I'm trying to make a multibody sheet metal part that has alignment tabs to aid the fitter/welder during setup. I came across a similar model (shown below) which was setup using the same idea, but I'm not sure how to go about doing it myself in the attached part file.
As you'll see in the attached model, I managed to get one of the tabs in the bend radius, but it disapears when I unsuppress the flat pattern. I'm not even sure I'm going about this the correct way. Any suggestions would be greatly appreciated.
Thanks,
Mike.
These are simple cuts and extrudes, depending on how tight your guys like the fits of these I would allow a minimum of a .005 gap on each end of the tabs. If using a turret, the cut extrude might be made with a .125 x .25 punch, the tab would then be .24 long. On a radius bend like this I would allow more, your welder may also file these off if they're thin enough and in the way. I most always made these with a half material thickness overlap and the tabs or tongues would be on the inner part 1/2 material thickness tall. The recieving cut would be 1/2 material deep then. This method offers a 1/2 material open corner for good penetration. If you're dip brazing the part, then I would go full materials as the picture appears to suggest.

Geez, I didn't even look to see that this was an old post!
