What is a Level Of Detail (LOD)?

The level of detail, better known by the acronym LOD (Level Of Detail), corresponds to the geometric precision of a digital model.

What is the purpose of LODs?

Depending on the specificities of his project and the associated specifications, it will be a question of quantifying the information necessary for his use of the model. An LOD level can then be associated with this minimum level of information and provide guidelines for obtaining a BIM modeling consistent with his project.

To summarize, correctly defining the LOD of your digital model will allow you to:

• Remove ambiguities in deliverables with their modeling provider;
• Frame the modeling phase with precise specifications;
• Optimize modeling costs according to your needs.

Optimizing the LOD of a digital model

An entire digital model does not necessarily have to offer the same level of detail. On the contrary!

Par exemple, un bureau d’études fluides pourrait tout à fait exploiter une maquette composée d’une structure architecturale au LOD 200 et de réseaux et terminaux fluides modélisés au LOD 400.
