A couple of days ago some asked how to model a basic looking sheetmetal part. SolidWorks can't often handle bends inside another bend region.

What looks easy to do is not so. That is if you want a working sheetmetal part, that gives you the folded & flattened state plus the parametric bend line info populated in drawings. Standard modeling practice will fail. SW can't either add the tabs, or the tabs won't flatten, or it won't mirror or you can't get the bend info. No uncommon SW sheetmetal limitations. Often times, even if you finally find a solution it is most likely unstable when you edit your design. But sometimes SW surprise you. It turns out, you can split the sheetmetal up into developable sub-section. Then combine all bodies in the flattened state. Here is the kicker! SW will keep track of the bend notes for you. At least it did in the attachment. Often time it takes a long time to model finicky SM models in SW just because of the kernel limitations. But this technique might get you bye in one or the other situation. The sample shows the principle idea. Maybe someone wants to model the part as per the info in https://forum.solidworks.com/thread/242198
