Description

本発明は、設計装置に関する。 The present invention relates to a design device.

立体的形状を有する自動車部品及び部材は、主として3DCADを用いて、3D空間上で設計される。3DCADにより、3次元モデルとして生成されたデータは、別途、正面図、平面図、側面図及び所定の断面図を各々示す2次元モデルに還元され、当該2次元モデルは試作品の製作、又は生産工程で活用される。 Automobile parts and members having a three-dimensional shape are designed in 3D space mainly using 3D CAD. The data generated as a three-dimensional model by 3DCAD is separately reduced to a two-dimensional model showing a front view, a plan view, a side view, and a predetermined cross-sectional view, and the two-dimensional model is used for production or production of a prototype. Used in the process.

3次元モデルから2次元モデルを生成するには、3DCADデータが示す立体を、正面図、平面図、側面図及び所定の断面図の各々に対応する平面に投影する。また、3DCADデータは設計用のデータであるから、各部の寸法、注釈及び注記(以下、「注記等」と略記)等が存在する。正面図、平面図、側面図及び所定の断面図の各々は、3次元モデルの一平面のみを表示するので、かかる注記等を各々の平面に割り振ると共に、各々の平面図上で注記等の各々が重なり合うことがないように見やすく配置することを要する。しかしながら、注記等の配置は手作業によるので、作業が煩雑であると共に、作業ミスが懸念されてきた。 To generate a two-dimensional model from a three-dimensional model, the solid indicated by the 3D CAD data is projected onto a plane corresponding to each of the front view, the plan view, the side view, and the predetermined cross-sectional view. Further, since the 3D CAD data is data for designing, there are dimensions, annotations, notes (hereinafter, abbreviated as “notes and the like”) and the like of each part. Since each of the front view, the plan view, the side view, and the predetermined cross-sectional view displays only one plane of the three-dimensional model, such notes and the like are assigned to each plane and each of the notes and the like on each plan view. It is necessary to arrange them in an easy-to-see manner so that they do not overlap. However, since the arrangement of notes and the like is done manually, the work is complicated and there is a concern about work mistakes.

特許文献1には、注記等が、平面図を構成する各図面間で重なり合うことがないようにレイアウトすることを可能とする設計装置の発明が開示されている。 Patent Document 1 discloses an invention of a design device that enables a layout such that notes and the like do not overlap between the drawings constituting the plan view.

ステップ300では、3D注記42A、42B、42C等の矢先の座標を抽出する。図4は、3D注記42A、42B、42Cの各々の引出線44A、44B、44C及び矢先46A、46B、46Cの一例を示した概略図である。3D注記42A、42B、42Cの各々の引出線44A、44B、44C及び矢先46A、46B、46Cは、各々、孔部32A、32B、32C等の構成の各々を示している。ステップ300では、かかる矢先46A、46B、46Cの各々の座標をH(一例としてZ軸に相当)、L(一例としてX軸に相当)及びW(一例としてY軸に相当)の3次元座標系で抽出する。図4では構成の各々を孔部32A、32B、32Cとしたが、部材によっては突起部等に3D注記が付される場合がある。従って、本実施の形態に係る設計装置10では、孔部32A、32B、32C以外の突起部等の構成も、後述する中心座標の算出及び投影面積の算出を行い、当該構成に係る3D注記を正面図、側面図及び平面図に各々分類する。 In step 300, the coordinates of the arrowheads of the 3D notes 42A, 42B, 42C, etc. are extracted. FIG. 4 is a schematic view showing an example of the leader lines 44A, 44B, 44C and the arrowheads 46A, 46B, 46C of the 3D notes 42A, 42B, 42C, respectively. The leader lines 44A, 44B, 44C and the arrowheads 46A, 46B, 46C of the 3D notes 42A, 42B, 42C respectively indicate the configurations of the holes 32A, 32B, 32C, etc., respectively. In step 300, the coordinates of each of the arrow tips 46A, 46B, and 46C are three-dimensional coordinate systems of H (corresponding to the Z axis as an example), L (corresponding to the X axis as an example), and W (corresponding to the Y axis as an example). Extract with. In FIG. 4, each of the configurations is a hole 32A, 32B, 32C, but depending on the member, a 3D note may be added to the protrusion or the like. Therefore, in the design device 10 according to the present embodiment, the configuration of the protrusions other than the holes 32A, 32B, and 32C also calculates the center coordinates and the projected area, which will be described later, and makes a 3D note relating to the configuration. It is classified into a front view, a side view, and a plan view.

