PointCab

The company Laser Scanning Architecture applied a laser scanner FARO 3D for the three-dimensional capture of a historical industrial building. Then, the generated 3D data was analyzed and interpreted with AutoCAD Architecture and PointCab. Using the software FARO Scene, the scan data was analyzed in image mode as well as in pixel mode. In the model, analysis and geometrical measurement were realized in colorful panoramic scenes. Various perspectives were possible and individual parts of the model could be hidden.

Employing the software PointCab, a 2D analysis was realized in AutoCAD Architecture. With PointCab, orthographic 2D images of the building were generated at arbitrary positions in the data model.

Facts:

• in situ laser scanning without physical contact
• effort: ca. 3 hours
• complete visual and geometrical analysis of the 3D data within one day
• generation of axonometric or perspective views from any position
• generation of CAD models
• visual control of planning grid, height of ledge and details by visualisation of scan image and CAD contents
• different types of visualization (e. g. show or hide any parts oft he model, video animation with modifiable tracking shots)

Why PointCab?

• orthographic 2D images of the building
• positions in the scan are arbitrary
• building was captured in detail: sills, various shapes etc.
• precise dimensioning
• basis for efficient replanning and conversion
• use of reference edges of the building

Extremely accurate creation of as-built documentation: sills, pilasters, and other shapes.
