Introduction

The Workbench TechDraw.svg 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.

TechDraw was officially included in FreeCAD starting with version 0.17; it is intended to replace the unsupported Drawing Workbench. Both workbenches are still provided in v0.17, but the Drawing Workbench may be removed in future releases. To keep up with TechDraw plans and developments, visit the TechDraw Roadmap.

FreeCAD is primarily a 3D modelling application, and thus doesn't have many 2D drawing tools, which are mostly included in the Draft and Sketcher Workbenches. If your primary goal is the production of complex 2D drawings and DXF files, and you don't need 3D modelling, you may wish to consider a dedicated software program for technical drafting such as LibreCAD, QCad, TurboCad, and others.

TechDraw Workbench Example.png

Pages

These are tools for creating Page objects.

Views

These are tools for creating View objects.

Clips

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

  • TechDraw Dimension Radius.svg New Radius: adds a radius dimension to a circle or circular arc.
  • TechDraw Dimension Diameter.svg New Diameter: adds a diameter dimension to a circle or a circular arc.
  • TechDraw Dimension Angle.svg New Angle: adds an angle dimension between two straight edges.
  • TechDraw Dimension Angle3Pt.svg New Angle3Pt: adds an angle dimension using three vertices.
  • TechDraw Dimension Link.svg New Links: links an existing dimension to the 3D geometry.

Import/Export

These are tools for exporting pages to other applications.

Decorations

These are tools to decorate pages or views:

Annotation

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

Additional features

  • Line Groups: to control the appearance of various types of lines.
  • Templates: the default templates defined for the drawing pages.
  • Hatching: explanation of the different hatching techniques.

Preferences

  • Preferences-techdraw.svg 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 by using two APIs.

Limitations

  • TechDraw drawings and its API are not interchangeable with the Drawing Workbench and its API. It is possible to convert Drawing Pages to TechDraw Pages using a Python script (moveViews.py).
  • It is possible to have both TechDraw and Drawing Pages in the same FreeCAD document, as each page is completely independent from each other.
  • There are minor differences in specifying editable texts in SVG templates compared to the Drawing module. In TechDraw the scaling of the SVG document affects the position of the editable text fields. See the forum discussion TechDraw templates scale for more details.
  • Do not cut, copy and paste TechDraw objects in the tree view as this generally does not work out well.
