StaticsPad

StaticsPad is a program for simple structural design using the discipline of graphic statics. It supports the textbook Form and Forces: Designing Efficient, Expressive Structures by Edward Allen and Waclaw Zalewski.

The software is open-source and freely available. It is currently not fully functional, and it is not yet built for download on any platform other than Windows, although it is written in cross-platform C++ with Qt.
