I wish to know whether isometric view is a must for a drawing. Because this drawing is without isometric view.
Some company standards may require one, but otherwise no, they aren't necessary in every situation. I've created many drawings without an isometric view. I typically only include them if I feel it makes the drawing easier to understand (or I have room on the sheet and need something to fill it).
For this drawing, it's not a must. You could add one at a smaller scale (it doesn't have to be at same scale as the rest of the drawing) in the lower left corner.
For the few seconds it take, an ISO view make it easier to understand the drawing.
Even a small one.
If a third person happened to look at the drawing, will not it be difficult to imagine the part?
Standard Practices - Isometric View
Personally, since an isometric view is easy to create, I always add it, even if it in a smaller scale.
What is meant by easy to create? once you complete all the part only you can get an isometric view.

When I started out on the shop floor back in the last century - all drawings were done on drawing board and no isometric views.
Then the technology transitioned to AutoCAD, but still no (or rarely) isometric views.
It wasn't until 3D CAD modeling took hold that it became trivially easy and common to create isometric views.
It was easy since Mechanical Desktop.
Now it is easy because it is a virtual Mechanical Desktop.
Mechanical Desktop was AutoCAD.
Mechanical Desktop was before Inventor.
Everything on a drawing must convey, at least in part, what's required to understand and correctly purchase, fabricate and inspect the part.
An isometric view is usually added to convey some "3D-ness" to help clarify contours, but I don't believe there's a requirement to have one on every drawing.
So, my guess the answer is, "Does it add value?"
This is the part of the drawing.

Exactly. I've seen people add isometric views to drawings to the detriment of the other views. What value comes from an isometric view of a rectangular bar with a hole drilled through it?
I don't think there is such a standard which iso view must be attached; however, it'd help the readers, machine shop or vendor, to view the dwg better
Value and cost.
How much does it cost to add an ISO view?
For not much, it can avoid mistakes that will cost a lot more.
Probably in 1000 time the cost of an ISO view.

I mean that with just two clicks of a button I can have an isometric view on the drawing. Easy to create.
Yes it is true small mistake may cause million of dollars lost to company. In my view it is necessary to add isometric view to avoid any mishap.
Although it starts life as a section view, an isometric section view can benefit from being a section and an iso:
I assume you are saying about placing isometric view in the drawing sheet.
Adding ISO cost so little.
Adding a company procedure on when an ISO is required possibly cost way more.
All it took is one stupid to wipe out whatever "saving" there was by not adding ISO view.
I'm the one adding ISO view on rectangle without hole.

AutoCAD on steroids.
Then we discovered the negative effects of attempting to enhance performance through artificial means.
As others have said, it is not necessary. It is easy to add though and in my opinion, the only time an isometric view is needed is when it adds more definition to manufacturing the part that the standard projected views don't give you.

Yes this is what I am saying.
In my opinion, this drawing would benefit from an isometric view.
Also, the drawing is very busy and poorly arranged to begin with.

Hiding the tangent edges, or making them a lighter font, would have been a good start. I generally don't show tangent edges, but when I do they're gray, phantom, and the thinnest line.
