Hello ,
I am trying to create sheetmetal ring with overlap joint as per attached image on the attached part but unable to do because of bead & vertical flange.
can anybody help on this ?

Thank you for the reply. you are correct. I dont want to add complexity for manufacturing.
So,I am not considering adding a bend flange to get overlap. I intend to use flat part rolled in to get the round shape and overlap to rivet it.
I understand to do it , the bead will need to be stopped before the joint as attached pic.
I can get round profile from helix sketch but then cant add bead and vertical flange . any thouhghts on it?
My thoughts... The swept flange can not handle a spiral or spline for the path (and we need a swept flange in order to include the flange and bead) so what I did here is to make the spiral then made 3 tangent arcs who's endpoints lay on the spiral. I was not able to include the overlap in this so I added edge flanges. Same rolled radius as the beginning arc so there is not another operation involved. I did have to do some hocus pocus on the ø.250 holes on the vertical (beaded wall). You might be able to come up with something better on the holes.
See if this will work for you.
Dennis,
Thanks for the response.It's almost there.I was wondering is there any way I can fill the gap shown in this image with continious sheet instead of Bead?
I can't think of a way to do that since when this is flattened it would have to stretch (severely) the continuous sheet. Also were you planning on making a tool (press brake) for the bead then rolling it?.. Or were you going to roll the bead by itself after rolling the rest? Or roll the vertical portion and bead and flange at the same time?..
I'm curious as to how you made what you have. Is it a sheet metal swept flange? If so I would really like to look at it to see how you did it since I was unsuccessful when I tried the sweep over 360°. I just may be able to learn something and that always a good thing.
Yes, I was thinking to have bead first and then brake and roll it.
For the model, I just extended the edge flange to get an overlap.
Looks like I may have to leave this model as is and for flat pattern I manually add flat sheet to cover enough overlap.
Have you solved your problem?
I'm thinking you may want it more like this, with joggles overlapping the opposite end. I did have to suppress your Fillet1 in order to get the part to flatten properly. Looks as though you started this model in an earlier version then saved it to 2017. That may be why I had to suppress the fillets. If you started this in 2017 that may not be an issue.. Don't know.. I was able to fillet the overlapping tabs I added and the part flattens without issue. Of course you can make a couple of configs for this and have the fillets in the formed model. and in another config suppress them for the flat pattern then add them into the flat pattern. Or include them in your cut extrude (funky) and so on..
I think if you really want the part to have the ends overlap and everything fit up nicely (without a joggle) (spiral like) you are asking for major trouble manufacturing it.
Edit:... Another OR.. Manufacture this the way you had it with ends butting up then add a splice (or no splice) for welding/spot welding/riveting ,,, This is an assumption on my part that you are intending to attach one end to the other somehow.
