Geometric Tolerance Of Computer-aided Query And Annotation Software Design

Agricultural mechanization has a very strong color, and the era of progress,update, i get a direct reflection of modern civilized and progressive developmentof science and technology. In particular, agricultural machinery manufacturingprecision, and the precision with fixative level and quality of various machinesand toward the quality of one of the relative importance. full computer-aideddesign (CAT) tolerance for a fitting design (DFA) important content, itcontributes to reduce product development cycles, improving products qualityand reduce costs and application prospect.AutoCAD is a function is very powerful drawing software, with the tools andannotation AutoCAD method marked by a tolerance, usually by mechanicaldesign manual for tolerance, both long and arduous and slow, and easy mistakecannot be achieved by a tolerance of query and annotation.In this research in computer-aided designing the parts for tolerance andunderstanding, the overall analysis of the key to shape a tolerance of acomputer-aided designing technology to study.By this research and developmentand achieve a man of tolerance in a cad. The query to find and note a marked bytolerance, to form a most types of computer aid automatically created to provideconvenient.
