I cannot use a sliderule. I cannot draw a print by hand - surely not a 3d presentation. I understand blueprints were blue. I cannot optimize without a program. Lost without FEA, math by hand? Come on now! etc. etc.
Without the computer, software, internet, etc., this versatile engineer is obsolete.
I have used a slide rule for design work, and still can, except that the calculator does provide more exact figures, which are critical for verifying fits and clearances. I do sketch freehand but my sketches are ugly, but that is OK, the drafters assure me. Job security for them. Modeling is done using the cad program because of the tight clearances. The rest of the modelling, and the visualization, is ALL done inn my head. Good 3D rendering and very high resolution.
So not all engineers are dependant on the tools to make stuff happen. BUT the cad drawings certainly do look nicer. And the CAD system certainly makes it easier to pull off details for manufacturing to make.
FEA is all done by experienced estimates, while for CFD, it is all visualized. Much faster and not as accurate, except for sometimes.
This isn't necessarily a guide, but a record of what I had to do to stay relevant in the ever evolving embedded engineering career world. It's for the generalist, more so. Most jobs I get, the company has only a vague idea of what they need. That need often changes at a drop of a hat, then I have to switch gears.
I sometimes wish I could just sit there and write highly complex Java programs all day. Be the master-level expert at something and go home. Instead I have to design a PCB.. then the enclosure for it.
Here is a breakdown of the programs I use, so you can get to those tutorials! -
Great post Cabe. I remember years ago when I was a senior in Mechanical Engineering, my advisor indicated the half-life of an engineer was about five (5) years. This, of course, was based upon changing technology and not really the digital age. We had not entered that age as yet. I have absolutely no idea as to half-life now but it can't be much more than two or three years IF you wish to keep up. I just took an assignment on developing a vortex tube for a specific application. Had to go back to school on this one. As a consulting engineer, I find that to be the rule and not the exception. One of the very best vehicles for "keeping up" is Design News Daily. I find this web site to be extremely valuable for guys like us. Again, great post.
Half-life isn't an measure anymore (only an award winning video game series). Many adept "engineers" I know do not even have a degree. They instead learn on their own. Like my post shows here, you can learn anything you want, rather quickly too.
The tech is there to hold your hand all the way through.
Relevancy all depends on the engineer's needs and ambitions, these days.
Autodesk, a leader in 3D design solutions, announced earlier this month that it has completed its acquisition of Delcam, a leading supplier of CAD/CAM manufacturing software, in its efforts to expand the company’s manufacturing software capabilities.
Texas Instruments' Webench is vying to win the Golden Mousetrap Award in the Analysis & Calculation Software category, but it is up against some pretty tough competition from Mentor Graphics, COMSOL, and aPriori Inc.
Agilent, solidThinking, and MSC Software are hoping to take the top prize in the CAD/PDM/PLM software category of this year's Golden Mousetrap Awards. Here's what we know about solidThinking's Inspire.
