=======
The development of AutoCAD can be divided into five stages: primary stage, development stage, advanced development stage, perfect stage and further perfect stage.
initial stage
Autocad1.0 ——198211month
AutoCAD1.2 ——1April 983
AutoCAD1.3 ——1August, 983
Autocad1.4 ——198310 month
Autocad 2.0-198410 month
stage of development
Autocad 2.17 ——1May, 985
Autocad 2.18 ——1May, 985
Autocad 2.5 ——1June, 986
Autocad 9.0 ——1September, 987
AutoCAD 9.03——
Advanced development stage
AutoCAD10.0 ——1August, 988
Dialog boxes of graphical interface began to appear, and the functions of CAD were relatively complete.
AutoCAD 1 1.0—— 1990
AutoCAD 12.0—— 1992
Dos version is the peak, with mature and complete functions, and provides a perfect AutoLisp language for secondary development. Many professional CAD of mechanical structure and circuit design are developed on this version. This version has many functions that the current version does not have. For example, 3Dface is obtained after the explosion of a solid, instead of becoming a surface solid or solid like the current version, and unlike 3Dface, vertices can be stretched separately.
