Nemetschek provides computer-aided design (CAD) software to architects, engineers, contractors, and real estate managers. The company's Allplan software suite is used to design, build, and manage buildings such as sports arenas, train stations, airports, and apartments. In 2000 Nemetschek acquired a US company, Diehl Graphsoft, and made it into Nemetschek North America, offering VectorWorks (design) and RenderWorks (presentation) software. In 2002 the company merged its German subsidiaries into two new ventures, Nemetschek Bausoftware and Nemetschek CREM Solutions.
