I'm pleased to announce the twenty-ninth 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-ninth release of PythonCAD contains various improvements
to the internal entity creation and manipulation code. The routines
for transferring entities between layers has been reworked, as have
the routines for deleting entities. This code rework flushed out
a number of bugs and sub-optimal code issues which have been resolved.
The code for creating and modifying Dimension entities was both
simplified by removing redundant arguments to various methods and
some missing undo/redo abilities were added as well. In addition to
internal code improvements, the ability to toggle RadialDimension
entities to display diameter values and the ability to invert an
AngularDimension entity have been added to the interface. Lastly,
a variety of miscellaneous bug fixes and code improvements are
present in this release.
