Abstract :
An object-oriented drawing understanding system named OO-Mudams, which can flexibly adapt to various types of drawings by defining their model, is proposed. OO-Mudams is a model-driven system, with reasoning engine, management of internal database for reasoning results, and model definition for users. By defining the models, the system can be customized to process various kinds of drawings including engineering drawings and layout drawings. In order to manage huge reasoning result space effectively, the system uses an efficient multidimensional data structure named BD-tree, and, to facilitate the reasoning process, the TMS (truth maintenance system) is used to maintain the dependency among reasoning results. OO-Mudams is characterized by its flexible object-oriented system structure and an object-oriented language for defining the model of target objects
