Drawing Module/ja

ドローイングモジュールを使うと3D作業物を紙の上に移すことができます. つまりモデルのビューを2Dウィンドウに表示し、図面にそのウィンドウを挿入するということです. 例えば枠線、タイトル、ロゴマークが入ったシートに挿入し、最終的にそのシートを印刷することができます. ドローイングモジュールは現在も製作中で多かれ少なかれ技術面でのテスト段階にあります！

GUIツール
2D図面を作成、設定、エキスポートするためのツールです.


 * [[Image:Drawing_New.png|32px]] スケーラブルベクターグラフィックを開く: SVGファイルとして保存されている図面を開きます


 * [[Image:Drawing_Landscape_A3.png|32px]] A3図面の新規作成: FreeCADのデフォルトのA3テンプレートから新しい図面を作成します


 * [[Image:Drawing_View.png|32px]] ビューの挿入: アクティブな図面上に選択されたオブジェクトのビューを挿入します


 * [[Image:Drawing_Annotation.png|32px]] Annotation: Adds an annotation to the current drawing sheet


 * [[Image:Drawing_Clip.png|32px]] Clip: Adds a clip group to the current drawing sheet


 * [[Image:Drawing_Openbrowser.png|32px]] Open Browser: Opens a preview of the current sheet in the browser


 * [[Image:Drawing_Orthoviews.png|32px]] Ortho Views: Automatically creates orthographic views of an object on the current drawing sheet


 * [[Image:Drawing_Symbol.png|32px]] Symbol: Adds the contents of a SVG file as a symbol on the current drawing sheet


 * [[Image:Drawing_DraftView.png|32px]] Draft View: Inserts a special Draft view of the selected object in the current drawing sheet


 * [[Image:Drawing_SpreadsheetView.png|32px]] Spreadsheet View: Inserts a view of a selected spreadsheet in the current drawing sheet


 * [[Image:Drawing_Save.png|32px]] 図面の保存: 現在の図面をSVGファイルとして保存します


 * Project Shape: Creates a projection of the selected object (Source) in the 3D view.

Note The Draft View tool is used mainly to place Draft objects on paper. It has a couple of extra capabilities over the standard Drawing tools, and supports specific objects like Draft dimensions.



この画像を見るとドローイングモジュールの主要なコンセプトが見て取れます. ドキュメントには図面に引用したい形状オブジェクト（Schenkel）が入っています. さらに"Page"が作成されています. ページはテンプレートに基づいてインスタンス化されます. 今回のケースでは"A3_Landscape"テンプレートです. テンプレートにはSVGドキュメントであなたが普段使っているページ枠、ロゴ、標準のプレゼンテーション資料規格を使うことができます.

このページには複数のビューを挿入することができます. 各ビューはページ上での位置（X、Yプロパティ）、拡大率（スケールプロパティ）などをはじめとした属性情報を持っています. ページ、ビュー、参照しているオブジェクトが変化するとそのたびにページが再生成され、ページの表示が更新されます.

スクリプト処理
今のところエンドユーザー用の（GUI）ワークフローは非常に限定されたものしか用意されていません. APIはもっと充実しています. 以下ではドローイングモジュールのスクリプト処理用APIをどう使うかの例を挙げていきます.

Here a script that can easily fill the Macro_CartoucheFC leaf FreeCAD A3_Landscape.

簡単な例
まずはパートモジュールとドローイングモジュールが必要です.

小さなサンプルパーツを作成します.

投影させます. G0はシャープな輪郭線、G1は連続線を意味します.

Everything was projected on the Z-plane:

異なる投影ベクトル.

SVGに投影.

パラメトリックな方法
物体を作成します.

Pageオブジェクトを挿入し、テンプレートを代入

Create a view on the "Shape" object, define the position and scale and assign it to a Page

Create a second view on the same object but this time the view will be rotated by 90 degrees.

Create a third view on the same object but with an isometric view direction. The hidden lines are activated too.

Change something and update. The update process changes the view and the page.

Accessing the bits and pieces
Get the SVG fragment of a single view

Get the whole result page (it's a file in the document's temporary directory, only read permission)

Important: free the file!

Insert a view with your own content:

That leads to the following result:



General Dimensioning and Tolerancing
Drawing dimensions an tolerances are still under development but you can get some basic functionality with a bit of work.

First you need to get the gdtsvg python module from here (WARNING: This could be broken at any time!):

https://github.com/jcc242/FreeCAD

To get a feature control frame, try out the following:

Here is a good breakdown of the contents of a feature control frame: http://www.cadblog.net/adding-geometric-tolerances.htm

The parameters to pass to control frame are:
 * 1) X-coordinate in SVG-coordinate system (type string)
 * 2) Y-coordinate in SVG-coordinate system (type string)
 * 3) The desired geometric characteristic symbol (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 4) The tolerance (type string)
 * 5) (optional) The diameter symbol (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 6) (optional) The condition modifying material (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 7) (optional) The first datum (type string)
 * 8) (optional) The first datum's modifying condition (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 9) (optional) The second datum (type string)
 * 10) (optional) The second datum's modifying condition (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 11) (optional) The third datum (type string)
 * 12) (optional) The third datum's material condition (tuple, svg string as first, width of symbol as second, height of symbol as third)

The ControlFrame function returns a type containing (svg string, overall width of control frame, overall height of control frame)'''

To get a dimension, try out the following:

Inputs for linear dimension are:
 * 1) point1, an (x,y) tuple with svg-coordinates, this is one of the points you would like to dimension between
 * 2) point2, an (x,y) tuple with svg-coordinates, this is the second point you would like to dimension between
 * 3) textpoint, an (x,y) tuple of svg-coordinates, this is where the text of your dimension will be
 * 4) dimensiontext, a string containing the text you want the dimension to say
 * 5) linestyle, a string containing svg (i.e. css) styles, using the getStyle function to retrieve a preset string, for styling the how the lines look
 * 6) arrowstyle, a string containing svg (i.e. css) styles, using the getStyle function to retrieve a preset string, for styling how the arrows look
 * 7) textstyle, a string containing svg (i.e. css) styles, using the getStyle function to retrieve a preset string, for styling how the text looks

With those two, you can proceed as above for displaying them on the drawing page. This module is very buggy and can be broken at any given moment, bug reports are welcome on the github page for now, or contact jcc242 on the forums if you post a bug somewhere else.

Templates
FreeCAD comes bundled with a set of default templates, but you can find more on the Drawing templates page.

Extending the Drawing Module
Some notes on the programming side of the drawing module will be added to the Drawing Documentation page. This is to help quickly understand how the drawing module works, enabling programmers to rapidly start programming for it.
