ArchiCAD is an integrated three-dimensional CAD package for architectural design and construction documentation.

ArchiCAD's complete integration provides the ability to process interlinked '3D' modeling and '2D' drawing information within the same working database. Changes in the floor plan or in section/elevation views automatically update the building model and all related documents. ArchiCAD fully renders perspectives, 3D sections and animations including shadow casting with optional light sources and backgrounds. Accurate sun studies can be automatically generated for any location, date and time. ArchiCAD's direct support of the QuickTime VR virtual reality technology offers an interactive method to explore digital architectural environments
