I'm pleased to announce the thirtieth 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 newer. 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 thirtieth PythonCAD release addresses a number of issues that
appeared in the rewritten entity transfer code made available in the
previous release. By once again rewriting the entity transfer code,
the problems found in the last release have been fixed and additionally
a number of latent problems for handling undo/redo operations on
Dimension entities were addressed. In addition to the reworked
entity transfer code, a number of internal code enhancements appear
in this release. The use of the 'weakref' module has been eliminated,
and a number of other bug fixes and improvements have been applied
to the code.

A mailing list for the development and use of PythonCAD is available.
