Archicad, developed by Graphisoft, is a CAD software tailored for architects and building professionals, offering Building Information Modeling (BIM) capabilities for efficient architectural design and documentation.
Autodesk's AutoCAD is a general-purpose CAD software utilized broadly in engineering.
DataCAD, primarily for architectural design, is not a Graphisoft product.
CYCAS is a CAD software predominantly for civil and structural engineering.
Thus, Archicad, the CAD software from Graphisoft, is the appropriate choice.
