　以下，本発明の実施例を，図面を用いて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　図１は，本発明のシステム構成である。設計プロセスデータ101，3DCADモデル102，設計ドキュメント103をデータ読込部104にて読込み，現在設計者が設計しているCADデータと類似するCADがあるかどうかをCAD・設計プロセス連動検索部105にて検索する。また，現在の設計プロセスと類似する設計プロセスがあるかどうかも検索する。 FIG. 1 shows the system configuration of the present invention. The design process data 101, 3D CAD model 102, and design document 103 are read by the data reading unit 104, and the CAD / design process linked search unit 105 determines whether there is a CAD similar to the CAD data currently designed by the designer. Search for. It also searches for a design process similar to the current design process.
　CAD検索部，設計プロセス検索部にて，関連するCADデータや設計プロセスが存在する場合は，CADデータや設計プロセスに関連付けられているデータを形状関連付けデータ表示部107にて表示する。関連付けされたデータに対して，現在作業中のCADデータへの新たな関連付けが必要な場合は，データ関連付け登録部108にて設計ドキュメントを登録する。 In the CAD search unit and design process search unit, if there is associated CAD data or design process, the CAD data or data associated with the design process is displayed on the shape association data display unit 107. When the associated data needs to be newly associated with the currently working CAD data, the data association registration unit 108 registers the design document.
　関連づけられたデータは，3DCAD，設計ドキュメント，設計プロセスを保管するデータベース109に登録しておき，検索できるようにする。 The associated data is registered in the database 109 that stores 3D CAD, design documents, and design processes so that they can be searched.
　続いて，データベースに登録された関連付けデータの検索において，設計変更を検討中の3DCADデータ110と，設計プロセス111をデータ読込部112にて読込む。関連付けされたデータに対して，類似する設計プロセス，CADデータがあるかどうかを類似設計プロセス，CAD検索部113にて検索する。検索した結果として，関連する設計ドキュメント115を関連ドキュメント表示部114にて表示する。 Subsequently, in the retrieval of the association data registered in the database, the data reading unit 112 reads the 3D CAD data 110 under consideration of the design change and the design process 111. The similar design process and CAD retrieval unit 113 retrieves whether there is similar design process and CAD data for the associated data. As a result of the search, the related design document 115 is displayed on the related document display unit 114.
　図２は，データの流れを示したものである。データ関連付け時には，設計プロセスデータ201，3DCADデータ202，設計ドキュメント203を読込む204。読込んだデータに対して，CAD検索部206では，設計ドキュメントを関連付けしようとする3DCAD205に対して類似するCADデータがあるかどうかを検索する。また，現在作業中の設計プロセス207に対して，類似する設計プロセスがあるかどうかを検索する209。検索した結果として，類似する3DCADデータ208,211と設計プロセスデータ210を表示し，関連付けられている設計ドキュメント213を形状関連データ表示部212にて表示する。設計者は表示されている設計ドキュメントを関連付け登録する214。 Fig. 2 shows the flow of data. At the time of data association, the design process data 201, 3D CAD data 202, and design document 203 are read 204. For the read data, the CAD search unit 206 searches for similar CAD data for the 3D CAD 205 to which the design document is to be associated. Also, a search is made 209 as to whether there is a similar design process for the design process 207 currently being worked on. As a result of the search, similar 3D CAD data 208 and 211 and design process data 210 are displayed, and an associated design document 213 is displayed on the shape related data display unit 212. The designer associates and registers 214 the displayed design document.
　続いて，設計ドキュメントを登録したCADデータを検索する。設計変更を検討しているCADデータ216と設計プロセスデータ217をデータ読込部218にて読込む。検討している設計内容に対して，類似するCADデータ，設計プロセスを検索する222。検索した結果，類似するCADデータ，設計プロセスが存在する場合は関連ドキュメント226を表示する225。 Next, search the CAD data that registered the design document.

Search for similar CAD data and design processes for the design content under consideration 222. If similar CAD data or design process exists as a result of the search, the related document 226 is displayed 225.
