Exactly what you want ?

What I will advice you is to have a look at the drawings of your company as well as from other sources and try to understand them

Get hold of some Engineering drawing book

Your organisation may already have some system of the drawings practices (We call it DOP- Drawing Office Practce) , do not try to go tangentially away from it, you may have problems with your production line, and if they fail to understand then everything will be a mess.

Do not be stingy with sections, views etc. They make the life a little bit easier for the line staff.

Make always the drawing to scale and then scale the frame to fit (and not the drawing descale to fit the frame- this helps in future when you check dimensions - assuming you are drawing in CAD)

Though you must use views and sections liberally, but not too much, since the user have to study each of them and understand. An unnecessary one means more strain on him as well as more chance of mis-understanding.

The dimensions should not be repeated in views (say a hole is visiblein 2 views, do not write dimension in both) this helps in future revisions. I have seen a great many times when drawings are modified, the draughtsman has forgotten to change the dimension in one view, whereas he has done in another.

Keep related dimension together. Even rotate, position your sections and views to have it so.

Most important: remember the drawing is for the user. make his life simpler. So many drawings I have seen are technically correct, but just a bit difficult for user to understand and thereby commit mistakes.
