1.1.1 Non-Graphic Information
All calls for non-graphic information have been deleted from Part I and addressed in Part II
1.1.2 “No-fly zones”
Where zones that are not to be penetrated by other elements are required by code, operational, or structural considerations (door swings, electrical panel access clearance, foundation element areas or bearing influence, etc.), an item has been added to LOD 300 definitions calling for the zones to be either modeled to facilitate clash detection or accommodated by model-checking software.
1.1.3 Opening Elements (doors, windows, etc.)
Existing LOD 350 calls for modeling of rough opening deleted, moved to definitions of walls, floors, and roofs.
1.1.4 Openings and Penetrations in Walls and Similar Elements
- LOD 300 definitions have been adjusted to call for major openings such as windows, doors, and large mechanical elements to be modeled to nominal dimensions.
- LOD 350 definitions have been adjusted to call for all penetrations to be modeled to rough opening dimensions.
- Where elements such as MEP distribution components penetrate other elements such as walls, the existing LOD 350 calls for modeling of the penetration element itself (e.g. sleeves) have been clarified.
