It's not difficult to do, but you have to learn a lot to become an expert! 1. Know drawing (civil drawing, mechanical drawing), and be proficient in drawing design drawings and construction drawings that meet national standards. 2. I can understand all kinds of civil construction drawings. Besides structural construction drawings, I am also very skilled in water supply and drainage (water supply and drainage) engineering drawings, heating engineering drawings, ventilation engineering drawings, electrical lighting and fire fighting engineering drawings. This is very important for interior decoration design: it can avoid the conflict between decoration design and civil facilities, and can carry out decoration design more thoughtfully and appropriately. 3. Understand perspective, can quickly draw indoor perspective skeleton line drawing, accurate perspective: can draw axonometric drawing (fixed axis and included angle between axes). This is the basis of drawing a good rendering. 4. Can draw color effect diagram, can correctly express the sense of space, texture, color change, subjective feeling of furniture and equipment, light environment effect, etc. 5. Be familiar with the functions, characteristics, size specifications, colors, decorative effects and material prices of various civil engineering materials and building decoration materials (PPP). ), in order to correctly select materials and properly match materials. 6. Understand the basic structural types of buildings, especially the advantages and disadvantages of various structures and common construction methods. 7. Have knowledge and accomplishment in architectural style, interior and furniture style, and be familiar with various basic features and variants. Also understand the historical development of various furnishings. 8. Have the knowledge and skills of surveying and mapping, be able to correctly record field measurement data and collect data for design. 9. Be familiar with the decoration construction technology to ensure the decoration quality. 10. Extensive cultural knowledge and cultivation are conducive to improving the level of interior design. 1 1. Be good at collecting and accumulating design data, such as sketching, surveying and mapping, taking photos, copying and recording, and constantly accumulating useful design data. 12. Master the skills of professional investigation, whether it is a comprehensive PPP investigation or a professional PPP investigation, you can grasp the main points and get the information that designers should have in order to facilitate interior design work. 13. High-quality models will be made independently, which requires designers to understand materials and technological practices, and will use necessary tools and equipment. This is the practical ability that designers should have. 14. Can take photos, know darkroom technology and take photos. These skills can also be mastered by designers. 15. Interior designers can also learn computer-aided design (CAD) and master the skills of drawing design drawings, construction drawings and renderings with computers. 16. You should have knowledge and accomplishment in garden art, bonsai and flower arrangement art, and know the special PPP and function of greening trees and flowers. 17. The 3DMAX project should be deeply studied and understood. 18. Strengthening the understanding of electric light source, light source products and lighting technology is beneficial to indoor lighting design. 19. interior designers should learn sociology and understand the relationship between people, people and classes, classes and lifestyles, and needs, which is helpful for good design. 20. Interior designers should also have a deep understanding of environmental science and keep up with the new development trend. Add two more items: first understand the physical dynamics and chemical biology design strategy, which can reduce or even avoid the property loss in decoration construction. Interior design can "strategize and win the future" for the project. On the other hand, the real project cost comes from the design of interior designers. To save money, we must master and control the cost from the design, and the quotation without design has no basic budget. This requires attention to the following points when choosing interior designers. 1 experience. Can interior designers quickly understand the owners' problems and make reasonable suggestions quickly? See if it handles enough cases and has rich experience. 2. Creativity. In the process of talking with you, can he look at the building plan according to your situation, conceive freely, quickly and accurately, sketch out the main design drawings with a pen, and explain his design intention at the same time? 3. Personality. A docile designer has no personality standards. No matter the choice is good or bad, all the decorations seem to serve the owners well, but they are actually not responsible for the owners. The works designed by designers with personality can make your home improvement different from others' and have the feeling of "tailor-made". 4. Comprehensive cost. The deeper the interior designers know about the varieties of decoration materials and the prices of related decoration projects, the more they can arrange the owners' funds reasonably, so that the decoration materials can serve the interior design, save materials, effectively select materials and replace them reasonably, save money for the owners and maximize their intrinsic value. 5. Related issues. Interior designers' understanding of related architectural problems is conducive to the smooth progress of decoration construction, solving construction problems and closely connecting with practice. If the wall moves, the process is simple and the effect can be achieved. Furniture combination, what kind of finished furniture is economical and practical. Decorate articles effectively. 6. Comprehensive ability. The content of decoration engineering is unique and complicated. Vertical ability is a must for interior designers. Horizontal ability and the breadth of designer's knowledge level are the key points that distinguish high-level designers from general interior designers. Can solve and meet the comprehensive needs of the owners. 7. New technology. Designers' understanding of finished system, household appliances, digital network era and its application in home. Decorative materials reflect environmental protection and deal with the acoustic environment in family decoration. The ability to solve new lifestyles. Decoration should meet the development needs of technological innovation. 8. Decorative culture. Interior designers' understanding of culture and rational use of styles and genres can make the decoration level higher. Meet different levels of consumer demand. 9. Moral concepts. Interior design works are just like people, on the other hand, interior design is more predictable, and everyone is very different. The more predictable, the less likely it is to go wrong in the future, and the more worry-free the owner will be. Grasping the owner's situation and then choosing the appropriate construction methods and procedures can save the owner's energy. With the correct moral concept, you can also have a good service level. 10. artistry. Art is an important part of decoration, and decoration itself is also a kind of advanced enjoyment. The expression of interior design value level is ultimately the expression of artistic content. When creating an ideal space environment, let it become an elegant work of art.
