Description

見積り装置、モバイル装置、および見積り方法Estimating device, mobile device, and estimating method
　本発明は、設計図から部品のコスト見積りを行う見積り装置、当該見積り装置を備えるモバイル装置、および前記見積り装置を用いた見積り方法に関する。 The present invention relates to an estimation device that estimates the cost of a part from a design drawing, a mobile device including the estimation device, and an estimation method using the estimation device.
　板金部品や切削部品等の部品の設計図には、曲げ加工制御データを算出するための断面図、貫き加工制御データを算出するための展開図等が用いられる。上述の断面図や展開図は、その大部分が、垂直線と、水平線と、曲率半径が一定の曲線（円弧）との組み合わせにより構成されている。 For a design drawing of a part such as a sheet metal part or a cutting part, a sectional view for calculating bending control data, a development view for calculating penetrating control data, and the like are used. Most of the above-mentioned sectional views and development views are composed of a combination of a vertical line, a horizontal line, and a curve (arc) having a constant curvature radius.
　従来、上述のような設計図の製図作業は、コンピュータ上のＣＡＤ（ｃｏｍｐｕｔｅｒ　ａｉｄｅｄ　ｄｅｓｉｇｎ）ソフト、またはＣＡＭ（ｃｏｍｐｕｔｅｒ　ａｉｄｅｄ　ｍａｎｕｆａｃｔｕｒｉｎｇ）ソフト等の設計支援ソフトを用いて行われていた。このような設計支援ソフトは、コンピュータに接続されたマウス、およびキーボートを用いることによって操作される。 Conventionally, the drafting work of the design drawing as described above has been performed using design support software such as CAD (computer aided design) software or CAM (computer aided manufacturing) software on a computer. Such design support software is operated by using a mouse and a keyboard connected to a computer.
　例えば、特許文献１は、ＣＡＤソフトを用いて板金部品の３次元（３Ｄ）設計を行う板金部品設計支援装置を開示している。この板金部品設計支援装置においては、マウスやキーボード等の入力装置からの入力操作により取得した板金部品のソリッドデータから、板金部品の端面を抽出している。このような板金部品設計支援装置では、マウスやキーボード等の入力装置を用いる必要があることから、製図作業は、コンピュータが配置されているオフィス等で行われることがほとんどであった。 For example, Patent Document 1 discloses a sheet metal part design support apparatus that performs three-dimensional (3D) design of a sheet metal part using CAD software. In this sheet metal part design support device, the end face of the sheet metal part is extracted from the solid data of the sheet metal part acquired by an input operation from an input device such as a mouse or a keyboard. In such a sheet metal part design support apparatus, since it is necessary to use an input device such as a mouse or a keyboard, the drawing work is mostly performed in an office or the like where a computer is arranged.
　一方、近年、入力装置としてタッチパネルを採用したＰＤＡ（Ｐｅｒｓｏｎａｌ　Ｄｉｇｉｔａｌ　Ａｓｓｉｓｔａｎｔ）、スマートフォン、タブレット型コンピュータ等のタッチパネル情報端末が広く普及している。このようなタッチパネル情報端末においては、指やタッチペンを用いて、液晶ディスプレイ等の画像表示部をタッチすることにより、図形の描写が可能である。このようなタッチパネル情報端末は、携帯が容易であり、また、指やタッチペン等を用いたタッチ操作により図形描写等の入力操作が可能であることから、ユーザーの利便性が高い。 On the other hand, in recent years, touch panel information terminals such as PDAs (Personal Digital Assistants), smartphones, tablet computers, etc., which employ a touch panel as an input device, have become widespread. In such a touch panel information terminal, a figure can be drawn by touching an image display unit such as a liquid crystal display using a finger or a touch pen. Such a touch panel information terminal is easy to carry and has a high user convenience because an input operation such as drawing a figure can be performed by a touch operation using a finger or a touch pen.
