Scan-to-CAD
Produce measured drawings from capture data.
Drawing scale and required detail are agreed in the scope.
Mapping & LiDAR
Turn captured building or plant geometry into usable drawings and models.
Reality capture begins with registered measured geometry; scan-to-CAD and scan-to-BIM add progressively more interpreted/modelled structure.
A BIM level of detail must define what is modelled, what is inferred and what remains inaccessible.
A static 3D mesh is visual geometry; an operational digital twin additionally needs asset identity, updates and workflows.
Produce measured drawings from capture data.
Drawing scale and required detail are agreed in the scope.
Model visible and measurable building elements.
Hidden services and concealed construction are not invented from surface scans.
Record accessible historic geometry and surfaces.
Protected-site access, capture and publication permissions may be required.
Link models to asset records and ongoing updates.
A static mesh or BIM model alone is not an operational twin.
A mesh depicts surfaces; BIM contains defined building objects and attributes. The intended model use and object scope must be agreed.
Ordinary surface scanning captures exposed surfaces only. Existing records or separately commissioned detection/testing are needed, and inferred elements must be labelled.
It defines which objects, geometry and attributes are included and how they will be checked. A generic detail label alone is not a complete specification.
Only where asset linkage, operational functions and update responsibilities are defined in the agreed scope. Static scan-to-BIM delivery does not imply a maintained platform.
Agree model purpose, detail, element scope and acceptance checks.
Separate measured objects from inferred or inaccessible geometry.
Deliver native/exchange formats with a defined coordinate and revision basis.
Drawing scale and required detail are agreed in the scope.
Hidden services and concealed construction are not invented from surface scans.
Protected-site access, capture and publication permissions may be required.
