General description:
The Draft module is a FreeCAD module for drawing/editing 2D entities.
The aim is to give FreeCAD basic 2D-CAD capabilities (similar
to Autocad and other similar software). This modules is made to be run
inside FreeCAD and needs the PyQt4 and pivy modules available.
User manual:
http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=2d_Drafting_Module
How it works / how to extend:
This module is written entirely in python. If you know a bit of python
language, you are welcome to modify this module or to help us to improve it.
Suggestions are also welcome on the FreeCAD discussion forum.
If you want to have a look at the code, here is a general explanation. The
Draft module is divided in several files:
- Draft.py: Hosts the functions that are useful for scripting outside of
the Draft module, it is the "Draft API"
- DraftGui.py: Creates and manages the special Draft toolbar
- DraftTools.py: Contains the user tools of the Draft module (the commands
from the Draft menu), and a couple of helpers such as the "Trackers"
(temporary geometry used while drawing)
- DraftVecUtils.py: a vector math library, contains functions that are not
implemented in the standard FreeCAD vector
- DraftGeomUtils.py: a library of misc functions to manipulate shapes.
The Draft.py contains everything to create geometry in the scene. You
should start there if you intend to modify something. Then, the DraftTools
are where the FreeCAD commands are defined, while in DraftGui.py
you have the ui part, ie. the draft command bar. Both DraftTools and
DraftGui are loaded at module init by InitGui.py, which is called directly by FreeCAD.
The tools all have an Activated() function, which is called by FreeCAD when the
corresponding FreeCAD command is invoked. Most tools then create the trackers they
will need during operation, then place a callback mechanism, which will detect
user input and do the necessary cad operations. They also send commands to the
command bar, which will display the appropriate controls. While the scene event
callback watches mouse events, the keyboard is being watched by the command bar.
