Abstract: A conversion processing method, device and computer program product. The device includes a memory for storing drafting data, a selector for choosing the drafting data stored in the memory, a converter for converting the drafting data chosen by the selector into shape data, and a transmitter for transmitting the shape data to a browsing management server that stores the shape data and enables browsing the shape data via a communications network. The converter converts, from drafting data selected by the selector, the drafting data having a registration date and time corresponding to the date on which the converter has converted the drafting data, and that is also more recent than the registration date on which the drafting data is registered in the memory.

Abstract: The input-processing unit of the process control unit, which is installed in the intra-section browsing management server, makes image information of a dialog box by which users can specify the model name of a unit or a product that uses the component indicated by the 3-D shape data. Then, the input-processing unit sends the information to the client terminal, and makes it display the information on the screen of the display-processing unit. When model names are specified on the client terminal, the output-processing unit reads the 3-D shape data stored in the folder with the same name as the specified model names.
