Interior design is to create an indoor environment with reasonable function, comfort and beauty and meet people's material and spiritual needs by using material and technical means and architectural design principles according to the nature, environment and corresponding standards of buildings. This kind of space environment not only has the use value and meets the corresponding functional requirements, but also embodies the spiritual factors such as historical context, architectural style and environmental atmosphere. The purpose of interior design is to create an indoor environment that meets people's material and spiritual needs. Modern interior design is a comprehensive indoor environment design, which includes not only visual environment and engineering technology, but also physical environment such as sound, light and heat, psychological environment such as atmosphere and artistic conception, and cultural connotation. Edit this paragraph, and make it clear that interior design refers to the preparatory work to meet certain architectural purposes (including people's requirements for its use function and visual feeling), as well as the value-added preparatory work for deep processing of existing building interior space. The purpose is to make specific materials ready for qualified products in terms of technology and economy under limited feasibility conditions. It requires not only engineering knowledge, but also artistic theory and skills. Interior design evolved from the decorative part of architectural design. He recreated the internal environment of the building. Interior design can be divided into two categories: public building space and home. When we talk about interior design, we will also mention some important terms, such as moving lines, space, color, lighting, function and so on. Interior design generally refers to any related objects that can actually be built indoors, including: walls, windows, curtains, doors, surface treatment, materials, lighting, air conditioning, water and electricity, environmental control system, audio-visual equipment, furniture and decoration planning. The editor's understanding of the meaning of interior design and its relationship with architectural design are analyzed from different angles and different emphases. Many scholars have many profound insights, which are worth our serious consideration and reference. For example, they think that interior design is "the continuation and deepening of architectural design, and the re-creation of indoor space and environment". It is considered that interior design is "the soul of architecture, the connection between man and environment, and the combination of human art and material civilization". Mr. Dai Nianci, a senior architect in China, believes that "the starting point and focus of architectural design is connotative architectural space, and the spatial effect is the goal pursued by architectural art, while interfaces, doors and windows are the necessary subsidiary parts of space. The subordinate part is the material basis of space and plays a decisive role in the perception of the use of connotation space, but it is a subordinate part after all. As for the appearance, it is only the inevitable result of the connotation space. " According to W.Platner, an architect, interior design is "much more difficult than designing a building with these internal spaces", because indoors "you have to deal with people more, study people's psychological factors and how to make them feel comfortable and excited. Experience has proved that this requires more experience and more specialized training than dealing with structures and building systems. " G.Adam, former president of American Association of Interior Designers, pointed out, "Interior design involves more than simple decoration, and their concerns have extended to all aspects of life, such as the design of houses, offices, hotels and restaurants, improving the indoor design rate of labor production, barrier-free design, compiling fire prevention codes and energy-saving indicators, and improving the utilization rate of public facilities such as hospitals, libraries and schools. In short, it gives comfort and safety to all kinds of people in the indoor environment. " EoPonomaleva, a Belarusian architect, believes that interior design is to design "an artificial environment with visual limitations to meet people's physiological and spiritual requirements and ensure the needs of life and production activities", and interior design is also "the interdependence and close combination of function, spatial form, engineering technology and art". Edit the research object of this paragraph. The research object of interior design is simply to study the closed surface and content of the interior space of the building. It is customary to divide interior design according to the following standards: according to design depth [1]: interior scheme design, interior preliminary design and interior construction drawing design.
