Abstract: In order to deal with the problem that the large amount of transmission data of a model in the collaborative feature modeling, this paper proposes a new feature-based descriptive semantic-collaborative modeling method. The semantic description of the features for a product’s model that described by XML is analyzed. For ensuring that the modeling do not depend on the created sequence of features and maintaining the consistency of the design results with the design intent, this article also puts forward a model’s constructing method which driven by the features. This drive mode was based on the constraint relationship between the father element feature and son element feature. This approach also helps to improve the efficiency of design. Finally, the local recognition, extraction and network interaction of the feature semantics increment file are studied. By transmitting only incremental semantic that described by XML, the collaborative modeling with low network traffic load can be realized in principle.
