If I perform any operation like cutting in flat pattern of sheet, the operation is done but it is not
visible in model .
As you can see in your model, the cut feature is after the flat pattern feature. By design, any feature after the flat pattern feature is automatically suppressed when the sheet metal part is in its bent form. To get the cut feature to show, you must first create an unfold feature to flatten part, add your cut feature then add a fold feature to "re-bend" part (all above the flat pattern feature of course).
The image I attached is just for understanding .
Actually I need t know that is there any way to visible the operation perform in flat pattern when it unfold.
Sorry, I do not understand your question. Can you provide screen shots of what you mean or rephrase question?
He wants to know if it is possible to see the action performed within the flat pattern, which is basically what you showed him, you just showed the bent version instead of the flat pattern.
I think he doesn't understand the roll-up bar and the whole supressed/unsupressed feature thing.
Language barriers, eh?
That is what I get for not doing step by step example.
It would help people diagnose your issue if you attach your part file.
I don't know why you wish to unbend the part to perform the extrusion on it as it is not required if the extrusion doesn't cross the bend, but anyways, here is how you can do what you require. The flat pattern is concidered the brute of the final result of your part so if you add the extrusion in there, it will obviously not show on the original state.
You can use the flatten feature to flatten the part.
Afterwards, do your extrusion as you wish.
Use the fold feature to fold it back to it's finished state.
2016 SOLIDWORKS Help - Flattening Sheet Metal Bodies
Know this tough, this isn't standard workflow. Think of it this way, would the guy on the shop floor fold the part, unfold it, cut the hole and refold it or would he get it cut correctly and then folded? You're stuck in the 2D/shop line of thinking.
Opportunity for me to learn something. Why is it not necessary to unfold part to put in hole across bend?
Well, across a bend it is indeed necessary I just skimmed over his first pictures and didn't see the bend line.
If the hole was positioned anywhere else that is flat and doesn't touch the bend then it wouldn't need unbending but in this case it is required in order to get the desired result, which would be a sort of clearance hole.
And here I was hoping that SolidWorks added some type of "normal" hole cut feature that I had not heard about to sheet metal so the unfold feature would be unnecessary .
Let's not kid ourselves

Something like this?
Yes something like that. However, if they do it the way I imagine SolidWorks would, it probably creates a hidden unfold/fold feature so there is no advantage.
