Draft Workbench/ja
Introduction
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.
