To demystify the concept of LOD BIM, let's explore this innovative approach in detail: LOD (Level of Development or Level of Detail), by definition in the field of BIM(Building Information Modeling*), represents the level of development of a digital model.
Because LOD has a major influence on the size and complexity of a BIM model, it's useful to distinguish between LOI (Level of Information), LOG (Level of Geometry) and to distinguish between several levels such as LOD 100, LOD 200, LOD 300, LOD 350, LOD 400 and LOD 500.
LOD can be interpreted as the degree of reliability of your BIM model. It's the degree to which an element's geometry and associated (non-graphical) information have been developed, including a certain level of LOD detail. We explain exactly how this works with a kiwi :
LOD = LOG + LAW
For this simplified representation of LOD = LOG + LOI, we've taken a kiwi as an example. Our LOD-kiwi is divided into LOG (geometry level) and LOI (information level) information.
LOG (Level of Geometry): Geometry level in LOD BIM
LL'extérieur, the visible part of LOD-kiwi, is the geometry level. It tells us about the appearance (geometry) of a product in the BIM model. The LOG, as in the construction model, gives us the level of geometric detail.
For example, EMCS 4.0 distinguishes 5 different levels or geometries, with LOG 1 representing a schematic or symbolic representation of a product, and LOG 5 a detailed, manufacturer-specific representation, including each LOD level of detail in BIM.
