This is why you'd have to split off the flange of your part, and just look at the cylinder portion with the oil grooves. Anything more complicated than that results in hard math, and the engine won't like it. Essentially, if you're bending a flat strip, then the inner face gets compressed, and the outer face gets stretched a bit as you bend it. You can read up more on the specifics, but here's the quick overview.ġ) Thickness: When a sheet metal part is created, it's assumed that it's cut from a sheet of consistent thickness, and the sheet metal rule uses a parameter named 'Thickness'.Ģ) Material deformation: The sheet metal engine has a very limited ability to be able to stretch/deform material. There are a couple of caveats, if you're not used to working in the Sheet Metal environment. That's the only workflow *that I'm familiar with* that will let you create a Flat Pattern of a part. JD's suggestion is based on using Sheet Metal tools.
