A SYSTEM FOR FORM-FEATURE-BASED INTERPRETATION OF TECHNICAL DRAWINGS

An approach to high-level interpretation of technical drawings is illu strated and TECNOS, a rule-based, data-driven prototype, is described. TECNOS exploits a metalinguistic level of reasoning and a lexicon of user-defined form features to translate a manually generated technical drawing into a formally defined description. The language of technica l drawings and the metalanguage for applying the rules to it are defin ed by the same formalism that allows the use of only one interpreter t o control and execute the translation process.