ステップ302では、孔部32A、32B、32Cの各々の中心座標34A、34B、34Cを算出する。孔部32A、32B、32Cが円であれば、孔部32A、32B、32Cの各々の直径と矢先46A、46B、46Cの各々の座標から、中心座標34A、34B、34Cを算出できる。孔部32A、32B、32C等の構成が略長方形又は楕円等の円以外の場合も、各々の幾何学的な定義に従って中心座標を算出する。 In step 302, the center coordinates 34A, 34B, 34C of the holes 32A, 32B, 32C are calculated. If the holes 32A, 32B, and 32C are circles, the center coordinates 34A, 34B, and 34C can be calculated from the diameters of the holes 32A, 32B, and 32C and the coordinates of the arrow tips 46A, 46B, and 46C. Even when the structure of the holes 32A, 32B, 32C, etc. is other than a circle such as a substantially rectangular shape or an ellipse, the center coordinates are calculated according to the respective geometrical definitions.

ステップ304では、孔部32A、32B、32Cの各々の構成の投影面積を正面視、側面視及び平面視の各々で算出し、ステップ306では、孔部32A、32B、32Cの各々の3D注記42A、42B、42Cを、孔部32A、32B、32Cの各々の投影面積が最大となる面視に分類する。図5は正面視、図6は側面視、図7は平面視の各々の一例である。孔部32A、32B、32Cの各々の投影面積は、図5の正面視で最大となるので、ステップ306で3D注記42A、42B、42Cを正面視に分類する。 In step 304, the projected area of each configuration of the holes 32A, 32B, 32C is calculated for each of the front view, the side view, and the plan view, and in step 306, the 3D note 42A of each of the holes 32A, 32B, 32C is calculated. , 42B, 42C are classified into a plane view in which the projected area of each of the holes 32A, 32B, 32C is maximized. 5 is an example of front view, FIG. 6 is a side view, and FIG. 7 is a plan view. Since the projected areas of the holes 32A, 32B, and 32C are the largest in the front view of FIG. 5, the 3D notes 42A, 42B, and 42C are classified into the front view in step 306.

ステップ308では、各面視で3D注記42A、42B、42Cの各々が互いに重ならないように平面に並べる。 In step 308, the 3D notes 42A, 42B, and 42C are arranged in a plane so as not to overlap each other in each aspect.

図8は、正面視に3D注記42A、42B、42Cを分類した直後の状態を示した概略図である。図8に示したように、3D注記42Cは平面化されておらず、3D注記42Aと3D注記42Bとが重なっている。ステップ308では、3D注記42Cを平面化し、3D注記42Aと3D注記42Bとが重ならないように配置する。ステップ308では、一例として、3D注記42Cを分類先の面視が示す平面と同一平面に配置するように処理すると共に、当該同一平面上の3D注記42Aの領域と3D注記42Bの領域とが干渉した場合に、両者を引き離す処理が実行される。ステップ308で3D注記42A、42B、42Cを並べた後は、処理を終了する。 FIG. 8 is a schematic view showing a state immediately after classifying 3D notes 42A, 42B, and 42C in a front view. As shown in FIG. 8, the 3D note 42C is not flattened, and the 3D note 42A and the 3D note 42B overlap each other. In step 308, the 3D note 42C is flattened and arranged so that the 3D note 42A and the 3D note 42B do not overlap. In step 308, as an example, the 3D note 42C is processed so as to be arranged in the same plane as the plane indicated by the plane of the classification destination, and the region of the 3D note 42A and the region of the 3D note 42B on the same plane interfere with each other. If so, the process of separating the two is executed. After arranging the 3D notes 42A, 42B, and 42C in step 308, the process ends.

図9、図10、図11、図12は、各々、本実施の形態に係る設計装置10によって3次元モデル30から生成された2次元モデルである正面図、側面図、平面図、及び図2に示した断面指示線40に従った断面図の各々の一例を示している。正面図、側面図及び平面図にはH、L、Wの各座標が設定されている。 9, FIG. 10, FIG. 11, and FIG. 12 are a front view, a side view, a plan view, and FIG. 2, which are two-dimensional models generated from the three-dimensional model 30 by the design device 10 according to the present embodiment, respectively. An example of each of the cross-sectional views according to the cross-sectional instruction line 40 shown in the above is shown. The coordinates of H, L, and W are set in the front view, the side view, and the plan view.

特注記36は、一例として側面図に付したが、正面図に付してもよい。また、断面図において、注意事項等を記載した注記文50を入力してもよい。 The special note 36 is attached to the side view as an example, but may be attached to the front view. Further, in the cross-sectional view, the note 50 in which the precautions and the like are described may be input.

