The thrust of this one is less of a 'how-to' and more of a 'how can I police
myself and use CAD without having it influence my design'. I was nervous
about it, but I got the reviews back from the session evaluation forms and
it looks like the point got communicated and was appreciated.
I have interacted with Industrial Designers who would not allow their
'vision' or 'creativity' to be compromised by manufacturing constraints...
"I don't see why we can't get away with an undercut here"."well, I guess you
have to redesign the circuit board to run cooler'."I guess you'll just have
to pull zero draft there".and the perennial favorite: "how about a
collapsing core...." These are the guys who make it hard to work in my
field because, after dealing with memorable prima-donnas, folks in industry
assume that all Industrial Designers are like that.
What is really ironic is that, though these Industrial Designers will not
compromise their 'vision' because of manufacturing constraints, they will
change direction on their designs if they can't figure out how to model the
shape in CAD.
Why does this bulge out here? 'Oh, I just couldn't model the leaner shape
without problems so this was the best I could get"
Why does it get thin and elongated? -"oh that is just what happens when you
flex a part."
That is f***ed up.
They won't change for constraints of the real world, but they cave-in to
constraints of the virtual one. The more I think about it, the more I hate
them for it.
I see it all the time - CAD-centric design is compromising design - or more
accurately, CAD-'feature'-centric design. I try to show that
'product-centric' design, literally forgetting the features while working
through how to construct your product, actually makes the modeling go more
After all, product are what pays eveyone's salaries. A product does not
care how it was modeled, nor does it care about the features that were used
to model it.
And that is the core of this session - not allowing CAD to do any designing
for you. You are smart, CAD is stupid, so lets let the smart party get back
