We are the team!

( Actually, this is only part of our great team. Our lovely ladies are missing, as are our developers. This picture was taken at the LIGNA trade show 2019 and we rather like this shot as it shows how much fun we were having ? ).

Our Story

Beginning with MiniCAD, the predecessor to Vectorworks, interiorcad today is the market-leading interior design software in European markets with partners in Australia and New Zealand. Following in the footsteps of Vectorworks development, interiorcad takes advantage of the strong 3D modelling capabilities of Vectorworks, driven by the powerful Parasolid of Siemens PLM.
