What / how?
2D-3D designs with our design partner subsequent production, or subsequent construction of a BIM model for existing buildings, based on the point cloud model.
When to use them?
The plans of an existing (or still under construction) building were not originally prepared in CAD (and/or not using BIM), but due to changing circumstances, their production became necessary afterwards.
Back modelling with professional engineering experts
Reverse engineering in CAD or BIM requires several steps and specific knowledge:
- 3D scanning or image-based modelling: retrofitting an existing building or object into a CAD system or BIM model begins with a laser scan of the object and digital capture.
- Analysis of point cloud data: the 3D scanner creates a 3D point cloud-based model consisting of millions of points, which provides an accurate picture of the spatial properties and location of the structure.
- Modelling: after cleaning the data provided by the point cloud, a special software solution is used to create a BIM model based on the point cloud, which not only tracks the geometry of the building, but also contains detailed information about the building.
- Verification and update: Once the model has been created, it is important to verify the results and update the model if necessary, as there may be deviations from reality that need to be corrected.
Whether it is an existing building that needs to be renovated or added to, or whether it is a replacement for the original documentation, back modelling can be an effective tool. Contact us and choose our service!
