LOD is more than just an acronym for levels of detail; it's the methodology that precisely defines the degree of maturity of a BIM (Building Information Modeling) model. It is a common language that makes it easier for all stakeholders to understand and manage a project. At various stages of the construction process, from the conceptual phase to physical completion, LOD plays a key role. We tell you all about it.
What is LOD?
LOD, an acronym for Level of Detail, has been defined by the BIM Forum. The term refers to the segmentation of a
3D model
the LOD challenge? To standardize the way in which the geometric information and attributes of a BIM model take shape throughout the design and construction stages of a project.
Are Level of Information and Level of Detail different?
The LOD does not denote a degree of maturity; it responds to a need to
precision
. A low LOD is not to be confused with a lack of information. In fact, the term Level of Information (LOI) is commonly used. It should be noted, however, that LOI is not intended to replace Level of Detail
non-graphical information attached to 3D objects.
By combining LOD and LOI, we obtain the so-called " Level Of Development ". Abbreviated "LOD's", it refers to both the geometric and informative levels of detail in the
