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.
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.

These are tools for exporting pages to other applications.

The TechDraw tools can be used in macros and from the Python console by using two APIs.
- 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.
- Do not drag TechDraw objects in the Tree view with the mouse.
