FreeCAD is primarily a 3D modelling tool. There are times, however, when we must produce 2D drawings for documentation, contracts, permits, etc. The Technical Drawing workbench (TechDraw) is used to produce basic technical drawings based on the 3D model. Each drawing is a Page, and a Page contains many Views of Drawable Objects. The list of Drawable Objects includes Part::Features, PartDesign::Bodies, App::Part groups and Document Object groups.

Dimensions and hatched areas can be added to Views.


== Introduction ==
Note if your primary goal is the production of complex 2D drawings, you may wish to consider a dedicated tool such as LibreCad, QCad, TurboCad, etc.


The [[Image:Workbench_TechDraw.svg|24px]] [[TechDraw Workbench|TechDraw Workbench]] is used to produce basic technical drawings from 3D models created with another workbench such as [[Part Workbench|Part]], [[PartDesign Workbench|PartDesign]], or [[Arch Workbench|Arch]], or imported from other applications. Each drawing is a Page, which can contain various Views of drawable objects such as Part::Features, PartDesign::Bodies, App::Part groups, and Document Object groups. The resulting drawings can be used for things like documentation, manufacturing instructions, contracts, permits, etc.
{{Version|0.17}}

Dimensions, sections, hatched areas, annotations, and [[SVG|SVG]] symbols can be added to the page, which can be further exported to different formats like [[DXF|DXF]], [[SVG|SVG]], and [[PDF|PDF]].

If your primary goal is the production of complex 2D drawings and [[DXF|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 [https://en.wikipedia.org/wiki/LibreCAD LibreCAD] or [https://en.wikipedia.org/wiki/QCad QCad].

* TechDraw drawings and Python API are not interchangeable with the Drawing module. It is possible to convert Drawing Pages to TechDraw Pages using Python (moveViews.py). It is possible to have both TechDraw and Drawing Pages in the same FreeCAD document.
* There are minor differences in specifying Editable Texts in Templates compared to the Drawing module. See forum discussion [https://forum.freecadweb.org/viewtopic.php?f=3&t=24981&p=196271#p196271 here].

Introduction

The TechDraw Workbench is used to produce basic technical drawings from 3D models created with another workbench such as Part, PartDesign, or Arch, or imported from other applications. Each drawing is a Page, which can contain various Views of drawable objects such as Part::Features, PartDesign::Bodies, App::Part groups, and Document Object groups. The resulting drawings can be used for things like documentation, manufacturing instructions, contracts, permits, etc.

Dimensions, sections, hatched areas, annotations, and SVG symbols can be added to the page, which can be further exported to different formats like DXF, SVG, and PDF.

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.

Pages

These are tools for creating Page objects.

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:

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

Obsolete tools

  • Move View: moves a view and its dependents to a different page. Not available in version 0.22 and above.

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.