　また、携帯が容易なタッチパネル情報端末を用いて、部品の設計、およびコスト見積りをしたいという要求が存在する。何故ならば、携帯が容易なタッチパネル情報端末によって、部品の設計、およびコスト見積りが可能であれば、工場の製造現場、屋外等のマウスやキーボード等が通常備えられていない場所において、部品の設計図とコスト見積りを提示することができ、迅速な営業活動を展開することができるからである。 Also, there is a demand to design parts and estimate costs using a touch panel information terminal that is easy to carry. This is because, if the parts can be designed and the cost can be estimated with a touch panel information terminal that is easy to carry, the parts can be designed at a factory manufacturing site, outdoors, etc. where a mouse or keyboard is not normally provided. This is because a figure and a cost estimate can be presented, and a quick sales activity can be developed.
　しかしながら、指やタッチペンを用いたタッチ操作による図形描画では、タッチペンや指の動きのブレにより、正確な直線、円弧等を描くことが困難である。そのため、入力装置としてタッチパネルを採用したタッチパネル情報端末は、正確な線分による描画が必要とされる部品の設計図を製図するための装置として、不向きであった。 However, in drawing a figure by touch operation using a finger or a touch pen, it is difficult to draw an accurate straight line, arc, or the like due to motion blur of the touch pen or the finger. Therefore, a touch panel information terminal that employs a touch panel as an input device is unsuitable as a device for drawing a design drawing of a component that requires drawing with an accurate line segment.

And a CPU (Central Processing Unit) that executes a control program. When the control program is executed by the CPU, the estimation device 10 is controlled according to the control program, and various processes described in detail below are executed.
　見積り用パラメータＤＢ１２は、部品のコスト見積りを実行するためのパラメータが記憶されている。見積り用パラメータＤＢ１２には、例えば、製造原価２０２（図８参照）の見積りを実行するための材料費、加工段取り費、機械加工費、付帯加工費等のパラメータ、仕入原価２０３（図８参照）の見積りを実行するための材料費、外注費、汎用品の値段等のパラメータ、販売管理費、部品保管等の製造間接費見積りを実行するためのパラメータ、顧客毎の割引率、注文個数に応じた割引率、納期に応じた割引率等の条件係数等が記憶されている。なお、見積り用パラメータＤＢ１２に記憶されているパラメータは、必ずしもこれに限られない。部品のコスト見積もりに必要なパラメータであれば、如何なるパラメータであっても、見積り用パラメータＤＢ１２に記憶することができる。 The parameter DB 12 for estimation stores parameters for executing cost estimation of parts.

Any parameter can be stored in the estimation parameter DB 12 as long as it is a parameter necessary for cost estimation of the part.
　表示部１３は、画像を表示する液晶ディスプレイ等の画像表示部と、画像表示部に貼付けられたタッチパネルによって構成され、画像の表示機能とタッチ操作による入力受付機能の２つの機能、すなわちタッチパネル機能を有する。見積り装置１０のユーザーは、表示部１３の画像表示部に表示された表示画像１３０（図２を参照）を参照し、指やタッチペン等を用いて、表示部１３のタッチパネルに対してタッチ操作を行うことにより、見積り装置１０にデータを入力することができる。 The display unit 13 includes an image display unit such as a liquid crystal display for displaying an image and a touch panel attached to the image display unit. The display unit 13 has two functions of an image display function and an input reception function by a touch operation, that is, a touch panel function. Have. The user of the estimation device 10 refers to the display image 130 (see FIG. 2) displayed on the image display unit of the display unit 13 and performs a touch operation on the touch panel of the display unit 13 using a finger, a touch pen, or the like. By doing so, data can be input to the estimation device 10.
