Development of a 3D (CAD) model of the structure and measurement taking

The construction of the Lees light rail train station at the University of Ottawa consisted, among others, in building several complex metal structures. The load bearing structures were covered in various aesthetic components made from folded aluminium sheets. It was a real challenge to get the final plan of the built structure. Creadditive did a 3D plan of the different metal structures to extract the geometric features required to properly finish the project. This 3D plan of the structure avoided a lengthy manual and imprecise measurement taking process.


  • The large and complex metal structure required accurate measurement taking.
  • The structure in question is a metal support structure on which a decorative, precut and pre-folded aluminium sheet is hung. It was crucial to ensure that the mounting points match and can be superimposed so that the structure can be attached to the supports.
  • The measurements taken manually were not accurate enough to precut the aluminium sheet with confidence.


  • The particular geometries of the ceiling and structure required a rigorous precision to ensure the components can be properly assembled while respecting the vision of the architect.


  • A 3D plan was successfully completed. The unparalleled accuracy of the plan allowed for the extraction of precise and reliable geometric data.
  • The final steps were thus completed quickly and successfully.
