It is an actual part to be used in a weldment. The piece itself has been made before from a 2D drawing. I am trying to model it in vanilla autocad and put everything into a 3D assembly. Really not required, but kind of nice to have. I have learned a lot from this site and figured that if it is possible to do the model, someone here would know how.
I gather from your info that you have the flat blank known, and the formed part is not so known, and that the fabricators just 'make it work' and it 'has worked for years' so it shouldn't change in their eyes. I used to work for a place that had a lot of historical part designs that weren't great... they were something rigged up in the shop and then just made the same way ever since, just because it 'worked' but I want you to keep in mind that revising old parts can often lead to drastically reduced welding times and therefore costs. Eliminating welding in any job will make the biggest difference.
With that said, I am attaching the following file.. it's not made to the dimensions you supplied, because... well it's just quicker to sketch the geometry for illustration's sake. Look what I did each step, I copied the part over every time I used a command to show a 'step by step'
Without knowing the Inside Radius of your bend, though, I just made it as an impossibly tight bend... rotating the bend flanges right on the bend line... in reality the steel is going to stretch a surprising amount with a radius probably between 3/8" and 1/2" or even greater, depending on the dies used (if you're using a brake press... if you're torching and bending in a jig... it could be anything... if it's a folding machine... uh... dunno)
Let me know if you have any questions.
