Question about drawing views
Question about drawing views
(OP)
I received a drawing of a gear from a customer. On the left side he has drawin a front view of a gear. He has taken a section at 15 deg to horizontal and shown that in the middle of sheet. And on the right side he has drawn the back view of the left hand view. He has not named it as such on the drawing. I would like to know if this is a standard practice or not.

AT the extreme left, there is the front view of disc
( essentially a circle showing different holes and so on)and a section line at 15 deg to horizontal (section AA). Next to this is a sectional view AA , which is essentially a rectangle). Next to this sectional view , on the extreme right side of the drawing , is the view of the gear ( essentially a circle). This view at Right side is drawn as if we are looking at view at the left side from back side.
So in my opinion it is not a first angle and Third angle projection. It is probably an eror or soem drawing method which I am not aware of.

It would appear that your drawing was drawn by a proctological drafter (a quite common specialty which requires years of ignoring instruction and standards).

I agree with you.
