Computer-aided design is the use of computers to aid in the creation, modification, analysis, or optimization of a design. Designers have used computers for calculations since their invention.[1][2][3][4] CAD software was popularized and innovated in the 1960s, although various developments were made between the mid-1940s and 1950s. Digital computers were used in power system analysis or optimization as early as proto-"Whirlwind" in 1949. Circuit[5] design theory or power network methodology was algebraic, symbolic, and often vector-based.
