which one do you prefer and why!? if you still want to answer this question but you dont have knowlage of cad or havent used it then think of the question this way: hand writing vs typing!? (10p's to appropriate, detailed answer)Www@QuestionHome@Com Best Answer - Chosen by Asker: Ultimately it depends on what you need to design!. Are you drawing an injection molded hand drill assembly, or a wood bench just for sitting on the back porch of your house!? 1!. CAD & Digital vector design offers a lot more flexibility!. Data can be sent directly to other digital applications, like a CNC cutter for a car decal or a stress testing program like FEA!. 3D models go further in offering virtual computer simulation of moving parts!. If errors in the design are found, a small change is made and the test is run again!. 2!. CAD is cheaper and more environmentally friendly!. Rather than wasting reams of paper drafting modifications, everything is stored on a computer!. True, it consumes some electric, but hand drafting consumes hours more human power, not to mention the weight and cost of large boards, paper, templates and a drafting machine!. 3!. CAD is more secure!. Data can be encrypted!. Paper drawings aren't (normally)!. 4!. CAD is far more reliable and accurate!. Board draftsmen often derive measurements by hand!. CAD dimensions are calculated electronically to a desired level of accuracy!. 5!. CAD is faster!. For example, template objects still need to be traced by hand on the board, but they can be inserted scaled and positioned by just a few mouse clicks in CAD!. But CAD really shines when it comes time to make modifications of an existing drawing!. Anyone who says the board is faster just never bothered to learn CAD!. 6!. It makes team development easier!. The same drawing can be referenced and changed by an entire department!. 7!. CAD data doesn't degrade, fade, burn or get yellow!. Well not normally!. Contrary to rumors, there are CAD programs that run on any modern computer, even the low end Celeron chip will run KeyCAD or some simple app!. also, there are many free CAD programs for personal use, like progeCAD Smart! That all being said, hand drawing will always have its place!. I find it often easier to think up the original concept on the board just drawing a few lines until I am happy with the idea hidden in the chicken scratch that only I can read, then I move to to CAD for concept development, finalization, printing, collaboration and any CAM prototyping that needs done!. In reality, this is probably how most engineers work today!.Www@QuestionHome@Com as a fashion student - i prefer CAD!. Any assignment i have to hand in will always be in cad, it quicker and more professional looking!. However at home i don't have access to any cad facilities because its so expensive!. and its not just the software - i think you need a pretty powerful computer to run it quickly enough!. Saying that though 'traditional equipment' is pretty expensive too, but at least you can build it up slowly!. So if i'm just at home and i have an idea i just draw it but it's easier to develop designs using cad!. Some people think that because its computer generated its less worthy of merit but it's still an artist creating that image!.Www@QuestionHome@Com Almost always, hand drawing is better than cad because of the speed, ease of manipulation, immediacy of image, and expressive nature!. Cad can be better for some detailed technical work and engineering drawing, but even then it's relatively slow!. For expressive drawing digital images, get a graphics pad, ie Wacom, etc!. For expressive drawings to hang on a wall, get a pencil!.Www@QuestionHome@Com |
