About this asset

Featuring a semicircular arch profile, this Revit family provides a classic half-circle window unit with tiered exterior casing and glazed infill. Designed with a true semicircular geometry, the unit features a broad arched outer frame flanked by layered exterior mouldings. Inside the stepped surround, an inner sash frame encloses a single pane of half-round glazing. The stepped trim delivers pronounced shadow lines, accentuating the radius above rectangular window configurations or door openings. Muted neutral tones on the perimeter trim contrast with the light internal framing and pale blue glass representation, providing clean architectural definition for both traditional and neoclassical exterior elevations.

The download is a 522 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Delivered as a wall-hosted Revit family, this component inserts directly into vertical host walls, automatically creating the correct semicircular rough opening cut. In the family editor or project environment, users can assign project-specific materials to the frame, interior casing, and glazing subcategories, ensuring consistency in rendered visualisations and accurate schedule generation across window elevations.

Ideal for single-family residential facades, heritage restorations, and bespoke villa designs, this transom-style unit functions effectively above standard entry doors or multi-lite casement banks. Architects seeking arched lunettes, decorative fanlights, or radius specialty glazing will find this asset suitable for formal elevations, stairwells, and cathedral living spaces. It coordinates naturally with pitched rooflines, stone lintels, and classical siding systems.
