Do you mean like this? Using sheet metal you can get the flattened blank correct with perpendicular edges, then use the bend feature.
There are of course so many ways this can be achieved.
Not like this one. Actually pls have look of image again from bottom and top.
Its a sem screw with washer if u want more pic of it
I was offering you a generic method as you stated
because i already had many sheet metal parts( not limited to washer or fastner) like this one
The image of the washer is clear and not something that is typical for the sheet metal application, this is more like a pressing.
What is the purpose for the model?
Do you design and manufacture these washers, or just use them in an assembly?
I have the same questions as Mark.
If you aren't manufacturing these parts, a representation is probably all you need. Otherwise you are cluttering your assembly with non-essential geometry which can add up if you are including a lot of these in an assembly. "Add up" as in graphics rotation calculations, drawing view generation, etc.
Similar case is those users that feel they have to model threads on hardware..just because you can doesn't mean you should!
