Pitched roof (Rough)

ARC-ROOF-PITCH

Rough dimensions according to structural engineering for pitched roofs in design development and permitting stages.

Description

  • Coarsely dimensioned pitched roof geometry according to the structural and envelope concept.
  • Used for coordination between architecture and structural engineering, not for execution planning.

Modelling guidelines

  • Model as a simplified volume or roof surface; pitch according to the sketch concept.
  • Do not model roof build-ups, cladding, or detail connections.
  • Early: concept via sketches as structural sketch in the architecture model; verify exclusion zones from the structural engineer.
  • Later: align the same components with Reference in the structural model as well.
  • Use an IfcMaterial that corresponds to the actual material class.
