Benefits of 3D CAD modelling with Lumoview
Whether you need a simplified existing model or a highly detailed custom model, we deliver exactly the 3D CAD model you need for your project phase.
Reliable basis for energy simulations
A valid 3D CAD model is absolutely essential for any energy simulation or calculation. Whether for shading analyses, thermal bridge evaluation or detailed quantity determination: our data is structured geometrically so that it can be processed directly in common BIM or energy calculation software. Such an energy model provides reliable data for your renovation concepts.
Maximum planning reliability through to accurate as-built data
Our digital building models help avoid surprises during construction by making complex conditions visible—from complicated roof geometries to critical utility routes. This transparency supports design comparisons and renovation concepts while providing the necessary data to identify risks early and create reliable cost estimates.
Compatible: Seamless BIM workflows through scan-to-BIM
Modern planning, CAD, and BIM tools increasingly rely on 3D as the standard format. Our Scan-to-BIM workflow enables smooth integration into modern software ecosystems and automated Building Information Modeling processes. This ensures that your as-built data remains future-proof and interoperable across systems.
Exactly the level of detail your project needs
From simplified as-built models to highly detailed architectural models, Lumoview provides the exact level of detail required for each project stage—no more and no less. Choose a simplified model for quick simulations or a detailed architectural model for precise planning. We deliver the right model for your needs.
The right 3D CAD model for every use case
We measure your building room by room with our LumoScanner and, optionally, also capture the building envelope using drone flight. We then create a
3D CAD model that exactly meets your needs. Our digital model building transforms the scan data into an accurate 3D as-built model, which is available in various levels of detail (LOD) and can be flexibly adapted to your specific requirements – ideal for complex planning and detailed building analyses.
Levels of detail at a glance
Level 1: Simplified 3D simulation model
The simplified 3D CAD model provides basic building data with standardised elements and some simplifications. It forms an efficient and precise basis for energy simulations, energy consulting, facility management and initial renovation planning work, such as cost calculations. We focus on the space-defining geometry and deliberately avoid unnecessary complexity in order to maximise performance in your simulation software.

Frequently asked questions about our 3D CAD data
As standard, we supply open formats such as IFC (Industry Foundation Classes), which are compatible with most CAD and BIM programmes. Native formats such as RVT (Autodesk Revit) or DWG are also possible. Please contact us for special requirements (e.g. HottCAD).
- Level 1 is a simplified model, ideal for energy simulations. Walls are represented as idealised surfaces without thickness, windows and doors are simplified openings.
- Level 2 (architecture) is a detailed architectural model for planning purposes. Here, walls have real thicknesses and multiple layers, windows and doors have frames and sashes, and the roof truss is represented including rafters.
- Level 3 is a customised model that includes all the requirements you need.
The standard Levels 1 and 2 do not include any technical building equipment such as heating, ventilation or electrical systems. If you require these elements, we offer them as an optional service in Level 3 (customised).
Our models are based on precise laser scans (LumoScanner). Level 1 focuses on simplified geometry. Level 2 precisely dimensions components such as windows and doors (priority: manual measurement > scan > photo). Level 3 provides detailed modelling according to your specific requirements.
Yes. The Lumoview Level 1 (Simplified) model is specially designed to have a "lean" 3D geometry (only space-defining elements). This facilitates import and calculation in common simulation software.
In the standard packages (Levels 1 & 2), modelling ends at the building envelope, i.e. the terrain or outdoor facilities are not included. However, we can model these for you in Level 3 (Customised) on request.
In Level 1, a simplified roof geometry (including dormers) is created.
In Level 2, main rafters are shown, but no diagonal or complex geometries. Precise external roof geometry is possible with drone flight.
For special and specific requirements, we create a detailed model in Level 3 based on your specific requirements.
The delivery time depends on the desired level of detail, the complexity of the building and the size of the building. We would be happy to provide you with a precise estimate without obligation.
2D plans only show sections, but not connections. A 3D model makes spatial situations visible and is essential for energy simulations, shading analyses and BIM processes.
That depends on your intended use:
- Level 1 (Simplified) is the right level of detail for energy simulations and facility management. It offers simplified geometry (only space-defining elements) and idealised 2D surfaces without wall thickness.
- Level 2 (Architecture) is the right level of detail for architectural planning and scan-to-BIM. It includes all elements visible in the room, multi-layer walls with real thicknesses, and a precise subdivision of windows and doors.
- Level 3 (Customised) is suitable for the most demanding requirements. It is a detailed model based on your specific requirements.
The cost depends on the level of detail you choose. Feel free to contact us and tell us what you need.
