History of CAD.

• <1980

• 1980: introduction of Autocad, first wide spread 2D drawing

software

• 1985: introduction of 3D software, first steps towards model

oriented software

• 1989: introduction of Pro/Engineer, first commercial

parametric modeler.

• Drawing oriented:

o Paper model

o Only on paper

o Multiplication of data

• Model oriented:

o CAD-model

o Virtual prototype

o 1 source of data

From drawing oriented to model oriented
