2D BIM describes a dimension which refers to the level of information stored alongside or integrated within a modelling environment. 2D BIM is the most basic digital geometric model on the X and a Y axis with associated further information. Today it is not industry standard, often not considered as a BIM tool but maybe referred to in the context of models of increasing complexity as the first step before 3D BIM, 4D BIM, 5D BIM, 6D BIM and 7D BIM. There are also potentially 8D, 9D, 10D and 11D, though these are not generally formalised or standardised and as such recognised as known dimensions.

For further information visit BIM dimensions, maturity and levels of development and level 2 BIM.
