Draft Workbench/ja

Draftワークベンチのアイコン

概要

製図ワークベンチを使うと現在のドキュメントにシンプルな2Dオブジェクトを手軽に描くことができます。また描いた後でそれらを変更するためのツールもいくつか用意されています。ツールの一部は製図ワークベンチで作成したものだけでなく他のFreeCADオブジェクト全てに対して使用することができます。また完璧に動作するスナップシステムやオブジェクトと設定を管理するためのいくつかのユーティリティも提供されています。

Draft objects can be used for general drafting, similar to what can be done with Inkscape or AutoCAD. But they can also form the base for the creation of 3D objects in other workbenches. A Draft Wire may define the path of an Arch Wall, a Draft Polygon can be extruded with Part Extrude, etc. Many of the Draft modifier tools can be applied to 2D and 3D objects created with other workbenches as well. You can, for example, move a Sketch or create a Draft OrthoArray from a Part object.

The Draft Workbench also provides tools to define a working plane, a grid, and a snapping system to precisely control the position of geometry.

If your primary goal is the production of complex 2D drawings and DXF files, and you don't need 3D modelling, FreeCAD may not be the right choice for you. You may wish to consider a dedicated software program for technical drafting instead, such as LibreCAD or QCad.

The image shows the grid aligned with the XY plane.
On the left, in white, several planar objects.
On the right a non-planar Draft Wire used as the Path Object of a Draft PathArray.

Drafting

  • Arc: creates a circular arc from a center, a radius, a start angle and an aperture angle.
  • Arc by 3 points: creates a circular arc from three points that define its circumference.

Annotation

Modification

  • Array: creates an orthogonal array from a selected object. It can optionally create a Link array.
  • Polar array: creates an array from a selected object by placing copies along a circumference. It can optionally create a Link array.
  • Circular array: creates an array from a selected object by placing copies along concentric circumferences. It can optionally create a Link array.
  • Path array: creates an array from a selected object by placing copies along a path.
  • Point array: creates an array from a selected object by placing copies at the points from a point compound.

Draft Tray

The Draft Tray allows selecting the working plane, defining style settings, toggling construction mode, and specifying the active layer or group.

Draft annotation scale widget

With the Draft annotation scale widget the Draft annotation scale can be specified.

Draft snap widget

The Draft snap widget can be used as an alternative for the Draft snap toolbar.

Draft snap toolbar

The Draft snap toolbar allows selecting the active snap options. The buttons belonging to active options stay depressed. For general information about snapping see: Draft Snap.

ユーティリティーツール

Additional tools

右クリックのコンテキストメニューから利用可能な追加ツールです。選択されているオブジェクトに依存して変わります。

追加機能

  • スナッピング: 既存オブジェクトの特定位置に新しい点を配置できます
  • 拘束: 既存の点に対して相対的な水平位置、垂直位置を指定して新しい点を配置できます
  • Working plane: Allows you to define a plane in the 3D space, where next operations will take place

Tree view context menu

For a Draft Layer these additional options are available:

Text options

For a Draft Text and a Draft Label that contains one or more hyperlinks, to a local or remote file or an URL, this additional option is available:

Wire options

For a Draft Line and a Draft Wire this additional option is available:

環境設定

  • 製図モジュールには専用の環境設定ドラフトワークベンチで利用可能な設定。

ファイル形式

製図モジュールによってFreeCADは以下のファイル形式をインポート、エクスポートできるようになっています。

Unit tests

See also: Test Workbench.

To run the unit tests of the workbench execute the following from the operating system terminal:

freecad -t TestDraft

スクリプト処理

製図モジュール機能には完全な製図用APIがあり、スクリプトやマクロからその機能を使用することができます

The workbench includes a module to create samples of all objects in a new document.

Use this to test that all objects are produced correctly:

import drafttests.draft_test_objects as dto
doc = dto.create_test_file()

Inspecting the code of this module can help to understand the programming interface.
