Univ. of Ljubljana, FGG, Chair of Construction Informatics Create process Create. Information is created, most likely by processing the input. Typical approaches to information creation are analysis of the input, synthesis of information input, and through human input and intervention, for example, in drafting and 3D modelling. Create.
