Window Element

Key Features

• Multiple window types: fixed, casement, sliding, tilt
• Configurable frame and glass panes
• Adjustable number of divisions
• Automatic wall cutting when attached
• Sill height control for positioning
• Transparent glass with realistic appearance

Fixed Window

Non-opening window, typically used for views or light.

• Cannot be opened
• Maximum glass area
• Common for large picture windows

Casement Window

Side-hinged window that swings open. Most common type.

• Opens outward or inward
• Good ventilation
• Easy to clean from inside

Sliding Window

Window with panels that slide horizontally.

• Space-efficient operation
• No swing clearance needed
• Popular for modern designs

Tilt Window

Window that tilts inward from the top for ventilation.

• Secure ventilation option
• Common in Europe (tilt-and-turn)
• Weather-resistant when open

Standard Casement Window

Creating a typical two-pane casement window:

This creates a 120x120cm casement window with 2 panes, positioned 90cm from the floor.

Large Picture Window

Creating a fixed picture window:

This creates a 200x150cm fixed window with a single pane, positioned 60cm from the floor.

Wall-Attached Window

Attaching a window to a wall with automatic cutting:

This window attaches to face center 8 of wall1 and automatically creates an opening.

Multi-Pane Window

Creating a window with multiple divisions:

This creates a 180x120cm window with 3 panes and white frame.

Transparent Glass

Windows are rendered with semi-transparent glass that:

• Shows light blue tint (#87CEEB)
• 30% opacity for realistic transparency
• Double-sided rendering for visibility from both directions
• Interacts naturally with scene lighting

Frame Materials

The material parameter controls the frame color:

• #FFFFFF - White (most common)
• #333333 - Dark gray/anthracite
• #8B4513 - Wood brown
• #CD853F - Light wood

Automatic Wall Cutting

When autocut is enabled and refpos references a wall, the window automatically cuts an appropriately sized opening.

• Opening matches window dimensions
• Cutting volume extends through typical wall thickness
• Resizing the window updates the wall opening

Sill Height vs. Attachment

The sillHeight parameter behaves differently based on attachment:

• Standalone windows: sillHeight positions the window bottom from z=0
• Attached windows (with refpos): Window bottom aligns with the attachment point; use face centers at appropriate heights

Reference Position Format

The refpos parameter uses the format wallname.faceindex:

• wall1.5 - Face center 5 of wall1
• wall1.8 - Face center 8 of wall1

Wall face centers are automatically generated along the wall surface.

Recommendations

• Standard sill height is 90cm (comfortable for viewing while standing)
• Bathroom windows should be higher (150cm+) for privacy
• Use 2 divisions for most windows, 1 for small or picture windows
• White frames work with most designs; use anthracite for modern styles
• Consider sun position when placing large windows

Common Applications

• Residential architecture visualization
• Interior design presentations
• Building configurators
• Daylighting studies
• Facade design

Window not cutting wall

Verify that autocut is set to true and refpos correctly references the wall. The refpos format should be "wallname.faceindex" (e.g., "wall1.5").

Window at wrong height

For attached windows (with refpos), the window bottom aligns with the attachment point. Choose a face center at the appropriate height, or adjust z position. For standalone windows, use the sillHeight parameter.

Glass not visible

Glass is semi-transparent and may be hard to see against light backgrounds. View from different angles or ensure there's contrast behind the window.

Divisions look wrong

The divisions parameter creates equal-width panes. For unequal divisions, consider using multiple windows side by side or custom modeling.

Frame too thick/thin

Adjust the frameThickness parameter. Default is 5cm which works for most cases. Use smaller values for slim modern frames.
