My native language is not English and I do now know anything about any other drawings standards. Is it possible to extract a small piece, a section of a drawing and place it at the side like in the picture I am enclosing?

I am looking to do something like the arrows point at, extract a section represented by the letter "E".

No, I will not supply a drawing. This is what I provide and if the moderator/s think it is no good then I accept that.
