Opening / recess (architecture)

ARC-OPENING-VOID

Opening or recess in architectural components - masonry and non-load-bearing walls.

Description

  • Void in a wall, slab, or other architectural component for services, equipment, or construction requirements.
  • Binding for components carried only in the architecture model (non-load-bearing interior walls, architectural masonry).

Modelling guidelines

  • Model as an opening element and assign it to the voided architectural host.
  • Through opening as OPENING; one-sided or non-through recess as RECESS.
  • Name uniquely by storey and host component; do not carry structural penetrations here - use the MEP void request and the structural opening.
