While the abandoned Geometry Constructions tool for Inkscape still fails to find a new developer, Euclide sees development activity again.

In a nutshell, Euclide is a free crossplatform application tailored for geometry constructions.

The application provides quite a lot of ways to draw various geometric primitives and measure them. You can also change styles and use layers to separate parts of constructions. There's over a dozen of transforms you can apply to your constructions too.

Since developement resumed in early September, Euclide got the following new features:

• Vertical Line and Horizontal Line tools;
• union and intersection of polygons;
• complement of a domain;
• rectangle by two corners.

Euclide is written in Java, so it runs virtually anywhere. You can download a ready to use package as well as source code here.

Sadly, unlike AlDraw, a newer attempt at the same feature set, Euclide doesn't yet provide an SVG exporter. Hopefully this will be addressed in the future.
