Differentiating levels of detail (LOD): illustrations and explanations

What will you find in this technical guide?

Based on the objectives of a project and the uses projected around the digital model, it will be a question of defining the LOD of the various lots and objects modelled. Defining the right level of detail is decisive in order to obtain a model adapted to its use, and to optimize modeling costs.

However, some clients may have difficulty choosing the right LODs, in a context where few modeling standards are generalized.

This is why we invite you to discover in this document what these levels of detail correspond to for several selected lots, by specifying in particular:
‍

The degree of adjustment between the model and the point cloud, when the modeling is carried out using a scan to BIM method

Modeling details applied to different lots and objects

Specific information, which can be associated with objects.

In this context, we emphasize that this The purpose of the document is not to present an official nomenclature, but rather to share the fruit of our experience, by offering a fairly broad repository of information but applicable to a large number of projects.As part of our activity, this database allows us in particular toorienting correctly our BIM projects, of Suggest a framework clear for our customers and partners, while maintaining a certain flexibility in modeling.
