Traditional Half-Round Window with Trim

Traditional semicircular half-round window Revit family featuring an arched frame profile with integrated exterior perimeter casing trim. Semicircular lunette geometry defined by a straight horizontal sill and a continuous semi-circular top arch. The unit integrates an outer perimeter trim casing that frames the arched sash and glass panel. The profile shows clean concentric offsets representing the exterior casing, main jamb frame, interior sash stop, and central glazing pocket. Modeled with planar simplicity, the fixed glazing provides an unobstructed view without intermediate muntins or division bars, emphasizing geometric clarity suited for transom placements, gable accents, or decorative feature fenestration across residential elevations.

The download is a 82 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.

Load this component directly into a Revit project and place it onto vertical host walls. Adjust instance sill height to stack above rectangular entry doors, multi-panel windows, or position freely within attic gable walls. Assign native project materials to the frame, sash, glass, and perimeter casing parameters to coordinate with exterior siding, stucco, or masonry details during technical documentation and perspective rendering.

Well suited for traditional residential elevations, classic villas, suburban developments, and heritage restoration schemes. Designers frequently implement half-round windows as clerestory highlights in double-height living rooms, entry foyers, and stairwells, or as decorative transom elements over standard casement groupings. Searches for semicircular clerestories, arched transom units, and lunette wall openings align directly with this fenestration family across schematic massing through detailed construction documentation sets.
