workflow explains to you.

Is this what you wanted ? https://cad.onshape.com/documents/b315ba32555eac269558c21f/w/23f1d92ba10170ccbc857a78/e/f03fa8ee09b6afb0251484a6
In case of non-tangent planes you'll have to build the bend cylinder explicitly. Like this https://cad.onshape.com/documents/b315ba32555eac269558c21f/w/23f1d92ba10170ccbc857a78/e/61ce66369e80f76c9635af1a
Cool, this path of constructing a drawing is new to me...
I'll try and see if I can achieve a continuous surface, within my needs.
Thanks for the help!
Never thought of making a sheet metal cone this way. Thank you @lana