　ユーザーは、表示部１３のタッチパネル上の任意の１点に指やタッチペン等を接触させ、接触させたままの状態で接触位置を移動させ、接触を終了させる。このようなドラッグ（Ｄｒａｇ）操作によって、表示部１３のタッチパネルは、接触開始点および接触終了点間のタッチ点群を取得することができる。このタッチ点群は、取得された時系列順に番号付けされており、この番号順に各タッチ点を結ぶことにより、タッチ点群のベクトルを取得することができる。このタッチ点群のベクトルは、タッチ操作の移動ベクトルに対応するものである。ここで取得されたタッチ点群は、制御部１１のＲＡＭに一時記憶され、必要となる度に参照される。 The user touches an arbitrary point on the touch panel of the display unit 13 with a finger, a touch pen or the like, moves the contact position while keeping the contact, and ends the contact. By such a drag operation, the touch panel of the display unit 13 can acquire a touch point group between the contact start point and the contact end point. The touch point groups are numbered in the order of the acquired time series, and the touch point group vectors can be acquired by connecting the touch points in the order of the numbers. The vector of the touch point group corresponds to the movement vector of the touch operation. The touch point group acquired here is temporarily stored in the RAM of the control unit 11 and is referred to whenever necessary.
　図２は、表示部１３に表示される表示画像１３０の１例である。表示画像１３０は、少なくとも、ユーザーがタッチ操作を行って部品の設計図を描画するための描画用領域１３１と、ユーザーが行うタッチ操作の属性を選択するための属性選択用領域１３２と、見積りに必要な見積り情報２０１（図３参照）を設定するための見積り情報選択用領域１３３とを含む。 FIG. 2 is an example of the display image 130 displayed on the display unit 13. The display image 130 includes at least a drawing area 131 for a user to perform a touch operation to draw a part design drawing, an attribute selection area 132 for selecting an attribute of a touch operation performed by the user, and an estimate. And an estimation information selection area 133 for setting necessary estimation information 201 (see FIG. 3).
　ユーザーは、描画用領域１３１に対し、上述のタッチ操作を行うことによって、部品の設計図を描画することができる。なお、描画用領域１３１には、グリッド線が表示されていることが好ましい。これにより、ユーザーは、現在描写している部品の設計図のサイズを視覚的に把握することができる。さらには、タッチパネルに接触させた２本の指の離間距離を拡大または縮小させる等のタッチ操作によって、部品の設計図のサイズを容易に変更することができる。 The user can draw a design drawing of a part by performing the above touch operation on the drawing area 131. Note that grid lines are preferably displayed in the drawing area 131. As a result, the user can visually grasp the size of the design drawing of the part currently depicted. Furthermore, the size of the component blueprint can be easily changed by a touch operation such as enlarging or reducing the distance between two fingers in contact with the touch panel.
　また、属性選択用領域１３２の任意のアイコンをタッチすることにより、描画用領域１３１に対して行うタッチ操作の属性を選択することができる。ここでいう属性とは、直線を描画する、曲率半径が一定の曲線を描画する、所定の円や多角形等の図形を描画する、任意の線分または図形を削除するである。円や多角形等の図形は、部品の加工孔やネジ孔等を表すのに用いられる。 Further, by touching an arbitrary icon in the attribute selection area 132, an attribute of a touch operation performed on the drawing area 131 can be selected. The attribute here is to draw a straight line, draw a curve with a constant curvature radius, draw a figure such as a predetermined circle or polygon, or delete any line segment or figure. A figure such as a circle or a polygon is used to represent a machining hole or a screw hole of a part.
　また、見積り情報選択用領域１３３の任意のアイコンがタッチされると、表示部１３には、各種見積り情報２０１設定用の画面が表示される。ユーザーは、表示部１３に表示された各種見積り情報２０１設定用の画面をタッチすることにより、見積り情報２０１の設定を行うことができる。なお、図２の表示画像１３０では、見積り情報選択用領域１３３は、サイズ選択アイコン、材質選択アイコン、板厚選択アイコン、表面処理選択アイコン、個数選択アイコン、納期選択アイコン、作業工程選択アイコンから構成されているが、本発明はこれに限られない。見積り情報選択用領域１３３は、見積り情報を設定するための如何なるアイコンを含んでいてもよい。 Further, when an arbitrary icon in the estimated information selection area 133 is touched, a screen for setting various estimated information 201 is displayed on the display unit 13. The user can set the estimate information 201 by touching a screen for setting various estimate information 201 displayed on the display unit 13. In the display image 130 of FIG. 2, the estimation information selection area 133 is composed of a size selection icon, a material selection icon, a plate thickness selection icon, a surface treatment selection icon, a number selection icon, a delivery date selection icon, and a work process selection icon. However, the present invention is not limited to this. The estimated information selection area 133 may include any icon for setting estimated information.
