Floor plan diagrams are indispensable during the design process as they help designers and clients visualize and understand the spatial organization of a space.
  3. Elevations: Elevations are 2D drawings that show the vertical plan of a space, including walls, windows, doors, and other features. They are important because they help to communicate the visual aspects of a design, including the size, scale, and proportion of different elements in a space. Elevation diagrams are an essential tool in interior design that provide a vertical representation of a space or a specific wall within a space. Elevation diagrams are created by drawing a 2D view of a wall, including its height, width, and the arrangement of architectural elements such as windows, doors, and built-in features.

Creating 3D model diagrams is an excellent way to visualize and communicate interior design concepts. 3D models provide a realistic representation of a space, allowing designers and clients to explore and experience the design in a more immersive manner. Dedicated 3D modeling software, such as 3ds Max, Rhino, or Blender, offers more advanced capabilities for creating intricate and detailed 3D models. You can create 3D interior design diagrams via these models.
