The development of the computer industry has largely contributed to significant progress in design. For several decades, computers have supported designers worldwide. The current computer-aided design systems are a basic tool in any engineering project, from calculations through to complex graphic design. There are many computer-aided programmes designed for the construction industry on the market. So far, the most popular has been CAD i.e. Computer Aided Design, which has supported construction industry designers for years. However, the market in Poland and worldwide is currently being revolutionised by BIM technology. This tool is already shaping the future of construction. The technology not only works well in designing and implementing investments, but thanks to the virtual mapping of an object it also results in efficient management and maintenance. The paper presents the features of CAD and BIM technologies and their influence on modern design-using computer techniques.
