WindowsHelm - Architectural Windows & Roller Shutters

Create a window type once. Place it throughout your project. Keep the shared design consistent while giving individual windows their own dimensions, materials and opening poses.

WindowsHelm is a parametric window add-on for Blender 5.2 LTS, designed for architectural modelling and visualization. Its Create / Place / Edit workflow makes the editing scope explicit, so you can see whether a change affects the type, a customized member or an independent window.

Reuse a design without losing individual control

Create named types for bedrooms, bathrooms, living rooms or balcony openings. Shared edits update inherited fields across their members. Choose Edit only this window to customize its own fields while keeping it in the type list. Other fields continue inheriting the shared design. Use type design restores inheritance; Unlink from type makes the active window independent.

Each window keeps its own placement, opening and shutter pose. Duplicated members retain their type and custom values. Copying a member into a new type does not move the original out of its group.

Eleven styles with detailed construction

Fixed, One casement, Two casements, Tilt and turn, Two sliding leaves, Single hung, Double hung, Awning, Hopper, Three panels and Double balcony door. Choose PVC, simple aluminium, thermal aluminium or wood profile construction. Wood includes oak, walnut and painted finishes.

Configure dimensions, glazing, frame and sash profiles, hardware and materials. Add a roller shutter with box, guides and belt-winder or motor mode. The exterior sill is optional and starts disabled for new default designs.

Place and pose

Place a type at the 3D cursor, prepared point objects or an existing vertical wall opening. Two-click placement locks the wall plane, then positions the bottom centre of the window. Preview its exterior direction and adjust depth.

Use independent opening controls or quick Closed, Open and Tilt poses where supported. Choose the active window or selected windows, with separate shutter controls and optional keyframes. Animate design properties and local motion for presentations or changes across a timeline.

Materials and daylight

Glazing offers a daylight-oriented interior mode and a physical refraction mode. Custom-material properties preserve your assigned materials through parametric changes. The add-on keeps your lighting, exposure and render setup under your control.

Included with the purchase

• WindowsHelm 1.0.0 extension, with the full Python source and GPL licence.
• English getting-started instructions, FAQ, support and privacy information.
• Six-page PDF user guide and a separate searchable documentation archive.
• Eleven bundled style preview icons.
• One complete edition with standard support through Superhive.

Requirements and scope

Supports Blender 5.2 LTS. Runs locally with no activation account, telemetry or third-party Python dependency. SceneHelm is not required.

Prepare wall openings yourself: placement does not cut walls or measure holes. Parametric design changes can replace manual edits to generated meshes. Use design parameters and custom-material properties for changes that should persist. Thermal profiles are visual models, not engineering certification. Future Blender-version compatibility is announced after validation.

Support and updates

Standard support covers installation, documented workflows and reproducible add-on problems in the supported Blender series. Contact the creator through the product's Superhive messaging channel; the first-response target is within 72 hours. Custom project production and private development are outside scope. Released WindowsHelm 1.x maintenance updates are included for existing buyers. Future major versions may have separate terms. No lifetime-maintenance promise or fixed development schedule is made. No support-renewal subscription is used.
