A CAD graph processing system based on the network

A CAD image processing method and a system based on network includes: a principle controller, which can access and convert CAD image files and distribute the files content on other clients for processing, after that, accept processed image information from other clients and represent the information thereon; at least a client, which is used to receive the image information from the principle controller and return the processed image information to the principle controller after processing. The principle controller includes: a CAD image information storage device (1) and a client data receiving device (8) used to receive CAD image parallel processing unit information and CAD image processing order information from network. The principle controller is connected with the client by computer network. The invention greatly improves processing speed and efficiency of large-scaled CAD image task.
