Drawing/zh-cn

简介

在FreeCAD中，"图样"通常指一个3D 模型的二维投影。这个3D模型通常是用TechDraw 工作台创建的

用法

1. 从一个已经构建的3D模型开始，例如，使用PartDesign Workbench创建的模型。 事实上，模型可以是任何具有Shape的对象(包括2D对象)。
2. 切换到 TechDraw Workbench.
3. 点击 TechDraw PageDefault 或 TechDraw PageTemplate 创建一个页面.
4. 选择已有的模型,然后点击 TechDraw View 或 TechDraw ProjectionGroup.
5. 在新创建的页面上会有一个2D投影被创建. 现在你可以调整他的属性, 比如数据Scale, 数据Rotation, 还有数据Direction.
6. 图样准备好之后, 你可以点按 TechDraw ExportPageSVG, TechDraw ExportPageDXF, 或使用 Std Export, 将页面导出到 SVG, DXF, or PDF 格式以备将来用在其他软件中, 或用于打印.

说明

In informal usage, a "Drawing" may be any geometrical figure that is visible in the 3D view, and thus its concept may be confused with that of "Body", "Part", or "model".

However, when more precision is required, the distinction must be made.

• A "Body" (PartDesign Body) is an object derived from a Part Feature (Part::Feature class), created with the PartDesign Workbench.
• A "Part" (App Part) is used to group several "Bodies" to form an assembly.
• A "Drawing" is a 2D projection of a "Body" or a "Part".
