WHAT IS LEVEL OF DETAIL (LOD)?
Level of detail (LOD) describes the depth and detail of information included within survey data. Survey data will be either 2D or 3D information, such as 2D CAD drawings and elevations or 3D models.
LOD is measured in various formats, ranging from LOD 1 (100) to LOD 5 (500). The most common level of detail for measured building surveys are LOD 2, LOD 3 and LOD 4. You can download our guides for comparisons of LOD. Our 3D guide demonstrates highly detailed information on specific elements including stairs, walls, windows, lofts and more.
Our level of detail definitions directly relate to standard set by The Royal Institution of Chartered Surveyors (RICS). You can read about LOD on the RICS website here.
A GUIDE TO
LEVEL OF DETAIL FOR 3D MODELS
How can our guide to LOD for 3D models help you?
- Define what level of detail is
- Understand what’s included in each LOD
- Compare model examples including walls, beams & columns, doors & windows, stairs and lofts
- Define MEP and modelling in commercial and residential buildings
- Increase your understanding of LOD in different survey types
- Learn about the methodology and techniques of data collection
- Learn about accuracy and modelling within models and point clouds
- Define Revit compatibilities
We are happy to assist in tailoring the project to your exact requirements. This guide has been designed to illustrate the varying levels of detail (LOD) that go into the 3D models and to help you choose the right model for your next project.
A GUIDE TO
LEVEL OF DETAIL IN 2D MEASURED BUILDING SURVEYS
How can our guide to LOD in 2D measured building surveys help you?
- Define what level of detail is
- Understand what’s included in each LOD
- Compare real-life examples including floor plans, elevations and sections
- Increase your understanding of LOD in different survey types
We want to ensure you have the correct information to get your project off to the best possible start. This guide is designed to illustrate the varying LODs available to you within a 2D-measured building survey and choose the correct drawings for your project.
