Level of Development (LOD) standards, established by the American Institute of Architects (AIA) and BIMForum, define how much an element's geometry and non-graphic data can be relied upon at each project stage.
Clear LOD scoping prevents both under-modeling and excessive data bloat in project BIM models.
Learn to design across all LOD tiers with our Revit Training Courses.
