Is CAD a graphic art?

NO!... it's a drafting / modeling application.


Rot! CAD: Computor Aided Design; the operative word here being
design.


The operative term is 'Computer Aided'. The 'D' properly stands for
'Drafting'. CAD is an electronic drawing board - it doesn't contain 'design'
tools, it contains 'drafting' tools.


Some design is pure science, some is pure art, most is a bit
of both.


Good design is about finding solutions to address specific problems. Good
drafting is about expressing or describing those solutions with sufficent
competence for them to be implemented.


Show me a good designer and I'll show you an artist.


There are plenty of good designs that are badly drawn - because there are
good designers that can't drive CAD (or draw) to save themselves.

I concur!

Exactly!

Marty... listen to Wally... he knows what he's talking about!

Well, you're both wrong... or maybe it's just that you've been using the
cheap set of AutoCad tools. AutoCad will do a large number of design
calculations including area, volume, centers of mass, and moments of
inertia. It will also extract a bill of materials

Well stated.

And are either too arrogant or too poor to hire a good draftsman.

Oh **** off Doug..... nothing stated was in any way wrong! If you need to
elevate yourself due to some inferiority complex... which seems to be the
case... so be it... but do try to come up with a better methodology than
stating we are wrong and then substantiating what we just said.

Oh, please excuse me. It seemed to me that you were saying that AutoCad
did not include any *design* tools, which is wrong.

Always remember, never forget... some people have inferiority complexes,
others are just plain inferior.

Well Well well... seems you started calling me fool without reading the
thread.... here Doug.. I'll help you out... this is what I wrote :

It's a misnomer..... vector based and you provide the coordinates for it
to

plot.. 2D or 3D. Yes you can design from scratch.... but try and import a
rastar based graphic to incorporate and your **** out of luck. It's utilzed
in engineering.. not graphics

...and Wally's reply is correct as well... :

'Drafting'. CAD is an electronic drawing board - it doesn't contain
'design'

There is nothing false in that statement.... autoCad is a drafting
application

....and some like you suffer both simultaneously.

I guess figuring centers of mass and IMM or IXX is a drafting job. Silly me.

Mooron is such a child that he can't ever, ever admit he's wrong. Maybe
he'll tell us again how he's right and the NIH and NASA are wrong.

What, exactly, is "the cheap set of AutoCad tools"?

moments of inertia.


AutoCAD is a drafting tool - it's used to produce drawings so that people
can make things. It's far too generic to be truly useful as a design tool in
the sense that you're alluding to. Contrast it with the software that's used
to simulate electronic circuits - they are true design tools because they
allow you to test and iterate complex designs to the point where the result
can be manufactured and pretty-much function as intended. You draw a
schematic, and it does output analysis and PCB routing for you.

To acheive the same in AutoCAD requires a far greater degree of effort and
input from the user, and stock AutoCAD just isn't used in that way in any
proliferate sense at all. For AutoCAD to reach similar effectiveness in a
real-world situation, it needs to be enhanced with the various AutoDesk and
3rd-party add-ons that do far more sophisticated calculations and procedures
(ie, vertical enough for their intended purpose).


It will also extract a bill of materials


Generating a BoM has nothing to do with designing something - design is when
you start with the problem and come up with a solution. The BoM comes after
you have the solution designed and want to build it. I've never met anyone
who actually uses AutoCAD's BoM - it's too cumbersome and requires the user
to draw in a specific way that's conducive to making the BoM work. AutoCAD
is a great drafting tool, but it's a **** database and a **** scheduling
tool. By and large, people just don't draw like that, mainly because they
don't have time to - it's less hassle to schedule semi-manually
(spreadsheets and the like), or to generate BoMs from vertical tools
designed for the purpose.

For instance, I could use AutoCAD to find out exactly what size the windows
are in a building, but to get a parts list, those sizes are entered into a
BoM tool provided by the maker of the particular window system - tell it the
size, how many panes, opening lights, etc, and it'll spit out a list of
everything to the last nut and bolt, inlcuding a cutting list to be fed
straight to the saw that chops up the extruded ally profiles that will
become the window frames.

The minimum installed module set that doesn't do any of the fancy math
for design work.

Yep

That depends what what you're designing. Certainly no engineer is going
to sit down in front of AutoCad and whack out the parameters for
whatever he's thinking about. That's a job for pencil & paper at first &
then some specific math-heavy program.

But the bottom line is that AutoCad *does* include the tools to both
ensure that a given design is within design parameters, that it's
physically possible, and tweak it into better shape.

Sure. Did I say that AutoCad was for designing circuits? But it can be
used to design all sorts of other stuff.

That's true, too... and it's a difficult program to work IMHO. Probably
because I'm too old and finicky, and not enough interested to do the
hard work of learning it thoroughly.

For instance, I could use AutoCAD to find out exactly what size the windows
are in a building, but to get a parts list, those sizes are entered into a
BoM tool provided by the maker of the particular window system - tell it the
size, how many panes, opening lights, etc, and it'll spit out a list of

It's AutoCad, not AutoCam or AutoCAE.

I still say that it includes some design tools but I understand your
objections. You get full credit for making much more intelligent &
meaningful contribution to the subject than Mooron.
