Abstract
In the digital manufacturing,information circulation of engineering graphics can be realized in a short time by Internet inside enterprise and among enterprises.Manpower,material and financial resources are economized through the method and mistakes and redundancy of data obtained are also be cut down to maximum extent.Based on the characteristic of correlation of graphics'geometry elements,long唱distance high efficiency and secure transmission of complex engineering graphics data is realized after parameter structure is built and data code compression and data encryption are put in practice at the same time by using BP algorithm of artificial neural network.Examples show that this method can be used in actual engineering.
