Analysed　the　advantages　of　3D　configuration　software　and　the　issues　which　need　to　be　resolved.　Proposed　the　design　method　of　semantic-based　intelligent　component　library.　Using　ontology　to　describe　the　graphics　components　of　the　3D　configuration　software.　Analysed　the　feasibility　of　using　Ontology　in　the　3D　configuration　software.　Proposed　the　architecture　of　the　3D　intelligent　components.　And　described　the　method　of　describing　the　3D　components　using　ontology.　Depending　on　the　support　of　the　ontology　library,　it　can　reduce　the　complexity　and　difficulty　to　create　the　3D　monitor　scene　by　the　3D　configuration　software　using　the　intelligent　components.　This　makes　the　automation　engineers　create　3D　monitoring　scene　so　easily　who　has　no　3D　experience　in　the　3D　development.
