System for extracting text from CAD files

摘要

Text extracted from computer aided drafting (CAD) files is stored in a receiving database for use in document management. In addition, the textual data stored in the receiving database can be obtained from directory information, constants defined prior to processing the drawings, or pre-existing database(s). The textual data extracted from the CAD files are located by defining an extraction area and comparing the extent of the textual data with the boundaries of the extraction area. Any textual data within the boundaries are stored in a temporary file for transfer to the receiving database.