　設計図生成部１４は、表示部１３が取得したタッチ点群に基づき、部品の設計図を生成する機能を有する。また、図４および図５を用いて後述するように、設計図生成部１４は、表示部１３が取得したタッチ点群のベクトルを取得し、該ベクトルの正規化および一体化により、部品の設計図を構成する線分を取得することができる。ここでいう線分とは、直線および曲率半径が一定の曲線を含む。 The design drawing generation unit 14 has a function of generating a design drawing of a part based on the touch point group acquired by the display unit 13. As will be described later with reference to FIGS. 4 and 5, the design drawing generation unit 14 acquires a touch point group vector acquired by the display unit 13, and normalizes and integrates the vector to design a part. A line segment constituting the figure can be acquired. The line segment here includes a straight line and a curve having a constant curvature radius.
　また、設計図生成部１４は、図６を用いて後述するように、生成した部品の設計図（２次元図面データ）から、３次元図面データを生成することができる。図６（ａ）は、設計図生成部１４が生成した部品の設計図が、曲げ加工断面図だった場合の３次元図面データ生成の例である。図６（ｂ）は、設計図生成部１４が生成した部品の設計図が、展開図だった場合の３次元図面データ生成の例である。図６（ｃ）は、設計図生成部１４が生成した部品の設計図が旋盤部品の断面図だった場合の３次元図面データ生成の例である。このように、設計図生成部１４が３次元図面データを生成することにより、３次元図面データから、部品の溶接部位、部品の容積・容量等の情報を取得することが可能となる。 Further, as will be described later with reference to FIG. 6, the design drawing generation unit 14 can generate three-dimensional drawing data from the generated design drawing (two-dimensional drawing data) of the part. FIG. 6A is an example of three-dimensional drawing data generation when the design drawing of the part generated by the design drawing generation unit 14 is a bending sectional view. FIG. 6B is an example of three-dimensional drawing data generation when the design drawing of the part generated by the design drawing generation unit 14 is a developed view. FIG. 6C shows an example of three-dimensional drawing data generation when the design drawing of the part generated by the design drawing generation unit 14 is a sectional view of a lathe part. As described above, the design drawing generation unit 14 generates the three-dimensional drawing data, so that it is possible to acquire information such as the welded part of the part, the volume / capacity of the part, etc. from the three-dimensional drawing data.
　見積り部１５は、設計図生成部１４が生成した部品の設計図に基づき、部品のコスト見積りを実行する機能を有する。見積り部１５は、部品の設計図、部品の周長、ネジ孔数、溶接面積等の図形情報２００（図３参照）、ユーザーによって設定された見積り情報２０１、見積り用パラメータＤＢ１２に記憶されているパラメータ等を参照して、部品のコスト見積りを実行する。 The estimation unit 15 has a function of executing cost estimation of a part based on the design drawing of the part generated by the design drawing generation unit 14. The estimation unit 15 is stored in the part design drawing, the part circumference, the number of screw holes, graphic information 200 such as the welding area (see FIG. 3), the estimation information 201 set by the user, and the estimation parameter DB 12. Referring to parameters etc., cost estimation of parts is executed.
　見積り済部品ＤＢ１６は、見積り部１５がコスト見積りした部品の設計図とコスト見積りを記憶するためのＤＢである。見積り済み部品ＤＢ１６に記憶されたデータは、データバス１８を介して、Ｉ／Ｏインターフェース１７に伝達され、フラッシュメモリ、プリンタ等の外部デバイス３０やネットワーク２０上のサーバー等のデバイスに出力される。 The estimated parts DB 16 is a DB for storing the design drawings and cost estimates of the parts estimated by the estimation unit 15. Data stored in the estimated component DB 16 is transmitted to the I / O interface 17 via the data bus 18 and output to an external device 30 such as a flash memory or a printer or a device such as a server on the network 20.
