CADEMIA

As a solution, a new platform for geometry-oriented AEC applications has been developed at Bauhaus University Weimar: CADEMIA. While CADEMIA was originally written for teaching and research purposes it is now available as open source software for the practitioner. A long time experience in the development of these systems in the building industry forms the basis on which CADEMIA is built.

The modular design principle of CADEMIA offers lots of possibilities to integrate other functionalities. Due to this flexibility CADEMIA can easily be customized to fit individual needs. CADEMIA is programmed in Java and is therefore platform independent. This way it serves as an inexpensive alternative to proprietary CAD software. The simplicity of the user interface and the easy installation allow CADEMIA to be used both by experts and occasional users. CADEMIA runs on all relevant platforms: Windows, Mac, Linux. CADEMIA is a top quality product of free software licensed under the GPL. Applications of arbitrary complexity can be efficiently implemented as Plug-Ins.
