Abstract: I-DEAS,as an advanced integrated mechanical CAD software applied in workstations which comprises design,analysis and manufacture,is a chief software in mechanical design.To counter I-DEAS's shortage of parts symbol library and draft management,we use I-DEAS powerful reciprocal administration system to establish a self defined mechanical parts library which has an audio-visual graph pre-view and selection system.This administration system not only has friendly interface but also has various convenient searching methods.
