Welcome to this issue of 2PLM, an e-zine distributed every two weeks on a free subscription basis. This week's article, The Ascent of 3D is from regular contributor Mike Bryan. Mike's previous article, 'In Search of the True Product Data' can be read in the February 25, 2002 issue.
* Various Announcements *
First though, a few announcements.
The name of this e-zine has changed from 2PDM to PLM.
Note that the 'sender' field for the e-mail to which the e-zine is attached will be changed from 2PDM e-zine to John Stark Associates.
In the June 18, 2001 issue we mentioned that the PLM market had been estimated at $18 billion in 2001, but were unaware of the definition of PLM. Since then we have provided our own definition. We have also structured the PLM software and services market into the following main categories:
* The Ascent of 3D *
A long time ago in the early 1980s I wrote an article for a CADCAM magazine entitled 'The Unacceptable Face of CADCAM' and I was trying to make what I thought was a valid point.
I started my Drawing Office career in 1959 at the age of 23 on the drawing board as a junior draughtsman and had to wait until I was 30 to become a senior draughtsman and get the full rate of pay. It was very easy to distinguish between the work of juniors and seniors by the presentation of the drawing. The work of the seniors was confident and cleanly drawn with bold dimensioning. The work of juniors tended to show much evidence of erasing with hesitant and spidery dimensioning. Obviously when drawings were checked the very presentation of the drawing identified those that required close scrutiny.
The introduction of CAD systems into drawing offices changed all that. Now all drawings had a common, machine-generated, bland appearance. The 'presentation signature' of the senior draughtsman was lost and with it the individuality and character of the drawing. This, I believed, was the downside of CAD.
Furthermore, management (in its wisdom) tended to look upon these CAD-produced drawings as being as flawless as their presentation and failed to realize that the CAD system was just a tool and only as good as the draughtsman using it. It's similar to the problem with electronic calculators. Many people who use them get this seemingly highly accurate answer and accept it without question because they haven't bothered to work out a ballpark figure. I grew up using a slide-rule where you needed to estimate an approximate answer in order to place the decimal point. I know - I sound like a Luddite but I shudder when I read about things being 'computer-designed'.
From the late 1970s we were using CAD systems for 2D design and detailing but the drawings were still being checked from the hardcopy. But now, because of their anonymous appearance, it was not possible to determine immediately the innate quality of the work. What was worse, however, was that management now thought that CAD systems had de-skilled the job and that pretty much anyone could be put in front of a CAD system, albeit with the requisite training, and produce top quality work.
The plain fact was, and is, though, that an incompetent using a powerful CAD system can churn out rubbish at several times the rate he could on the drawing board. The other main problem was that the 'Engineering Drawing' culture was so entrenched that it took a long time to replace it with the 'CAD model' culture. Even now, to some companies, the hard copy bearing all the necessary signatures is still the master document, notwithstanding the fact that it cannot be used directly for analysis or manufacture and therefore has little legitimacy.
And this highlights the most serious problem - that it is generally only the printed representation of the CAD model that is checked, because that is tradition, instead of the CAD model which is what will be distributed throughout the CPC/PLM environment for manufacture, analysis and subsequent measurement. It is vitally important that the CAD model itself is checked, particularly the geometric accuracy, but before this can be done it is necessary to have company CAD standards in place.
For instance, what are the rules governing the use of colour? When creating geometry do we construct to the mean of the tolerance or to maximum metal conditions? How should layers be used, etc.? Checking isn't too difficult with 2D models and in fact can be automated. But if we don't or can't do it for 2D, should we be attempting to use 3D CAD? And this is not withstanding the obvious drawbacks of 2D. Anyone who has designed a casting on the drawing board will know the frustration of trying to visualize every single feature and blend to make sure that it can be cast and that there are no dangerously thin sections. In the end you hoped that if there was a problem then the pattern maker would find it.
The use of 3D is truly advantageous but its use multiplies the problems of drawing/model checking. Establishing a standard for 2D models/drawings is one thing, and I suspect this is not widely done, but producing a standard for 3D model construction is an order of magnitude more difficult.
Yet we are more adventurous with 3D because we can produce more complex shapes. I know from personal experience that when aerofoil sections were drawn for very simple shaped blades, they were checked very carefully. When 3D surface design enabled us to produce very complex shapes with many different aerofoil sections blended together, no checking was attempted because it was deemed to be too difficult. What we had was what we had.
In these days of DASAMASA (Design Anywhere, Sell Anywhere, Manufacture Anywhere, Support Anywhere), I wonder if Anyone Anywhere really knows what we have. Perhaps this is one of the reasons there are still so many product recalls.
I hope to pursue this theme in another article, editor willing.