　Ｉ／Ｏインターフェース１７は、ネットワーク２０または外部デバイス３０とのインターフェースを取る機能を有する。Ｉ／Ｏインターフェース１７は、ネットワーク２０上のサーバー等、またはフラッシュメモリ、プリンタ等の外部デバイス３０とのデータの授受を行う。Ｉ／Ｏインターフェース１７により、例えば、ネットワーク２０、または外部デバイス３０からデータを受信して、見積り用パラメータＤＢ１２に記憶されているパラメータを更新、追加することが可能となる。そのため、例えば、新たな材料を用いて部品を製造したい場合、または新たな製造機械を用いて部品を製造したい場合等にも対応できる。 The I / O interface 17 has a function of interfacing with the network 20 or the external device 30. The I / O interface 17 exchanges data with a server on the network 20 or an external device 30 such as a flash memory or a printer. The I / O interface 17 can receive data from, for example, the network 20 or the external device 30, and update and add parameters stored in the estimation parameter DB 12. Therefore, for example, it is possible to cope with a case where a part is to be manufactured using a new material or a part is desired to be manufactured using a new manufacturing machine.
　上述した見積り装置１０の各部および各ＤＢは、データバス１８に接続されており、このデータバス１８を介して、各種データや各種指示の授受を行う。 Each unit and each DB of the estimation device 10 described above are connected to a data bus 18, and various data and various instructions are exchanged via the data bus 18.
　以上説明した見積り装置１０は、ＰＤＡ（Ｐｅｒｓｏｎａｌ　Ｄｉｇｉｔａｌ　Ａｓｓｉｓｔａｎｔ）、スマートフォン、タブレット型コンピュータ等のようなモバイル装置に備えられているのが好ましい。これにより、工場の製造現場、屋外等のマウスやキーボード等が通常備えられていない場所において、見積り装置１０を用いた部品の設計図生成とコスト見積りを実行することができる。 The estimation device 10 described above is preferably provided in a mobile device such as a PDA (Personal Digital Assistant), a smartphone, or a tablet computer. Thereby, design drawing generation of parts and cost estimation using the estimation device 10 can be executed in a factory manufacturing site, a place such as outdoors where a mouse or keyboard is not normally provided.
　次に、図３を参照して、見積り装置１０が行う処理（以下、単に「処理」という）について説明する。なお、図３において、実線の矢印は、処理の流れを表す。一方、破線の矢印は、データの流れを表す。 Next, with reference to FIG. 3, a process performed by the estimation apparatus 10 (hereinafter simply referred to as “process”) will be described. In FIG. 3, solid arrows indicate the flow of processing. On the other hand, broken arrows represent the flow of data.
　［１］図形入力工程ｓ１１０
　まず、ｓ１００において、制御部１１のＣＰＵからの指示によって、処理が開始される。次に、処理は、図形入力工程ｓ１１０に移行する。図形入力工程ｓ１１０では、上述したタッチパネル機能を有する表示部１３および設計図生成部１４を用いて、ユーザーのタッチ操作（入力）に基づき、部品の設計図を生成する。また、処理は、生成された設計図から、部品の周長、ネジ孔数、溶接面積等の情報を取得する。これらの情報は、図形情報２００として、制御部１１のＲＡＭに一時記憶され、後の工程で必要となる度に参照される。 [1] Figure input step s110
First, in s100, processing is started by an instruction from the CPU of the control unit 11. Next, the process proceeds to a figure input step s110. In the graphic input step s110, the design drawing of the part is generated based on the user's touch operation (input) using the display unit 13 and the design drawing generation unit 14 having the touch panel function described above. Further, the process acquires information such as the peripheral length of the component, the number of screw holes, and the welding area from the generated design drawing. These pieces of information are temporarily stored in the RAM of the control unit 11 as graphic information 200, and are referred to whenever they are required in a later process.
