I'm pleased to announce the fifteenth development release of PythonCAD,
a CAD package for open-source software users. As the name implies,
PythonCAD is written entirely in Python. The goal of this project is
to create a fully scriptable drafting program that will match and eventually
exceed features found in commercial CAD software. PythonCAD is released
under the GNU Public License (GPL).

PythonCAD requires Python 2.2 or Python 2.3. The interface is GTK 2.0
based, and uses the PyGTK module for interfacing to GTK. The design of
PythonCAD is built around the idea of separating the interface
from the back end as much as possible. By doing this, it is hoped
that both GNOME and KDE interfaces can be added to PythonCAD through
usage of the appropriate Python module. Addition of other interfaces
will depend on the availability of a Python module for that particular
interface and developer interest and action.

The fifteenth release of PythonCAD offers users on Mac OS X a native,
Cocoa based interface utilizing the Python/Objective-C bridge. The
Python/Objective-C code is available at http://pyobjc.sf.net/. A nice
side benefit from the development of the Cocoa code was the exposure
of various bugs and design issues in the interface neutral code. Bugs
exposed by this work have been fixed, and several design improvements
are now in the code thanks to this work. The Cocoa interface code is
contributed by David Haas, and I thank him greatly for his work.

This release includes several more undo/redo improvements. The addition
and removal of points on a polyline can now be undone or redone, and
assorted other editing operations have improved undo/redo handling
as well. A variety of bug fixes have also been added in this release.
Small bugs regarding entity searching, arc boundaries, layer addition
and removal, and entity storage have been fixed. A few code improvements
appear in this release also.
