  • Patent number: 11176283
    Abstract: A shape search unit (22) that repeats processes of comparing each shape element of current shape data (11a) or previous difference shape data (12a) with each shape element of existing shape data (11b), setting a set of shape elements that are similar to each other as a result of the comparison as common shape data (12b), on the other hand, and setting a set of shape elements that are not similar to each other as next difference shape data (12a), until the common shape data (12b) is not extracted from the difference shape data (12a), a common mesh extraction unit (23b) that searches for corresponding common mesh data (13b) from an existing model database (11x) using the common shape data (12b) as a search key are provided.

  • Publication number: 20210334421
    Abstract: Generation of a search key shape for identifying a dedicated shape with respect to three-dimensional CAD data is facilitated. A shape group registration unit registers multiple pieces of three-dimensional CAD data; a feature amount computation unit computes a feature amount with respect to each of the registered pieces of three-dimensional CAD data; a clustering unit clusters the pieces of three-dimensional CAD data based on a feature amount; a cluster center computation unit determines a feature amount of a cluster center of each cluster from a feature amount of three-dimensional CAD data; and a search key shape registration unit registers feature amount data of a cluster center as feature amount data of a search key shape.

  • Publication number: 20200401737
    Abstract: A plurality of 3D CAD data which has been commercialized in the past and released is extracted according to a design rule. A main feature amount is measured for each of the plurality of 3D CAD data extracted. A related feature amount defined according to the main feature amount is acquired or measured for each of the plurality of 3D CAD data extracted. A statistical value based on the main feature amount and the related feature amount is calculated. The statistical value is visualized in order to identify an allowable range of the main feature amounts or related feature amounts that are highly related to the main feature amount.

  • Publication number: 20200334399
    Abstract: A design support system for verifying 3D-CAD data includes a common module database storing a plurality of common modules for processing the 3D-CAD data, a rule file database which stores a plurality of rule files for defining a procedure for obtaining a verification feature amount from the 3D-CAD data, and violation information based on the verification feature amount using the common module, and a design support apparatus. The design support apparatus calls a common module according to the procedure defined in the rule file and executes the common module on the 3D-CAD data, and determines whether the design requirement is violated on the basis of the violation information defined in the rule file and the verification feature amount obtained according to the procedure.

  • Patent number: 10628619
    Abstract: The present invention enables easy generation of analysis mesh data from larger CAD data including complicated partial shapes without performing shape division of CAD data. An analysis mesh data generating device comprises: a storage device configured to store CAD data, model CAD data, and model mesh data associated with the model CAD data; and a control device. The control device searches for model CAD data similar to a partial shape in the CAD data from the model CAD data stored in the storage device, obtains model mesh data associated with the retrieved model CAD data from the storage device, calculates an application position of the model mesh data at analysis mesh data generated from the CAD data, deletes mesh data relate with the partial shape in the analysis mesh data, and combines the model mesh data at the calculated application position.

  • Publication number: 20190095839
    Abstract: A design support device supports a design project achieved by executing a plurality of tasks including subtasks. The design history data of the design performed by a designer is sequentially stored and associated with a task to sequentially generate task-design history relevant data. A subtask is defined with respect to the task-design history relevant data to sequentially generate design process data. Subtask relevant data indicating a relevance between subtasks with respect to the plurality of pieces of design process data is generated, and a subtask to be performed in a later design work is estimated with respect to an in-process design work from a difference between past design process data of a project performed in the past and in-process data in a project performed currently to obtain an estimate subtask. An optimal execution order is calculated to obtain estimate design process data and the estimate design process data is output.

  • Publication number: 20180052948
    Abstract: A mesh is manufactured in consideration of the differences between the specification of the mesh to be manufactured for each portion to be analyzed, the difficulty in defining the mesh specification, and the response to the change in the mesh specification. Analysis mesh manufacturing equipment has first means for registering, as an uncorrected sample, a combination of partial mesh data for a correction examining portion and CAD data associated therewith to a mesh correcting sample database, second means for storing mesh data and CAD data that are to be inspected, third means for retrieving, with respect to the mesh data and the CAD data that are to be inspected, a partial mesh that is similar to the mesh data and the CAD data of the uncorrected sample that are registered to the mesh correcting sample database, and fourth means for highlighting the retrieved partial mesh on a display device.