以上説明したように、本実施形態によれば、3次元モデルの孔部等の構成の投影面積を正面視、側面視及び平面視の各々で算出し、投影面積が最大となる面視に3D注記を分類することにより、3DCADデータと2DCADデータとの対応付けを自動的に行うことができる。3D注記の分類は、孔部等の構成の中心座標又は3D注記の矢先の座標から推定できるが、本実施の形態のように、構成の投影面積が最大となる面視に当該構成の3D注記を分類する方が、アルゴリズムは簡便であり、より正確な各面視への3D注記の分類が可能となる。 As described above, according to the present embodiment, the projected area of the configuration such as the hole portion of the three-dimensional model is calculated for each of the front view, the side view, and the plan view, and the projected area is 3D for the maximum projected area. By classifying the notes, the association between the 3D CAD data and the 2D CAD data can be automatically performed. The classification of the 3D note can be estimated from the center coordinates of the configuration of the hole or the like or the coordinates of the arrowhead of the 3D note. The algorithm is simpler and more accurate classification of 3D notes into each aspect is possible.

また、本実施の形態に係る設計装置10は、各面視に分類した3D注記を、例えば、分類先の面視が示す平面と同一平面に配置するように処理すると共に、同一平面上の3D注記の各々の領域が干渉した場合に、干渉している3D注記の領域を引き離す処理により、3D注記の各々を各面視が示す平面上に見やすく均等に配置する。その結果、3DCADによる3次元モデルから2次元モデルである正面図、平面図、側面図及び所定の断面図の各々を自動的に生成する設計装置を提供することができる。 Further, the design device 10 according to the present embodiment processes the 3D notes classified into each plane so as to be arranged on the same plane as the plane indicated by the plane of the classification destination, and 3D on the same plane. When each area of the note interferes, each of the 3D notes is arranged evenly and easily on the plane indicated by each view by the process of separating the areas of the interfering 3D note. As a result, it is possible to provide a design device that automatically generates each of a front view, a plan view, a side view, and a predetermined cross-sectional view, which are two-dimensional models, from a three-dimensional model by 3D CAD.

なお、本実施の形態に係る設計装置10においても、図3のステップ302で構成の中心座標を算出しているが、算出した中心座標に基づいて3D注記を各面視に前段階として分類してもよい。続くステップ304、306で構成の投影面積が最大となる面視を決定し、決定した面視と、中心座標に基づいて3D注記を分類した面視とが一致するか否かを判定するステップを加えてもよい。投影面積に基づいて決定した面視と中心座標に基づいて決定した面視とが矛盾しない場合は、両者の決定に基づいた面視に3D注記を分類する。両者の決定が矛盾する場合は、中心座標の算出、中心座標に基づく各面視への3D注記の分類、投影面積の算出及び投影面積に基づく面視の決定のいずれかに不具合があると思われるので、再度、構成の中心座標の算出から、構成の投影面積基づく面視の決定のステップを実行する。 Also in the design device 10 according to the present embodiment, the center coordinates of the configuration are calculated in step 302 of FIG. 3, but the 3D notes are classified as the previous steps in each aspect based on the calculated center coordinates. You may. In the following steps 304 and 306, a step of determining the surface view that maximizes the projected area of the configuration and determining whether or not the determined surface view and the surface view in which the 3D note is classified based on the center coordinates match. May be added. If there is no contradiction between the planes determined based on the projected area and the planes determined based on the center coordinates, the 3D notes are classified into the planes based on both decisions. If the two decisions are inconsistent, it is likely that there is a problem with either the calculation of the center coordinates, the classification of 3D notes for each aspect based on the center coordinates, the calculation of the projected area, or the determination of the aspect based on the projected area. Therefore, the step of determining the plane view based on the projected area of the configuration is executed again from the calculation of the center coordinates of the configuration.

さらに、本発明は、上記の形態例に限定されるものではなく、上記の形態例以外にも、その主旨を逸脱しない範囲内において種々変形して実施可能であることは勿論である。 Further, the present invention is not limited to the above-mentioned embodiment, and it is needless to say that the present invention can be variously modified and implemented within a range not deviating from the gist thereof other than the above-mentioned embodiment.

なお、特許請求の範囲における入力部は操作入力部24に、同演算部はCPU12に、各々相当する。 The input unit in the claims corresponds to the operation input unit 24, and the calculation unit corresponds to the CPU 12.
