My older version of Inventor (2010) doesn't have any CrossBreak command.
Apparently the newer versions don't have it eitehr.
This is what comes to mind:
1. When doing platework, I would do this the hard way (manually) by using wireframe geometry with a slit along one of the breaks (to be welded), b/c the fab shops around here don't have the presses to make true true cross-breaks in plates. It's a lotta work to create this.
2. If the shop DID have the capability to make true CrossBreaks, then I probably would make an iFeature and use that in the model. It's a bit tricky, b/c of the variety of edge conditions this feature would need to accommodate. I'm going to try to do it and see if it's possible. I abandoned iFeatures many years ago b/c unless they're real simple and use the most basic features, they fail on me every time. Maybe I just don't know how to make complex iFeatures?
3. Also, to make a true CrossBreak you can do it the hard way and make the feature first, and make the sheetmetal flanges afterwards. See two attached examples.
4. I noticed that the SW sheetmetal CrossBreak feature is not really a true cross-Break. This can be done in Inventor using iLogic and some VBA programming. Or it can be done manually like JD shows, using Inventor's CosmeticBendLine tool in the sheetmetal flatpattern module. But these only work in the flatpattern, so you'll have to make another sketch in the folded part module to get the appearance of a CrossBreak on the folded model in your drawing. You have to 'Include Sketches' in the drawing to see those sketch lines. They don't work in the ISO views in my version of Inventor. Don't know if that's fixed in newer versions.
Here's a quick tutorial on iFeatures, in case you've never used them:
