Study on Key Technology of Three-Dimensional Parametric Modeling of Common Standard Components of Chemical Equipment

The common standard components of chemical equipment are mainly used for connecting, fastening and supporting the chemical equipment. Because of its wide varieties and complicated shapes, the three-dimensional parametric programming is relatively difficult. The system takes AutoCAD system as development platform, adopts VBA, Vlisp programming language and dialog box development technology and conducts a detailed study on the geometric figures of various common standard components, standard data sheets and others. The "three-dimensional parametric modeling system of common standard components of chemical equipment" is thus developed and it can provide correct three dimensional physical models of standard components in a convenient, accurate and fast manner. In this way, its three dimensional design is digitalized and automated. In addition, it lays a solid foundation for future three-dimensional digital simulation and virtual design of chemical enterprises.
