Need help with unfolding detail with sheet metal

VSPOU — Tue, 22 Feb 2022 09:24:20 GMT

Hi, I am new to Fusion
I turn to you guys for help. To produce such a detail (see screenshot) by cutting on a laser, I need to make a sweep. I have no problem with this in SkethUp, but I want to learn how to do it in Fusion so that the program calculates the correct parameters for the sheet metal bend itself. I myself have tried many options for building, but nothing has worked. Can anyone explain step by step (may be with video) how to properly model such a sheet metal shape and properly unfold it? In the example in the screenshot, I tried to simplify the task, but even so I can’t do the unfolding. My workflow is to make a model, convert it to sheet metal, and then try to unfold it. I can’t draw with sheet metal right away, because I don’t know the angles to which the part needs to be bent. I do not rule out that my approach is wrong, because I still do not know the program well enough.

It looks like you have bends intersecting at the corner, Mostly 3D sheetmetal CAD does not like this. You need a relief big enough that the bend extents don't touch.

I also tried to make this shape in the corner where the seam is but in that case I get an error when I try to add the thickness of the part (0.7mm steel)

According to the video tutorial, I managed to make such a detail. But, the detail that I really need is different from this one. And I don't understand how to use the acquired knowledge to apply it to my detail.

Don't take it as spam; This is my first time posting on this forum.
This is the detail maded in SkethUp that I need, with all the dimensions and with unfold that should be in the end.

Thanks Carl,
Your model has helped me move in the right direction. The biggest problem is in the corner where the seam will be and where all the bends converge. I think if I try harder, I can bring this place to a more beautiful view. But even now, I think it turned out well.
