Scan-to-BIM SIG

Convert point cloud data into 3D BIM models

ODA is developing the industry’s first Scan-to-BIM SDK

Point cloud
AEC objects
BIM models
Laser scanning has become a mainstream technology for digital twins
And today the ability to optimize workflows with huge point cloud data
is a real competitive advantage for BIM application vendors.
Scan-to-BIM is a toolkit for BIM
software development
that provides conversion
of 3D laser scan data
to a parametric 3D
BIM model.
Point Clouds Polygonal
B-rep objects BIM
+ increased data
+ are the easiest
to render and visualize
+ precise geometry + actual building elements
+ represent complex
objects with a finite
number of elements
+ faster than other representations + hold up on all resolutions + reliability
– petabytes
of data
+ allows creation of more organic looking designs + object has general properties + eliminate costly mistakes during construction
- cannot create
mathematically perfect curves
- a large number
of models on the screen
+ relatively simple
to convert to the wireframe model
+ enhance construction safety management
- lack the precision
of B-Rep
- imprecise - objects are not classified + 3D model can
replace thousands of drawings
- no info on surfaces,
cannot be used natively
for rendering or manufacturing
- polygonal modeling
is time consuming
- can’t be used
in BIM as is
+ higher quality results

Use Cases

Prospective applications of Scan-to-BIM SDK in different construction project phases:

3D design with scan-based site models
Quality assessment/Quality control
Virtual installation for prefabricated building components
Digital reproduction of construction components
Operation and Maintenance (O&M)
Performance analysis
Facility Management


Polygonal surface reconstruction from the scanned point cloud.

The process of rebuilding mesh geometry from the scanned point cloud.

The reconstructed surface mesh should be optimized for virtual design workflows and should match the original geometry from which the scan was taken.

Mesh models can be edited to remove noise and interference objects.

The SDK is designed to work with both structured and unstructured point clouds.

Classification of polygonal model objects into common AEC objects such as walls, doors, windows, etc.

The classification of the elements in the point cloud to create ‘smart meshes’ that show specific data such as walls, windows, MEP or structural elements.

The first stage of the project will focus on the following BIM objects: walls, floors, ceilings.

The second stage of the project will extend the set of supported objects to include openings, doors, windows, pipes, ducts, conduits and others.

Conversion of polygonal model objects to B-Rep objects.

Boundary representation (B-Rep) is widely used in BIM software to represent the geometry of AEC objects.

Transformation of a polygonal model to a B-Rep model allows the model to be used in a natural way for BIM applications with a wide range of available editing operations for the resulting geometry.

Conversion of classified objects to product-specific representations - IFC, Revit, and other BIM formats.

The SDK automatically converts classified walls, windows, doors, floors and other objects into family groups for use with IFC, Revit and other popular BIM software.