　図３は，設計コアモデル登録のフローチャートを示したものである。CADデータを読込み301，過去に設計した類似するCADデータがあるかどうかを検索する302。類似するCADデータが存在する場合は303，CADデータを表示する304。続いて，類似する設計プロセスを検索する305。設計プロセスが存在する場合は306，設計プロセスを表示する307。類似するCADデータ，設計プロセスに関連付けられている設計ドキュメント等のデータを表示し308，関連付け登録が行えるようにする309。続いて，検索する際のフローについて説明する。設計変更検討中のCADデータを読込む310。また，設計プロセスデータを読込む311。類似するCADデータが存在する場合312，CADデータと関連ドキュメントを表示する314。また，類似する設計プロセスが存在する場合315,316，類似設計プロセスと関連ドキュメントを表示する317。 Fig. 3 shows a flowchart of design core model registration. CAD data is read 301 and whether there is similar CAD data designed in the past is searched 302. When similar CAD data exists, 303 is displayed and CAD data is displayed 304. Subsequently, a similar design process is searched 305. If a design process exists, 306, and display 307 the design process. Display similar CAD data, data such as design documents associated with the design process 308, and enable registration 309. Next, the flow for searching will be described. Read 310 CAD data under consideration of design changes. The design process data is read 311. If similar CAD data exists 312, CAD data and related documents are displayed 314. If there are similar design processes 315 and 316, the similar design process and related documents are displayed 317.
　図４は類似するCADデータを検索する方法を説明した一例である。例えば，CADデータに関連する設計ドキュメントを登録する作業を行う際，CADデータと類似する過去のCADデータがあるかどうかを検索する。例えば，ねじのCADデータ402に対して，過去のCADデータ401があるかどうかを検索するためには，形状が類似しているかどうかを求める必要がある。形状が類似しているかどうかの検索は，例えば，〔特許文献３〕に記載の方法を用いてもよい。ここでは，形状表面に三角形メッシュを作成して403.404，三角形メッシュの面と面の成す角度や面と面の距離を求めて，特徴量を作成する。特徴量の近い形状を検索結果として示す。特徴量は，0～1で正規化しておき，閾値に近い形状があれば結果として表示されるようにする。 FIG. 4 is an example illustrating a method for searching for similar CAD data. For example, when registering a design document related to CAD data, whether there is past CAD data similar to the CAD data is searched. For example, in order to search whether there is past CAD data 401 with respect to screw CAD data 402, it is necessary to determine whether the shapes are similar. For example, the method described in [Patent Document 3] may be used to search whether the shapes are similar. Here, a triangular mesh is created on the shape surface and 403.404, the angle between the faces of the triangular mesh and the distance between the faces are obtained, and the feature quantity is created. Shapes with similar feature quantities are shown as search results. The feature quantity is normalized from 0 to 1, and if there is a shape close to the threshold, it is displayed as a result.
　図５は設計プロセスの検索アルゴリズムを示したものである。現在検討中の設計プロセス501にある，プロセス名やプロセスに繋がっているドキュメントからテキスト情報を抽出する502。テキスト情報503から名詞等の単語を検索キーワードとして取出し，検索キーワードを用いて，過去の設計プロセスを検索する504。検索キーワードが多く含まれている設計プロセスが存在する場合は，関連する設計プロセスとして出力する505。 Fig. 5 shows the design process search algorithm. Text information is extracted 502 from the process name and the document connected to the process in the design process 501 currently under consideration. A word such as a noun is taken out from the text information 503 as a search keyword, and a past design process is searched 504 using the search keyword. If there is a design process that contains many search keywords, it is output as a related design process 505.
　図６は，類似するCADデータを検索する画面を示したものである。画面には，ドキュメント関連付け601，ドキュメント検索606をメニューとして用意し，ドキュメント関連付けメニューは，新規にCADデータや，設計プロセスにデータを関連付け登録する際に必要な項目が表示される。類似CAD検索602，類似設計プロセス検索603，関連データ表示604，関連データ登録605項目を用意する。また，ドキュメント検索メニューは，設計ドキュメント等のデータが関連づけられた類似CADデータ607，設計プロセス608，関連するデータを検索して設計者に表示するために用意する609。 Fig. 6 shows a screen for searching for similar CAD data. On the screen, document association 601 and document search 606 are prepared as menus, and the document association menu displays items necessary for newly registering the association of CAD data and data with the design process. Similar CAD search 602, similar design process search 603, related data display 604, and related data registration 605 items are prepared.
