The designer's intention is the essence of design. But the geometric information is the only one that we handle in the conventional CAD system. In this paper, we propose the description model of designers' intention that might be helpful to reduce the troubllesome communications among the designers. The designers' intention is described as the correlation using the required funtions, the binding conditions, the technical information, the connotational assignments and the geometric information. The required functions are represented by a tree structure to show the sequence of designers' consideration. The lowest function is assigned to the functional elements that are selected from the geometric information according to the connotational assignments. Additionally, the binding conditions and the technical information are related to the functional elements. The effective usage of designers' intention model is verified under the redesign process. It shows that the redesign is processed successfully using the designers' intention.
