| 392442 | 2006-01-23 10:12:00 | actually, how much more complicated can CAD drawings be? i guess that what I really want to know... thanks :) |

| 392443 | 2006-01-23 23:44:00 | Things get complex when you build things up. Each part is generally simple. Here's a couple I worked on. The first one would take a couple of hours now that I know how lofts work. The second is a pretty standard assignment from uni. img27.imageshack.us (http://imageshack.us) img68.imageshack.us (http://imageshack.us) If you want to check out some really good stuff look at 3D Content Central (http://www.3dcontentcentral.com). It's full of free models. eDrawings is a good free program to look at SolidWorks models. |

| 392444 | 2006-01-24 03:15:00 | thanks for the reply, 3D looks quite complicated huh :S Well, I did get taught about 3Dmax at uni this yr but it wasn't very successful as there were too few tutors and most of them couldnt explain hell of alot -_-...but I do have it at home to play around with if I am really bored...lately I've been thinking about getting a job as a junior draughtsperson, but most of them required alot of expereince, so I think I sould probabaly boost up my drafting skills before I try to apply, does anyone know how good you have to be at CAD to be a draughtsperson? Dad says all you have to know is how to draw and edit, but i think he's lying -_-... | mini_magget03 (418) | ||
| 392445 | 2006-01-24 04:32:00 | Been watching this thread with interest, so here's some comments based on years of industrial R&D, manufacture, design, in charge of drawing offices, science &c . Remember CAD, and by that I will say Computer Aided Drawing (Computer Aided Design is something quite different believe it or not), is just a tool to speed up and extend manual drawing methods . The end result of producing technical/engineering drawings is to make something from those drawings, whether it be a house, a power station steam turbine generator, automotive parts, pipe work layouts, printed circuit boards, a machine part, etc etc . The field is infinitely vast . You wouldn't believe the number of young drawing office trainees that I've come across that have (beautifully) drawn up unmakeable parts, ( . imagef1 . net . nz/files/staircase . jpg" target="_blank">www . imagef1 . net . nz :) ) or drawn up parts without any idea of the manufacturing process, materials, limits and fits, tolerancing etc . Producing 3D modelling may be ok for learning some of the CAD skills, visualisation, ensuring parts fit etc, and could be useful later on if carrying out FEM, CFD or other computer aided design methods . I have reservations and doubts about training to be a draughtsman without a sound practical background first of all . In the days when there were career structures and apprenticeships, it was not uncommon for ex-apprentices to go into the drawing office where after having had 5 years hands on previous experience ,they could be pretty good design/draughtsmen . The line between design and draughting is vague . It depends on the level and sophistication of design . For instance if you are going to design a computer fan, I'd expect some knowledge of aerodynamic blade design and maths . If it was a really sophisticated fan, say a circulator for a gas cooled nuclear reactor then these days interactive computer fluid dynamic techniques combined with FEM stress analysis, combined with fluid bearing analysis may all be required to arrive at an optimum design . I'd say being good at CAD is secondary to being good at practical design/drawing . After all, programs like Autocad are just tools as I've already said, there is nothing magic in them per se . Like any computer, rubbish in = rubbish out :) Autocad can be learned on the job by doing it . Oh, and incidently my Autocad experience didn't get past version 9 on 386 machines running DOS . :thumbs: Your Dad is right, as all dads are by definition ! |

| 392446 | 2006-01-24 05:18:00 | That's one view of the Penrose staircase, Terry, but for a better "design" using it M C Esher (www.worldofescher.com/gallery/AscendingDescendingLg.html) did this. I think he used a pencil, not a CAD programme. ;) | Graham L (2) | ||
| 392447 | 2006-01-24 20:35:00 | ohhhhhhhh ic, so I should not only practice more on my CAD skills, but also focus more on my background knowledge in architectural sturcure and constructions in orer to aid my drawings since it is the content that is more important, not how you do it....that sounds like a good idea! After all, I'm sure I am missing out on some crucial infos at uni as a first year arch student. mmm, all these pc talks are making me real excited about getting back into my CAD and arch work :) thanks all! | mini_magget03 (418) | ||
| 392448 | 2006-01-25 06:56:00 | The guy who co-authored AutoCAD is a Swiss called John Walker. He has a really interesting web site here: http://www.fourmilab.ch/ There is a nice screen saver that is a view of Earth illiminated by the Sun, viewed from the Moon. He's done all sorts of things and has a view on everything. What a character!! |
