Bancada de trabalho TechDraw
Introdução
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.
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.

Extension Package
The Extension Package includes many useful tools to improve your TechDraw drawings.
Some of these tools have yet to be released.
- CircleCenterLines: adds center lines to circles and arcs. introduced in version 0.20
- ThreadHoleSide: adds a symbolic thread to the side view of a hole. introduced in version 0.20
- ThreadHoleBottom: adds symbolic threads to the bottom view of holes. introduced in version 0.20
- ThreadBoltSide: adds a symbolic thread to the side view of a bolt. introduced in version 0.20
- ThreadBoltBottom: adds symbolic threads to the bottom view of bolts. introduced in version 0.20
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.
- Geometric dimensioning and tolerancing: explanation on how to achieve geometric dimensioning and tolerancing.
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 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.
- Threads are not implemented. A possible workaround is to use a diameter dimension and put a suitable text into the "Format Spec" property, e.g. "M4x15"
- Do not cut, copy and paste TechDraw objects in the tree view as this generally does not work out well.
