Because you had already considered a number of the possible
issue which might come up. I want a garden shed. I'm on my
third or forth iteration of "I could do it this way.,,"
which is a heck of a lot cheaper than "just starting" and
realizing that "I'm not sure what I wanted, but this
isn't it."

"I should have put this over there, oriented that way, then
the other could fit in that space, and I'd have this area
here "clear"."

Some people like to plan and some people like to act.
Only planning, never doing anything, or only doing things on
instinct - those extremes I think are bad, but anything in
between is up for anyone to make up their own mix, and with
time and experience most people seem to land somewhere that
works for them.

And there it is. The people who like to plan, wind up in the
design department, making detailed formal drawings as "needed." Others
are better at visualizing the component elements and can hold all that
in their head and not need any of these new fangled drawings.

How many engineers build what they're designing? Architects? How many
machinists build a part without detailed drawings of what they're
making?

BTW, if you draw a drawing according to formal methods and
with proper tools, does that count as planning or
effectuating? To me it sounds almost like doing stuff which is
what I prefer...

We're back to the questions of "who is this drawing for?" and
"for what purpose is it made?" For example, last night I took the
measurements of a student desk I thought to use for something else.
First question "Will it fit the space?" after that came the sketch
which is three, four lines, only vaguely like the actual shape of the
thing. With the measurements "slapped" on. _I_ could build it, but
then I know what I want, etc,etc,etc.

Trivial example.

If, however, I want to have some one else do it, I will need to be
much more specific in my drawing, but I do not need all the "formal"
methodology, including the title block and blah, blah.

Fitting a desk into a room?

On the gripping hand, if I want to go into production (start a
company), I will need to have a full set of Orthogonal Drawing in the
Standard Projections, with indication of whether first or third order
perspective used, materials used, and any details "not obvious" called
out or indicated on the drawing.

Are you now arguing that drafting is no longer needed?

Realize that some where in the files of the Everbilt Company, is a
set of drawings specifying the dimensions of a "1/4 inch washer". Most
likely drawn with dimensions A, B, C, with a table of size dimensions
(width, thickness, hole size) and material options (Brass, Stainless
steel, 'steel', etc, etc etc.)

There are standards for such things. If you don't like standards,
just pull out the McMaster-Carr catalog.

All that is a long way of saying, some times a drawing just needs
to have general shape and overall dimensions, some times you get out
the drafting kit "just because" you want a precise drawing of the
thing.

"Drafting kit" = 3-D modeling

And we're back to one of my hobby horses, "how precise is enough?"
If I'm painting a room, do I need to know that wall is 365.8 cm long,
or will 3 1/2 meters do? Does _this_ drawing have to be "to scale" or
"exact shape", or is 'close enough' sufficient.

What does this have to do with the price of oats in China? If I'm
painting a room, I start with, oh, about that many gallons. If I
guessed too little, it's only a trip to the paint store. If I bought
too much, well, there's always another room. I don't measure or draw
*anything*.

I realize that one does not need to know about whatshisnames
experiments into latent heat in order to make coffee; nor does one
need to does not need to know about Leo Baekeland and his invention in
order to in order to use a Kerug pod. Neither are you required to
know the role of romantic entanglements which lead to the
establishment of British coffee plantations in Jamaica. One simply
has to know "Go to the cupboard, get the box!"

I mean, is it really necessary to understand how credit in the
early 15th century lead to the development of GPS, Cell phones and
SpaceX in order to place a call? No.

But it is still a cool subject to look into.
