Description

  The present invention relates to a design support apparatus using CAD data in a field related to a plant life cycle such as estimation, design, construction, operation, and maintenance of a plant.

  For example, in the manufacturing industry of power plants such as nuclear power and thermal power, design data and local conditions must be changed in accordance with local conditions throughout the plant life cycle such as design stage, construction stage, operation / maintenance stage, and disposal stage. There was a problem that the divergence of became larger. In other words, the equipment shape, which had a relatively simple shape at the design stage, must be changed based on the shape of the actual equipment that can be procured and the shape of the equipment placed on the site. It is necessary to take into account errors related to local management. Therefore, there is a need to make the shape of the device as detailed as possible.

  If such a device shape is prepared as a reusable model in an easy-to-use format in plant CAD, it is effective to create CAD data for detailed estimation in a short period of time. It becomes easy to correct the data according to the actual local situation. However, it is a burden on the designer to prepare the device model in a format that can be adjusted in detail at the initial stage of design.

  In “3D modeling system having parametric function and parameter editing method using the same system” shown in [Patent Document 1], parameter items in 3D model design are manually edited.

  However, with this method, since the user needs to devise parameters necessary for creating the device model, and to create, edit, and input the parameters, the input operation becomes complicated when the device has a complicated shape.

  A general CAD data input method for plant CAD will be described with reference to FIGS.

  First, a specific device shape 1210 is generated using the device 3D model library 320 and the device attribute data 330 using the device modeler 120. A plurality of equipment shapes are determined as necessary equipment for the plant. The device shape thus prepared is transferred to the arrangement design CAD 110 and arranged with respect to the coordinate origin 1100 of the plant building. Also, additional shapes that have not been created in advance by the device modeler can be connected to the device 3D model, for example, as additional shapes 1220 and 1230. That is, a shape that can be recognized as a device created by parameter transformation and a shape that is as close as possible to the actual construction status can be reproduced with the device shape details adjusted by simply adding a shape.

The device 3D model library manages data in a table composed of columns consisting of device type, device type, device coordinate system origin, primitives constituting the device, connection relationship between primitives, and related attribute IDs. . For example, for the combustion apparatus type A, the origin in the equipment coordinate system is the top left corner of the equipment, and the component primitives (geometric elements) that compose the shape of the equipment are created by sweeping a rectangular parallelepiped (PBOX1) and a triangle It consists of a solid (PTR1). If the primitives are connected in such a situation, a description is made so that the northeast of the bottom surface of the first primitive and the northeast of the top surface of the second primitive coincide between the two primitives.
