Is there a way to create a flange on the tab from a cylindrical sheet metal? I could have created a part for extrution but it won't let me flat the part for the strip machine to bunch it out.
You have to flatten the part before you add the tab. Then you have an extremely good chance that Solidworks will not let you roll the cylinder up again because now you have a double curved shape.
B.E.
You are judged not by what you know, but by what you can do.
A flat pattern can be created of the basic part, but will not include the notches.
The notches will have to be created in a separate config of the flat pattern.
That's currently a very sad limitation of SW.