　図４は、図形入力工程ｓ１１０の処理を示すフローチャートである。まず、ｓ１１１において、図形入力工程ｓ１１０が開始される。次に、ｓ１１２において、表示部１３によって、タッチ点群が取得される。上述のように、このタッチ点群は、取得された時系列順に番号付けされている。次に、処理は、ｓ１１３に移行する。ｓ１１３において、ｓ１１２において取得したタッチ点群の重複点が削除される。このように、タッチ点群の重複点を削除することにより、後の工程で処理をするタッチ点群のベクトル数を減らすことができ、処理速度を向上させることができる。次に、処理は、ｓ１１４に移行する。ｓ１１４において、タッチ点群に付された番号順に、各タッチ点を結ぶことにより、タッチ点群のベクトルが取得される。次に、処理は、ｓ１１５に移行する。ｓ１１５において、取得したベクトルの正規化および一体化が実行される。なお、ｓ１１２からｓ１１６の処理は、設計図生成部１４を用いて実行される。 FIG. 4 is a flowchart showing the processing of the figure input step s110. First, in s111, a figure input step s110 is started. Next, in s112, the display unit 13 acquires a touch point group. As described above, the touch point groups are numbered in order of the acquired time series. Next, the process proceeds to s113. In s113, the overlapping points of the touch point group acquired in s112 are deleted. In this way, by deleting the overlapping points of the touch point group, the number of touch point group vectors to be processed in a later process can be reduced, and the processing speed can be improved. Next, the process proceeds to s114. In s114, the touch point group vectors are obtained by connecting the touch points in the order of the numbers assigned to the touch point groups. Next, the process proceeds to s115. In s115, normalization and integration of the acquired vector is performed. The processes from s112 to s116 are executed using the design drawing generation unit 14.
　図５は、ベクトルの正規化および一体化の処理を示すフローチャートである。まず、ｓ１１５１において、ｓ１１５が開始される。次に、処理は、ｓ１１５２に移行する。ｓ１１５２において、各ベクトルの垂直成分および水平成分の解析から、各ベクトルの角度が算出される。なお、図５中では上側を０°、右側を９０°、下側を１８０°、左側を２７０°として表現している。次に、処理は、ｓ１１５３に移行する。ｓ１１５３において、各ベクトルが正規化される。ここでいう正規化とは、各ベクトルに時系列順に付された番号と、算出した各ベクトルの角度に基づき、それぞれのベクトルを所定の方法で複数のカテゴリーに分類し、さらに、カテゴリー毎に各ベクトルの角度、始点位置、終点位置等を再設定することをいう。 FIG. 5 is a flowchart showing vector normalization and integration processing. First, in s1151, s115 is started. Next, the process proceeds to s1152. In s1152, the angle of each vector is calculated from the analysis of the vertical and horizontal components of each vector. In FIG. 5, the upper side is represented as 0 °, the right side is represented as 90 °, the lower side is represented as 180 °, and the left side is represented as 270 °. Next, the process proceeds to s1153. In s1153, each vector is normalized. The normalization here means that each vector is classified into a plurality of categories by a predetermined method based on the number assigned to each vector in chronological order and the calculated angle of each vector. This means resetting the vector angle, start point position, end point position, and the like.
　図５の例では、各ベクトルは、算出した各ベクトルの角度に基づき、３つのカテゴリー（９０°の角度を有するベクトルのカテゴリー１、１３５°の角度を有するベクトルのカテゴリー２、９０°の角度を有するベクトルのカテゴリー３）に分類されている。各カテゴリーでは、各ベクトルの角度が同一の値に再設定され、ベクトルの開始位置が次のベクトルの終点位置と一致するように再設定されている。また、あるカテゴリーの最後のベクトルの終了位置は、次のカテゴリーの最初のベクトルの開始位置と一致するようになっている。なお、この例では、ベクトルのカテゴリーは、４５°刻みのカテゴリーに分類されているが、本発明はこれに限られない。例えば、１５°刻みのカテゴリーに分類されてもよいし、もっと細かなまたは粗い刻みで分類を行ってもよい。 In the example of FIG. 5, each vector has three categories (category 1 of a vector having an angle of 90 °, category 2 of a vector having an angle of 135 °, and an angle of 90 ° based on the calculated angle of each vector. The vector is classified into category 3). In each category, the angle of each vector is reset to the same value, and the start position of the vector is reset to match the end position of the next vector. In addition, the end position of the last vector in a certain category matches the start position of the first vector in the next category. In this example, the vector category is classified into 45 ° increments, but the present invention is not limited to this. For example, it may be classified into categories of 15 ° increments, or classification may be performed with finer or coarser increments.
