I'm pleased to announce the twenty-sixth 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 twenty-sixth release includes a few interface enhancements. More
of the menus can be activated from the keyboard, and stretch/move
operations now accept entry box values when performing either task.
A significant amount of work has been applied to the internal
routines used for storing the entities in a drawing, the result of
which required numerous changes throughout the code. The primary
change was adjusting the Quadtree search and storage routines to
handle the case where multiple instances of equivalent entities
are stored. In earlier releases of PythonCAD this scenario would
result in strange errors if it were to occur. As is always the case,
a large number of smaller bug fixes and code enhancements are also
present in this release.

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