By utilizing object-oriented technology and unified data structure, the intelligent question band management system of engineering graphics for multiobject (IQBMS-EG) has been implemented. In order to ensure system security and realize resource sharing, the authorities of different objects are given properly. In the IQBMS-EG, besides the conventional modules of users management and the test question management, the test paper management module has been designed to group, analyze and typeset test papers. Of all, grouping test papers can be automatic or non-automatic, and automatic grouping test papers is achieved by using genetic algorithm, which makes procedure more objective, efficient and intelligent. For students, a users record management module is designed specially, which can realize special evaluation and comprehensive evaluation. In the paper, the design idea and mainly realize technology have been presented.
