What is the main difference between conventional sketch and design sketch?

Basic sketch and design sketch are both important parts of basic art teaching. Basic sketch (also known as conventional sketch), as a basic course of painting art, focuses on texture, light and shade, sense of space, and treatment of reality and reality, and studies the basic laws of modeling. The main purpose of the picture is visual artistic effect. Design sketch (also known as structure sketch) focuses on the scale, perspective, three-dimensional space concept and internal structure analysis of the body, and trains the ability to draw design prediction diagrams. It is a professional basic course to express design intention. Basically suitable for all three-dimensional design majors (such as product design, modeling, sculpture, etc.). The main purpose is the accuracy of perspective and structural analysis.

As a form of sketch, the rudiment and embryo of basic sketch were generally formed as early as the Renaissance. Introduced to China at the beginning of the last century, the laws that have been basically followed so far can be said to be relatively established. Design sketch is relatively young, although the teaching of design sketch started in Bauhaus school in Germany in 19 19. But it was not until 1980s that it was introduced into China, and it was not until 1990s that it really began to design the teaching system in depth. .