　次に、処理は、ｓ１１５４に移行する。ｓ１１５４において、正規化された各ベクトルは、一体化される。すなわち、各カテゴリーに含まれる複数のベクトルが、一本のベクトルにされる。ベクトルの一体化により、設計図を構成する線分を取得することができる。ここでは、線分として直線を取得する手順を説明したが、正規化と一体化のルールを変更することにより、曲率半径が一定の曲線（円弧）を取得してもよい。次に、処理は、ｓ１１５５に移行する。ｓ１１５５において、ｓ１１５は、終了する。 Next, the process proceeds to s1154. In s1154, each normalized vector is integrated. That is, a plurality of vectors included in each category are made into one vector. By integrating the vectors, it is possible to obtain line segments constituting the design drawing. Here, the procedure for acquiring a straight line as a line segment has been described, but a curve (arc) having a constant curvature radius may be acquired by changing the normalization and integration rules. Next, the process proceeds to s1155. In s1155, s115 ends.
　図４に戻って、処理は、ｓ１１６に移行する。ｓ１１６において、ｓ１１５で取得したベクトルに基づいて線分を取得することにより、部品の設計図（２次元図形データ）が生成される。次に、処理は、ｓ１１７に移行する。ｓ１１７において、図形入力工程ｓ１１０は、終了する。 Referring back to FIG. 4, the process proceeds to s116. In s116, a design drawing (two-dimensional graphic data) of a part is generated by acquiring a line segment based on the vector acquired in s115. Next, the process proceeds to s117. In s117, the figure input step s110 ends.

Next, the process proceeds to a three-dimensional drawing generation step s120. In the three-dimensional drawing generation step s120, as shown in FIG. 6, a three-dimensional drawing is generated based on the design drawing (two-dimensional graphic data) generated in the graphic input step s110. By generating a three-dimensional drawing, it is possible to acquire information such as the welded part of the part and the volume / capacity of the part. These pieces of information are temporarily stored in the RAM of the control unit 11 as graphic information 200, and are referred to whenever they are required in a later process.
　図６（ａ）は、生成した設計図（２次元図面データ）が、部品の曲げ加工断面図だった場合の３次元図面生成の手順を示している。生成した設計図に加え、部品の奥行長を設定することにより、部品の３次元図面を生成することができる。部品の奥行長は、ユーザーの表示部１３に対するタッチ操作から設定してもよいし、予め定められた値を設定してもよい。 FIG. 6A shows a procedure for generating a three-dimensional drawing when the generated design drawing (two-dimensional drawing data) is a bending sectional view of a part. In addition to the generated design drawing, a three-dimensional drawing of the part can be generated by setting the depth length of the part.

If a bending line exists in the generated design drawing, a three-dimensional drawing is generated based on the bending line.

When a rotation center line exists in the generated design drawing or when a rotation center line is designated by the user, a three-dimensional drawing is generated based on the rotation center line.

　次に、処理は、見積り情報設定工程ｓ１３０に移行する。見積り情報設定工程ｓ１３０では、表示部１３に対するユーザーのタッチ操作に基づき、見積り情報２０１が設定される。ユーザーによって、表示部１３の見積り情報選択用領域１３３を構成する任意のアイコンがタッチされると、表示部１３には、各種見積り情報２０１設定用の画面が表示される。ユーザーは、表示部１３に表示された、各種見積り情報２０１設定用の画面をタッチすることにより、見積り情報２０１の設定を行うことができる。 [3] Estimated information setting step s130
Next, the process proceeds to the estimation information setting step s130. In the estimate information setting step s130, the estimate information 201 is set based on the user's touch operation on the display unit 13. When the user touches an arbitrary icon constituting the estimation information selection area 133 of the display unit 13, a screen for setting various types of estimation information 201 is displayed on the display unit 13. The user can set the estimated information 201 by touching a screen for setting various estimated information 201 displayed on the display unit 13.
