[ANNOUNCE] Twentieth release of PythonCAD now available

["Art Haas" <ahaas airmail net>]

Hi.

I'm pleased to announce the twentieth 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 PythonCAD 
interfaces will depend on the availability of a Python module for that
particular interface and developer interest and action.

The twentieth release of PythonCAD improves the undo/redo abilities
of the program by making layer creation and deletion actions that
can be undone or redone. Also, the addition and removal of chamfers
and fillets is now an undoable and redoable action. The code for
managing undo/redo operations has been improved, and various bug
fixes for these actions have been applied. Another improvement in
this release is a reworked set of file saving operations. The code
for saving a file onto disk has been made more robust by adding
additional error checks and by ensuring the new version of a file
is stored successfully prior to replacing the existing copy. A
good number of bug fixes and code improvements are included in
this release as well.

PythonCAD is now two years old! The first public release was on December
21, 2002. Celebrate PythonCAD's second birthday by downloading and
installing the twentieth release!
