Engineering sketches, please help!?
This is for coarsework, i am not intending to produce a drawing myself, i just need to show that i have understood what a pictorial drawing is and different techniques of creating/showing one. Thank you.
How is engineering drawing useful for ECE?
I'm doing my final year ECE and honestly speaking engineering drawing is very useful of only one reason and that is"Improve your grades" dat too with a '*' .Now the terms and conditions~ you must be good at drawing.~you have all the shades of pencils.~you should fix your drafter (it doesn't matter if you use it or not:P).~you must be lucky enough to get something easy to draw on the final exam day :POther than that i have not used it anywhere else.!
What is the difference between sketching and engineering drawing?
In the engineering context, a sketch is usually quickly drawn by hand on paper, intended to show the approximate shape or appearance of a part, machine or structure. It could show a view perpendicular to the top, front or side, or a view from any angle. It might include some dimensions, but it’s not intended to be precise.An engineering drawing is intended to be a precise representation, and is drawn at a specific scale with dimensions located to show the exact distance between points. It can show sections cut through a part, assembly or structure, or complex assemblies with many parts, and even assemblies with parts separated, called an exploded view.Back in the old days, all engineering drawings were laboriously created by hand on large sheets of paper taped onto drafting boards. These days, the engineer uses a computer to create 3D models of each part and then assembles them on the screen. The computer can create all the required engineering drawings, including dimensions, sections and exploded assemblies.Search Google images for napkin sketch and engineering drawing and you’ll see the difference.
What is the importance of sketching in engineering?
My college curriculum many years ago called for drafting so that we could both generate and read drawings. I often wondered where the input for the formal drawing came from. Interestingly, I have learned much since college in my attempts to communicate with the Engineering community.Sketches do many things. Certainly, they communicate concepts and to help develop an idea before the engineer starts the formal process of product specification. However, I have often thought that the usefulness of a sketch was more than just developing an idea or communicating a concept.I think there are several uses to engineering sketches. One is to develop ideas that would not be contained in a formal drawing; the engineer wishes to relate several aspects of the product in a number of ways (kind of a what-if analysis); resolving perceptual differences, especially in collaborative work; and even to transition between visual imagery and textual specification. The term we applied to the drawings was “engineering rendering.” The job of the production specialist was to transform the product from engineering rendering to product realization.
How important is sketching and drawing for mechanical engineers?
Sketching and drawing are really important if you want to be a design engineer.As far as sketching and drawing is concerned, it is carried out in special design softwares like SOLIDWORKS, CATIA, AUTO CAD, CREO etcAt the start of your career as a design engineer you will get the post of Draftsman or Drafting engineer .Initially, atleast 2 years you will be given drafting and detailing jobs. At max you will be assigned the tasks of part modelling but no assembly or simulation job will be provided to you.So if you are really good at your Drafting and Detailing you will soon get promotion.Also if you are a master in drafting and detailing. Then your concepts in other tasks like solid modelling, surface modelling will be automatically strengthened.Hope it helps !!
Do you need to be good in drawing to be an engineer?
If my history is any example, the answer is an emphatic no. I took one engineering drawing class and my drawings were always the worst, most errors. I was weak at recognizing and visualizing three dimensional objects based on two dimensional drawings but I could do it. If you have need to do that, as in typical mechanical engineering or civil engineering then that need exists. But drawing with CAD tools, not as necessary. There are lots of designers who can do that, take simpler drawings and produce designs that can actually be built.So, I would say no, you don’t need to be good. It is useful but I doubt you would be asked to show a skill in that area in order to get a job. You might, but I doubt it.
Why do designers choose tonal shading to do on their sketches?
I am reading your question as to mean, "Why do designers chose to shade an engineering drawing?" The answer is that it is often NOT an engineer that looks at a technical drawing. An engineer, or technician can look at a blueprint and accurately visualize the object drawn. Not everyone can do that. For some, a more "realistic" rendition helps, say, a lender, or investor see what his money will produce. Even a small bit of shading will help such people "see"the object as it appears in a spatial environment.
Why is technical drawing important in engineering?
Drawings are the fundamental way of communication in engineering. It has developed over many years to physically describe their work, and you must be able to both read and write it to work in engineering design. Drawings show the shape, details and all the dimensions of a part or assembly. Good knowledge of CAD and engineering drawing is often the first thing an employer checks before making a job offer. To learn it, a good teacher helps, but there are many books and tutorials on the internet. Start with the basic principles and build up to more complex drawings. Even if you make only 3D models on the computer and it makes the 2D drawings, you still need to know the language of views, dimensioning, lineweights, sections, detail views and more.Starting with drawing on paper can help, and hand sketching is always a valuable skill in engineering. A good way to learn is to start with 3D modeling in CAD, and then you can quickly create the 2D views according to the rules and examples in books. When you can see the shape of a part in 3D it makes it easy to visualize the 2D views. Both are essential to mechanical engineering. Free versions of popular CAD applications are available for students, and there’s lots of tutorials on the internet. Once you build up some skill, you’ll be way ahead of those who don’t have it.
Do mechanical engineers work with their hands?
I want a job working with my hands, building engines, something like that. I read mechanical engineers do mostly sketches of things, which is not what I would want to do. If they do not, what is an engineering job where I would work with my hands? Also, I speak Spanish and English, should I learn another language, and if so, which one?
Should engineering drawing be taught to every engineering student?
Engineering drawing in the “old days”, pre-CAD put a lot of emphasis on the skills of neat hand lettering, line weights, manipulating pencils and triangles and compasses and templates, etc. Those aren’t really useful skills any more, though hand sketching still has its place. But the other values of engineering drawing include learning / understanding the presentation of data, converting the 2D view to the 3D, and learning how to read drawings and what information has to be presented.-Where are the dimensions or components and how are they called out?-How are tolerances presented?-What are the common symbols and abbreviations in your specific engineering field? And so on.In addition, not in all industries are all of the past product information data in modern CAD format. Sometimes one has to look at previous (even paper!) drawings to gain information about past practices, or to reverse engineer something. Engineering drawings have a language or at least a dialect & jargon of their own. (The term Short-hand is now an archaic but applicable term as well.)So in my opinion, yes some form of drawing should, even must be taught though not necessarily by “drafting”.
