# Create Apertures An aperture is an opening, hole, or gap within a room. Apertures should always be modeled as planar surfaces that are coplanar with the appropriate face of your room. If you have floor-to-ceiling windows on a face of a room, then the window edge should not overlap with any room face edge. Similar to rooms, there are three ways to add or draw apertures: 1. Select Geometries 2. Add by Window to Wall Ratio 3. Draw an Aperture ### Select Window Geometries and Add by Window to Wall Ratio {% embed url="" %} ### Draw Apertures {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
