All the different skills

Skills, for designers, are sets of tools used by a designer or someone in their craft to explain to others their ideas and thoughts in a mainly visual way.

I think by having the education that we do being so standard, that it is impossible to say that we have different skill sets, the biggest thing that I can deduce, and many others as well is to identify those skill sets that best fit a designers need at any given time, or is best for them to accurately explain ideas to others.

Some can do it with thumbnail sketches, others with CAD modeling, and yet others marker renders. its up to you, the job at hand, and how the audience your talking to will best receive it.
