Founded in Australia by Lee Gregory and Alan Gray, the first version of 12d Model was released in 1991, Both visionaries had worked in the industry for many years and found that the solutions on offer simply were not the most user friendly and that a true customer focus was lacking.

Today, we are proud to say that 12d Model is used in over 65 countries worldwide and our licenses are still growing. It is a solution that can be used by small businesses and individual consultants, through to large organisations.

In more recent years, we’ve introduced 12d Synergy – the streamlined data management, project collaboration and worksharing solution for your architectural, engineering and construction office.
