CIM stands for “City Information Modeling,” the concept being similar to how BIM stands for “Building Information Modeling.” However, while BIM is very much alive and well in the AEC industry, that doesn’t seem to have happened with CIM — the term hasn’t really taken off.

These are some of the questions explored in this article.
