ArchiCAD is a computer-aided design and building information modeling (BIM) software from a software company called Graphisoft. The software is suited for architecture and engineering projects. You can use it to draft 2D and 3D models, architectural renderings, and technical drawings. Architects, drafters, and engineers can utilize ArchiCAD to plan both the aesthetics and technical aspects of construction projects. ArchiCAD also has building information modeling capabilities which allow users to store data and structural information within the model. This additional data helps with the design and building process. Third-party developers have created add-ons that drafters can use with ArchiCAD.
