Autocad Level Of Detail3/22/2021
We provide part numbers on the drawings and a cutting ticket for the Workshop.We dont create Piece Part drawings One timber rail is pretty much the same as another.
I want to show you how we use LODs to lighten the load on Inventor. We arent going to talk about Positional Representations today. Simply right click on the Level of Detail node in the Assembly browser and chose New Level of Detail. Select the LOD you want to use to create your drawing view from. If you want to quickly filter components off in your drawings, use an LOD rep in conjunction with View reps instead. Unfortunately I am using Inventer 2012 and will have to relearn the mindset. Instead, the schematic design model deliverable may contain modelled elements at various levels of development. During the design process, building systems and components progress from a vague conceptual idea to a precise description. In a model though, a generic component placed approximately can look exactly the same as a specific component located precisely, so we need something besides appearance to tell the difference. In the past, this issue has been sidestepped with all-encompassing disclaimers that basically say, Since some of the information in the model is unreliable, you may not rely on any of it. In a collaborative environment, where people other than the model designer are depending on information from the model in order to move their own work forward, the design work plan takes on high importance it is necessary for the model users to know when information will be available in order to plan their work. Level of Detail is a measure of the amount of information provided. Because it is only a measure of quantity, the underlying assumption is that all provided information is relevant to the project and so can be relied upon with certainty. In essence, Level of Detail can be thought of as input to the element, while Level of Development is reliable output. Information related to the Model Element (i.e. HVAC, etc.) can be derived from other Model Elements. LOD 200: The Model Element is graphically represented within the Model as a generic system, object, or assembly with approximate quantities, size, shape, location, and orientation. Non-graphic information may also be attached to the Model Element. LOD 300: The Model Element is graphically represented within the Model as a specific system, object or assembly in terms of quantity, size, shape, location, and orientation. LOD 350: The Model Element is graphically represented within the Model as a specific system, object, or assembly in terms of quantity, size, shape, orientation, and interfaces with other building systems. LOD 400: The Model Element is graphically represented within the Model as a specific system, object or assembly in terms of size, shape, location, quantity, and orientation with detailing, fabrication, assembly, and installation information. LOD 500: The Model Element is a field verified representation (i.e., as-built) in terms of size, shape, location, quantity, and orientation. Non-graphic information may also be attached to the Model Elements. For example Structural Column Base Plate (as depicted above). Building systems are developed at different rates through the design process for example, design of the structural system is usually well ahead of the design of interior construction. At completion of the schematic design phase, for example, the model will include many elements at LOD 200, but will also include many at LOD 100, as well as some at LOD 300, and possibly even LOD 400. As previously stated, project models at any stage of delivery will invariably contain elements and assemblies at various levels of development. As an example, it is not logical to require an LOD 200 model at the completion of the schematic design phase.
