Procedural Windows is an add-on that utilizes a node-based system to generate parametric window models directly in the viewport. It supports five main window styles: casement, fixed, sliding, single-hung, and double-hung. Each generated window includes appropriate profiles and sections based on the selected type.

The tool provides extensive customization options through an N-panel interface. Users can adjust dimensions, overall depth, frame and panel widths, mullion sizes, and shutter opening percentages. The add-on includes built-in PBR materials representing aluminum, UPVC, and wood finishes, offering 21 distinct structural combinations. It also features automatic UV mapping, adjustable bevel and subdivision levels, and 45 pre-configured presets to quickly populate architectural scenes.
