Information capturing method based on CAD electrical schematic diagram

According to the information capturing method based on the CAD electrical schematic diagram, the drawing is rapidly converted into the report form by developing the CAD plug-in, on one hand, drawing tabulation checking is achieved, and the design accuracy and design quality are improved; and on the other hand, information needed by equipment production and purchase is supported through the extracted equipment information report, and the function of automatically extracting related mass information from CAD drawings is achieved. According to the method, for the intricate and huge-data-volume electrical schematic diagram, the connection relation between the equipment and the cable is rapidly captured on the basis of following the logic relation of the schematic diagram, a report for drawing checking and equipment production related information is provided, and the efficiency of related work is greatly improved. On the basis of following the logical relationship of the electrical schematic diagram, manual extrac
