About this asset

Half-circle arched transom window provided as a native Revit family, featuring stepped exterior casing and a semicircular glazed sash for wall assemblies. This window family models a semicircular geometric profile configured as a half-circle transom or gable unit. The outer frame features multi-tiered stepped exterior trim that surrounds an inset sash and a single semicircular glass pane. Flat horizontal baseline profiling defines the bottom sill interface, facilitating direct alignment above door transoms or standard rectangular window headers. Proportions follow a standard 2:1 width-to-height ratio typical of true half-round openings, delivering refined architectural sightlines suitable for traditional and transitional elevations.

Designed for architectural modeling within Revit, this wall-hosted family automatically cuts its semicircular opening upon placement into host wall geometry. Users can adjust placement height, sill elevations, and assign project-specific materials to the frame, glass, and exterior trim subcategories in the family properties dialog. The clean vector linework ensures accurate graphical representation across plan, elevation, and section sheets at medium and fine detail levels.

Commonly positioned above entrance doors, patio exits, and multi-unit casement assemblies, this arched transom window brings classic daylighting to residential villas, custom suburban estates, and boutique hospitality properties. It pairs naturally with divided-lite entrance systems, panelled exterior doors, and masonry or lap siding facades.
