A detailed 3D model was developed from point-cloud survey data to support technical analysis within a dense urban environment.
The work required careful interpretation of complex surrounding context and constrained site conditions. Survey-based geometry was prepared in AutoCAD and coordinated for an MBS-compatible downstream workflow.
Project challenge
Resolving dense urban context from survey information.
The model needed to represent numerous adjoining buildings, roofs, façades and openings with sufficient clarity for reliable analysis while remaining proportionate to the intended use.
Typical inputs
Coordinated source information.
Registered terrestrial and drone point-cloud data
