Rough sketches are different than crudely-drawn diagrams. In fact,
many rough sketches are very well drawn: http://tinyurl.com/2a27ed
I¹ve been doing concept sketches for a lot of years, and the majority of
these examples are not rough sketches, no matter what the authors or Google
call them. The first example on Jared¹s site ( of the space station ) is
more like it. The second example is way to finished IMHO.
Transforming an idea in your head into a sketch with a few well placed lines
and scribbles on the back of a napkin that communicates is an art that
should be part of every designers toolkit, in whatever medium. Like a lot of
tactile, hands-on ways of working, sketching is becoming a lost art for many
of us. One of the downsides of our dependence on drawing software, is we
(and clients) get too focused on finished-looking products.
Better to spend five minutes to do five quick idea sketches, refine one that
seems to be working and then maybe fire up the drawing or prototyping
program. Adding to some of the previous ³Prototyping Tools² threads, rough
concept sketching and paper prototyping are very freeing and seem bring an
element of play and exploration to the process.
Not everyone¹s a visual thinker or can understand a ³rough² so audience and
level of understanding is important.
All these tools have there place in the process. See www.sketchup.com for an
interesting ³sketchy² program that uses lines that go through the endpoints
as Buxton mentions, but keep your number 2 pencil sharp.
