Because it forms, there is an advantage that it is possible to easily create the component management data and CAD data with a simple configuration.

  That is, when the operator newly designs a vehicle part by using the CAD device B or changes the design to create new CAD data, the parts configuration included in the CAD data and the parts of the vehicle It is determined whether or not there is a one-to-one correspondence with the component configuration included in the component management data for managing the configuration, and a drawing identification number assigned with an identifier corresponding to the determination result is added to the CAD data. The drawing identification number of the CAD data and the parts management created separately from this, without requiring complicated work such as creating a parts table of parts management data corresponding to the design change. Corresponding to the parts list of data. Accordingly, when the CAD data is read from the storage means 3 and displayed on the display means 4 by looking at the parts table of the parts management data, the part configuration and the part identification number included in the CAD data given the drawing identification number are The CAD data can be analyzed after accurately recognizing whether or not the component configuration of the given component management data has a one-to-one correspondence based on the identifier.

  For example, in the above-described embodiment, when the part configuration included in the CAD data includes an extra part such as a mounting bolt with respect to the part configuration included in the part management data, the drawing identification number assigning unit 2 controls the container.

If the part configuration included in the CAD data has a missing part with respect to the part configuration included in the part management data, the identifier D is assigned. If the number assigning unit 2 is configured to assign the identifier L, which is an abbreviation of “Lack”, to the subordinate to the drawing identification number, the identifier of the drawing identification number displayed on the display unit 4 is confirmed. There is an advantage that it is possible to easily and appropriately recognize the relationship between the component configuration included in the CAD data and the component configuration included in the component management data.

  The extra parts or the missing parts included in the CAD data may be standardized small parts such as bolts, nuts, clips, grommets, or harnesses, and are included in the CAD data to which the drawing identification number is assigned. The identifier is used only when the component configuration is compared with the component configuration included in the component management data to which the component identification number is assigned and the CAD data includes or lacks these small parts. It is desirable that D or L be added to the drawing identification number.

  That is, as shown in the above embodiment, in the parts management apparatus A, the small parts and the vehicle body parts to which the small parts are attached are individually managed, and these are designed integrally in the CAD apparatus B. In such a case, it is inevitable that the parts configuration included in the CAD data and the parts configuration of the part management data do not correspond one-to-one. In addition, even when the accessory part and the vehicle part are integrally managed as the purchased part by the parts management apparatus A and the vehicle part design excluding the accessory part is performed by the CAD apparatus B, There arises a situation in which the component configuration included in the CAD data and the component configuration of the component management data do not correspond one-to-one. In such a case, the component configuration included in the CAD data to which the drawing identification number is assigned by the drawing identification number assigning unit 2 and the component configuration included in the component management data to which the component identification number is assigned are one-to-one. If the identifier indicating that it does not correspond to the above-mentioned drawing identification number is assigned, the drawing identification number of the CAD data is assigned to the parts table of the parts management data created separately from this. There is an advantage that it can be easily handled.

  Even if the part configuration included in the CAD data and the part configuration included in the part management data match, this mounting state is different if the mounting state of the parts in the CAD data is different. The identifiers indicating that they are different may be assigned by the drawing identification number assigning means 2 so as to be subordinate to the drawing identification number. For example, in the case where the same type of engine body is disposed in the engine room in a vertical state in a certain vehicle type, and is disposed in the engine room in a horizontal state in another vehicle type, a CAD device In B, since the design according to the mounting state of the engine body is performed, different CAD data is created even for the same type of engine body.

  Therefore, when, for example, LXXX-0200 is assigned as the component management number of the engine body by the component identification number assigning means 1, the engine is placed vertically by the drawing identification number assigning means 2 as shown in FIG. The drawing identification number to which the identifier B00 indicating that the engine is disposed in the engine room or the identifier B0A indicating that the engine is disposed horizontally in the engine room is given at the end, that is, the above parts A drawing identification number LXXX-0200 B00 or LXXX-0200 B0A composed of a combination of the component identification number BLXXX-0200 of the management data and the identifier B00 or B0A is created by the drawing identification number assigning means 2 and this drawing identification is made. It is preferable to assign a number to the CAD data.

  When the component configuration included in the CAD data matches the component configuration included in the component management data as described above and the mounting state of the component in the CAD data is different, the drawing identification number assigning means 2 In the case where the identifier indicating that the mounting state is different is provided so as to be subordinate to the end of the drawing identification number, the mounting state of the vehicle parts is set for each vehicle type using the CAD device B. When creating CAD data by changing the design, etc., a plurality of CADs with different component mounting states are not required, such as creating a new parts table of parts management data corresponding to this design change. There is an advantage that the existence of data can be easily recognized based on the identifier of the drawing identification number.
