It has been about a decade and a half since 3D scanners burst onto the scene, fuelling speculation about whether we would see an end, or at least a big diminishing, to the type of blank-screen modelling provided by CAD programs.
These days we know better: 3D scanning and processing has evolved into a complementary approach to traditional CAD modeling.
Although 3D scanning and processing, or reverse engineering if you like, has not exploded like its early proponents might have hoped, it has progressed steadily, even within years of almost negligible CAD growth.
Recent years have not brought any revolutions, but there has been an orderly march forward indicative of a mature market – lower hardware costs or greater capabilities at the same cost, more entrants in the field, better portability, and greater ease of use.
