Computer-aided architectural design
Computer-aided architectural design ( CAAD for short ) is computer-aided design for architects .
Since the 1960s, attempts have been made to save time when modeling spatial structures with the help of suitable software. The use of ordinary CAD programs was often associated with difficulties, as they did not have all the necessary planning and design tools, so that a stand-alone CAD application developed for the architectural sector.
Based on the CAAD files, models can be created using CAAM .
features
The CAAD software has a database with geometric shapes that are linked to certain properties. In contrast to standard CAD software, the architect can access building-specific objects and data. The software knows all the components including their properties and supports creative use during the design phase.
The boundaries between CAAD software and other computer-aided drawing software cannot always be clearly drawn. Classic animation programs such as 3ds Max are also used to represent and present or animate designs by architects. The application of the finite element method may be part of a computer-based design software that is used very rarely in the draft determination and is only used for mathematical proofs of building structures.
construction
The structure of typical CAAD software usually consists of at least two levels. The first level is used to calculate and display the geometric definition of the design. This inner representation can, depending on the software, consist of 2D or 3D models. At this level, the plans are linked with other data such as labels, dimensions and material properties. The results of this process can be output as plans, floor plans, sections, views and, in the case of 3D models, in spatial representations.
On a second level, these aggregated, i.e. provided with additional information, geometric bodies are analyzed using database operations. This allows meta information to be created in list form, such as area lists and lists for determining quantities, parts lists, and sometimes construction schedules. Since the computer can achieve a high computing power and can therefore also calculate and display technically unworkable constructions and arrangements, this level limits and monitors the selection and scope and pays attention to the functionality (technical feasibility) of the design.
Another name for construction software is AEC (Architecture, Engineering, Construction). Often, additional or better developed modules for construction, structural calculation and tendering of components are included. The boundaries to the CAAD are fluid.
