简介

TechDraw 工作台被用来从来自其他工作台(比如Part, PartDesign, 或 Arch)创建的 或 从其他应用程序导入的3D模型生成基本的技术图纸。每张图纸是一页,可以包含可绘制对象(比如Part::Features, PartDesign::Bodies, App::Part groups 和文档对象组)的各种视图。得到的图纸可被用于诸如文档、制造说明、合同、许可等。

尺寸标注、剖面、填充区、注解和SVG符号都可以加到图纸中,而这些又可以进一步导出到不同的格式,如 DXF, SVG, PDF.

如果你的主要目标是产生复杂的2D图纸和DXF文件,并且不需要3D建模,FreeCAD可能不是正确的选择。你应该考虑一个用于绘制工程草图的专门的软件,如 LibreCADQCad.

页面

下面是创建页面对象的工具

Views

These are tools for creating View objects.

  • Insert Section Views:

Stacking

These are tools for changing the stacking order which controls the apparent depth of views on a page.

  • Adjust Stacking Order:

Clips

These are tools to create and manage Clip objects (clipped views).

Decorations

These are tools to decorate pages or views:

Dimensions

These are tools for creating and working with Dimension objects.

Linear dimensions can be based on two points, on one line, or on two lines.

  • Insert Extent Dimensions:

Annotations

The annotation tools are for "marking up" a drawing with additional information.

  • Add Cosmetic Vertices:
  • Add Centerlines:

Extensions

These are tools to improve your TechDraw drawings.

Attributes and modifications

  • Change Length of Cosmetic Lines or Centerlines:
  • Align Dimensions:
  • Evenly Space Dimensions:

Centerlines and threading

  • Add Centerlines:
  • Add Cosmetic Threads:
  • Add Vertexes:
  • Add Cosmetic Circles or Arcs:
  • Add Cosmetic Parallel or Perpendicular Lines:

Dimensions

  • Create Chain Dimensions:
  • Create Coordinate Dimensions:
  • Create Chamfer Dimensions:
  • Insert Prefix:
  • Change Decimal Places:

Export

These are tools for exporting pages to other applications.

Additional features

Preferences

  • Preferences: preferences for the default values of the drawing page such as projection angle, colors, text sizes, and line styles.

Scripting

The TechDraw tools can be used in macros and from the Python console. For more information see:

Limitations

  • Do not cut, copy and paste TechDraw objects in the Tree view as this generally does not work out well.
  • Do not drag TechDraw objects in the Tree view with the mouse.

Tutorials

A "few" added lines of code result in a tool like the Macro TemplateHelper.
