简介

在FreeCAD中,词"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. Start with an already built 3D model, created with, for example, the PartDesign Workbench. In fact, any object that has a Shape, including 2D objects, will work.
  2. Switch to the TechDraw Workbench.
  3. Press TechDraw PageDefault or TechDraw PageTemplate to create a Page.
  4. Select the existing model, and then press TechDraw View or TechDraw ProjectionGroup.
  5. A 2D projection on the page will be created. You may now adjust its properties, like 数据Scale, 数据Rotation, and 数据Direction.
  6. When the drawing is ready, you can press TechDraw ExportPageSVG, TechDraw ExportPageDXF, or use Std Export, to export the page to SVG, DXF, or PDF formats for further use in another software, or for printing.

Notes

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.
