【Abstract】 A new inputting mode in CAD system of machine elements is proposed in the paper. With it some aspects of the system, such as usableness, robustness, flexibility of in- putting, editting and modification of data, as well as management of information re- sources, are much improved, Hence it offers users a desired interfacing environment.更多还原
