In this paper, we present a retrieval method of drawing image databases. The method is intended to assist retrieval performed by tracing lines in the drawings where symbols and lines describe connections between components. This method is based on the viewpoint transition model which we propose in this paper. In this model, a database retrieval is described as a process of viewpoint transition in the data space. The viewpoint transition is controlled by the rules designed for each application.This method has a feature that the aim and situation of a retrieval are properly reflected to the results of the retrieval, compared to former methods such as the hyper-link method.We implemented this method to the plant diagram database which is used as a help to plant control and maintenance. The effectiveness of this method is confirmed in the experiment which is performed supposing the situation that an operator gathers the plant informations to determine the cause of abnormality when a meter detects it.
