# Manual Drawing / Sketching

 P: 79 Is manual drawing with pencil and paper a good quality an engineer should have at his power? I'm still an undergrad and I understand all drawing is done with CAD packages, but I still enjoy drawing free hand before I put it onto software (I guess because I'm not so good at using CAD) Or am I wasting my time drawing back to the basics?
 P: 35 You are not wasting your time - nothing is faster for presenting or explaining an initial idea than pen and paper.
 Sci Advisor PF Gold P: 2,793 Good skill, if you ever need anything knocking up then you won't have the time or equipment to do it on CAD. 'Proper' technical drawing also shows you how to actually detail drawings properly!
 Sci Advisor HW Helper PF Gold P: 2,906 Manual Drawing / Sketching I put all my pencil and ink tools in a box years ago. I even have an electric eraser! They'll get donated to a museum in a hundred years by my grand daughter... I only use CAD now, but it's a neat thing to learn I think. Learning 3D packages would be more marketable though.
 P: 563 I'm old school, learned drafting a long time ago, well before CAD but I took an evening course in CAD as soon as I knew it was around (AutoCAD 10). Loved it and have been using CAD ever since. Knowing how to draw and sketch is very useful, as is knowing how to use a lathe and a mill (I'm also a machinist). I feel that it really speeds up my CAD drawing. Once the serious drafting begins though, the paper and pencil get left behind very quickly! You'll soon learn a bunch of shortcuts that help you draw quickly with CAD, just keep practicing and trying out the tools.
 P: 79 Thanks for the replies, I only ask as its something I've always enjoyed before I begin to use CAD systems. I just wondered if it would be a good skill to have in future in the real working world
 P: 25 Drafting, in the traditional way, isn't really that useful. Letter spacing, height, blah blah blah, I would punt on the majority of the nitpicky drafting skills which were required of ages gone past. HOWEVER, good sketching and dimensioning are really powerful. They are quick, they don't require a drafter to muck about, whine, question, and finally deliver a drawing. You can get a good sketch to the shop and be off and running way before a cad program. In practice, i find that the above situation really plays out on standalong parts or simple to medium complexity fixturing. Try out some of the learn-to-draw stuff for anime machines and guns. Drawing mechanical things is very impressive and can easily be the difference that gets you that job. And learn the dimensioning symbols and such. Know them cold. my.02$P: 79  Quote by nathanlee52 Drafting, in the traditional way, isn't really that useful.

Thats for your input, where could I find these "learn-to-draw" exercises you are talking about? Also do you know of any good links for dimensioning symbols? I can only find basics with little or not explanation.

Also another question, 'Professional Engineering Drawings' can these be done by hand or does industry / universities purely expect these to be done by CAD packages?

I think that manual sketch is a good one. But you should try to use the CAD so that your drawings will be more efficient and more sophisticated. If you are a future engineering, you should know how to use it. :D
 P: 25 Jones1987, missed your other question, about books for mechanical drawing.. and to that, well, there are many. 1) I would avoid the ancient texts on drawing mechanical things. Purely on the grounds that the presentation is boring. /flame suit activated 2) I would take a look at manga / anime drawing on robots. It's more useful than you think. Trace their art. You'll develop the feel that way. 3) tracing in general is awesome. Trace a cad print of something complicated. Use Rulers. Take your time and have some beers while you do it. I bet you have some fun. Well, not fun like strip calculus, but i'm getting off topic.. 4) Learn isometric DOT graph paper. Go print one off on one of the many sites. Then, find a copier, max it out to WICKED dark. This is now your master. You can put regular copier paper over that and draw. (Vellum works best tho). Now, you have regular plotting elements and can incorporate perspective really simply. The best part is you peel it off your Master and voila, no lines other than your drawing. http://illuminations.nctm.org/LessonDetail.aspx?ID=L607 See how easy it'd be to slap on a few dimensions to that scrabble like looking thing. And way more flashy than orthoganol representation. Don't go for flash over function though., unless it's supposed to be art and not an engineering drawing. Maybe this gives you some ideas.
