Prior to the proliferation of software, namely Adobe and Aldus, a designer needed an entire toolbox full of things to get a job done.
From t-squares and triangles, to ruling pens, masking tape, photo tape, rubber cement, spray glue, brushes, guache, drawing tables, technical pens, matte board, acetate, pica poles, french curves, proportional wheels, type spec books, etc.
What analog tools (not software or computer-based) should every designer have today and be comfortable using, and why?
Has software made all analog tools completely obsolete?
