Fig. 11 No end view is necessary as the part is clearly circular in shape.

at it from several sides and draw what we see. Fig. 12 shows, at the top (a) two sectional views of a compressed air motor, one along the spindle, the other at right angles.

They are accurate and clear, but not so easy to follow as the identical views rearranged as shown below, at (b). These are in projection, on the same centreline; much easier to read and, in fact, to draw.

It is very unfortunate that if you enrol for a drawing class you will almost certainly be introduced to this aspect of drawing via a tedious and rather academic route, dealing with abstruse geometrical shapes which appear to have little relevance to real engineering. Yet it is really quite straightforward.
