When designer designing a new engineering drawing, they will refer to the previous valid design document that same or nearly match with their new design specification. Previous design have been reviewed, analyzed and proven to be successful. By using the previous design, it likely saves significant resources and manpower. In real situations, engineering drawing is usually in large quantities and not in order. This paper describes a research and development of an extraction technique in the field of engineering drawing. Non-geometry information that will be emphasis in this research is information that available in the title block.
