Yes, I have had several hotshot young bosses - what upsets them most is when I show them up. It is okay to disagree with your boss, UNLESS it turns out your boss is wrong, and you are right. I have fixed machines that engineers and technicians with several years more education, several years more experience, and several years more seniority couldn't fix. But now I am being immodest.
Sure, the world could survive without my skills. Are you suggesting that the world could not survive without you ? One day, many years from now, you will look back on this and wonder why it seemed so important at the time.
I have found that getting angry and tense doesn't help, so now I just try to find the humor in watching young hotshots flail and founder. And if they do eventually ask for my help, I do try to help them.
Angry much? Fyi i know how to use a slide ruler, i am a collector of slide rulers too. I also know how to add even though i use a debit card. I have a degree in math as well. Also because i have a degree in math and my extensive knowledge in analysis and geometry i have a perfect understanding of 3D. I am also working on a masters in computer science. Now stop being cranky because the world can survive without your skills. And a friendly advice. When you get that hot shot young boss (you will at some point in your career) dont talk to him with this attitude.
I guess you are also glad you never had to learn how to use a slide rule - that was my first 'calculator', and the batteries never died at a critical time. The operator had to know where to put the decimal point. And the first electronic calculators (red LED's) were 'slide-rule calculators', before the time of digital calculators.
CAD helps a draughtsman draw better. But if you don't know how to draw by hand, you can't draw in CAD. I had CAD-CAM operators complain that they couldn't create a certain profile in CAD. But they also couldn't explain what they were trying to do. After sketching from their description, usually by the 3rd revision I had deciphered what they wanted to do. Then I could explain the steps to re-create the profile in CAD.
But then I also feel sorry for the cashiers that have to rely on the cash register to calculate change. If they punch in too quickly and it says $0.18 change, they have no idea that the 7 cents I am offering is to make up to a quarter (25 cents). (I expect you just use your debit card.)
The most important tool for any Engineer, is a brain that works. That is what actually makes your tools, whichever are your favorites, useful.
is all an engineer needs. Drawing and drafting in college is generally last grasp to resist change from older engineers that feel cheated that they had to go through the pains of learning how to draw and the younger generation does not. Same thing happened with calculators and now and it's happening again with the internet.
I took drafting in college. I was never very good, but there are skills there that are necessary to have in your career, and I see it as a critical step to communicating. I'm an EE, but I've often been responsible for the "whole box". Being able to draw (even incompetently) allows you to better "see" things yourself, and communicate them across job boundaries.
Just as children must learn math BEFORE they start using calculators, Engineers should learn to draw and communicate effectively. After all, Engineering is both creation and communication; what's that if not ART?
Reminds me of a good Engineering book: A Canticle for Leibowitz
Both my parents are Electro mechanical tech's with Vocational high school degrees. Both of them are capable of drawing better than the paid drafters in our company. They tried and tried to teach me how to draw. It never clicked. I can draw stick people, my circles look like ellipses, and lets just say that I prefer hyperbolic geometry since I cannot draw straight lines. I am grateful that drafting is not required any more. That would have been a road block for me. I enjoy looking at the work but it's a dying art. Soon enough the only place to hold any hand drafted plans will be museums.
I'm the same, ChasChas. I could draw a plan view or elevation reasonably well, but was incapable of doing an oblique view of even the simplest objects. After awhile, my employers understood this and tended to put me in front of a computer, where I could do less damage.
Excellent point, vimulkumarp, and I'm glad somebody said it. I've read "To Engineer Is Human" twice and have quoted it on this website more than once. Professor Petroski has a rare quality among university professors these days -- he's a master of communication who can speak equally well to experts and to the man on the street.
CAD is a tool for a draughtsman. If you don't know how to properly use CAD, the result is garbage, not a drawing. One basic that is not understood is that a CAD drawing is drawn full size, but is scaled to fit the paper it will be printed on. The first job that I had using AutoCAD Release 9 (I learned on Release 10), had drawings done by a hacker - every mistake that we had been taught to not do, was in that drawing. I learned manual drafting, so I appreciate the accuracy and features of CAD. One of the finer points of manual drafting was knowing how to do a true size projection.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
