Does anyone know any good guides / reference books etc for creating proper drawings?
Ideally something that covers general engineering and structural drawings (not architectural) and thats correct to the current EN and ISO
standards.
I learnt do do them by hand to BS308 back in the dark ages (so I'm a little out of date), however I'm finding most younger folk can use the
CAD software fine, but don't have a clue when it comes to making a good drawing
Cheers

^^^ I'm sure that's the case, but somehow I've got to educate them - if possible without having to go back to the out of date standards.....
BS308 was replaced with BS8888 which most places (try) to work to now.
What about this:
http://www.amazon.co.uk/Manual-Engineering-Drawing-Specification-Documentation/dp/0080966527/ref=sr_1_1?s=books&ie=UTF8&qid=1457003707&sr=
1-1&keywords=bs8888
I was taught to draw as an apprentice at Rolls Royce with a pencil and rule... (never a ruler!) Just copying out existing drawings the company uses is
probably the best way to learn how its done... Every company I have worked for has wanted their drawings done slightly differently... all are valid
methods but senior engineers seem to want things done "their" way...
Start with copying drawings and then give the youths a simple (ish) object and get them to draw it with correct dimensions..... and correct
tollerances on the dimensions if your feeling cruel!
To a point its just practice and being able to think in 3D. So many students draw amazing stuff in CAD which could never be made in a million
years.... You need to understand how something is going to be made to be able to draw it properly.

Grrr... you don't draw with a rule, you measure with it.
People who pick up my scale rule and use it to draw straight lines against scratch their nails down the very blackboard of my soul!![]()
^^^ I guess that makes me the awkward engineer then
One problem I'm having is that some of them are coming in as "experienced" draftsmen who apparently know it all...
So a handy reference book would be nice when trying to explain why it needs re-drawn
(not saying I always follow the standards perfectly, but there is a big difference between an easy to read, nicely laid out drawing and one with all
the views crammed in on some weird scale and random details / sections all over the place, often missing the important dimensions or notes
)
BS8888 is ok, but something simpler with less reference to other standards would be nice, the old BS 308 had a student edition that was quite good but
its never been replaced as far as I know

That's harsh!
I think I'd have kept him on just for entertainment value!![]()

As a "new" engineer (been an engineer for 4 years now) I found that Uni completely failed to prepare me to create drawings, especially regarding GD&T. I'd echo that giving people drawings to look at is a good start, but practice is the best way and it's important to explain why something is that way. I did the IMechE GD&T course just before Christmas and that helped an immense amount.
I was lucky enough to have a copy of BS8888 at my old work place.
This only states how you annotate a drawing. Not why when or where. This is an art that comes with practice and experience of working with a machine
shop or fabricators. Some of the dimensions i add to my drawing are for manufacturing, some for QA.
Slash cut across tubes is one i did today. Noting that its a cut in a certain place at an angle is one thing, QA that it provides the internal tube
dimensions at its face is something completely different.
I started at 16 years old in 1989, at an old engineering company. I spent the first 6 months re-drawing & converting all the drawings into metric,
that was enough to teach me how things were drawn. As a side bonus, it also taught me how to convert between metric & imperial in my head which
has come in useful over the years.
Ive recently started using autocad (about 12 months now) after 15+ years out of design/engineering & I am really enjoying it.
I would still prefer to be physiacally drawing it all but autocad makes repetitive items a doddle :-)
I teach Engineering drawin for technicians and I also teach Autocad,
have a look at the btec specification for the units..
First thin I teach the kids to do is sketch a cube in Isometric, oblique and third angle projection..
I Know..draw a box..
you would be amazed at the amount who take a week or 2 to be able too.
Then I move onto measurements, and the drawing standards that apply to them.

^^ you'd probably kill me for some of my bad habits...
Is it just me that thinks alot of the new timesaving features in autocad actual slow it down ?
I've spent ages customizing 2014LT to make it as near to 2000 as I can make it (I hate dynamic input with a passion)
