As long as I've been using SolidWorks (18 years), I have never truly understood how to create sheetmetal parts. I'm more of a plastics guys. I've only ever had a need to create a sheetmetal part a handful of times. And all of those were super simple.
Now, all of the sudden, I'm being faced with creating a sheetmetal part, that I believe would be a challenge for even experienced sheetmetal gurus. Basically, it is a tapered cone that wraps around nearly meeting itself, with partial flanges on the edges that nearly meet. I have struggled and struggled with this. But I can't seem to get what I need, in a true sheetmetal part.
I'm attaching a part model that I created (non-sheetmetal) that represents exactly what I need. It is actually a body inserted into a new part, as the original part model contained proprietary information. Plus, it was pretty ridiculous what I had to go thru just to create what is here (too embarrassing to let others see it, hehe). Also, this part contains a few holes and a notch. These features are NOT my biggest concern. My biggest problem is creating the tapered cone, with the flanges. I think what is hurting me the most is the gap of the cone feature (lofted-bend) that the flanges need to be on, will have a taper the opposite direction of the cone itself (refer to the reference sketch from the back view).
Could one of you sheetmetal experts please take a look at this model and give me some pointers? I don't even really know where to start...
