Based on AutoCAD ActiveX and VBA techniques and through carrying out the secondary development on AutoCAD2004,a kind of handy and easy to use automated generative system of parameterized drawing was built.The realization processes of automated generative system of drawing and the solving method for the key problems of programming were presented by living examples,thus provided reference-able method for further application of this technique.This system could produce detail drawings automatically according to parameters,and provided powerful tooling support for the development and manufacturing of serialized products,and possesses rather powerful applicable value.
