<p>There is less than a 1/4 in between the bumper and the grill. If
there was another 1/4in, I could slip a 1/4in universal socket
with a long extension and get the grill out. Part of this is due
to the cad programs. The other part is very few engineers have
any clue as to how to repair the vehicle they are designing... I
guess it could be attributed to the absence of high school shop
classes........ When I get the barn cleaned out and my 4post lift
in there, I will get it raised up and change the lights.<br>

<div>You might be right for autos. My experience was Paccar (KW,

Boeing also used ProE. Things may have changed the last few

<div dir="ltr">Interesting comments on screen
sizes James. I've got a dual monitor setup,
27" in front of me and 21" just to the right.
When doing CAD work, it's mostly done on the
main screen, with the smaller one containing
notes, word processor, internet browser,
calculator, useful tools along those lines.
But to comment on scale: A practical problem
I run into is with small parts. It is a basic
functionality of CAD to zoom, pan, and rotate
the part or assembly on screen. You can take
a tiny part and fill the screen with it and
lose appreciation for scale very quickly.

When vehicles were designed on the board,
they drew in 1/2 scale. You could look at a
drawing and relate it to reality. If you
taped a drawing to a wall, you could get a
sense of the vehicle size. If a designer
had a full size or 1/2 size CAD screen,
those inaccessible places would be much more
noticeable. People doing 3D solid modelling
sometimes have multiple screens, one for
each view. It would be difficult to design
anything on a smart phone screen. It is not
much easier on a small monitor. Monitors do
continually get larger, just like TV
screens.<br>
<br>
Some years ago I read some issues of a then
DaimlerChrysler employee newsletter. One
article covered a group that real world
verified that all maintenance operations
could be performed on a new model. If the
maintenance could not be performed, the
group would have to design a specialized
tool or get a tool manufacturer to design
the tool and offer it for sale.<br>
<br>
They did all this after the vehicle had been
designed and production was imminent. I am
guessing that moving heaven and earth would
be easier than getting the product design
changed.<br>
<br>
Toyota which emphasizes production
efficiency not product design may not do it
any differently.<br>

<snap> This is the problem of
designing with AutoCAD and those other
computer drafting programs. The designer has
no idea of the clearance in the finished
product. <snip><br>
