Draft Workbench/zh

The Draft workbench allows to quickly draw simple 2D objects in the current document, and offers several tools to modify them afterwards. Some of these tools also work on all other FreeCAD objects, not only those created with the Draft workbench. It also provides a complete snapping system, and several utilities to manage objects and settings.

File formats
The Draft module provides FreeCAD with importers and exporters for the following file formats:


 * [[Image:Preferences-import-export.svg|32px]] Preference ... Import Export

 * SVG (as geometry): Imports and exports Scalable Vector Graphics files created with vector drawing applications
 * Open Cad format .OCA: Imports and exports OCA/GCAD files, a potentially new open CAD file format
 * Airfoil Data Format .DAT: Imports DAT files describing Airfoil profiles
