[0002] The drawing board plays a crucial role in the drawing device for bridge design. The drawing board is usually made of sturdy and durable materials, such as an aluminum alloy frame with a high-strength plastic panel or solid wood. The aluminum alloy frame ensures the stability of the drawing board, is not easily deformed, and can withstand various pressures during the drawing process. The plastic panel has a smooth surface, which facilitates the smooth movement of drawing tools and has a certain degree of wear resistance for long-term use. The solid wood drawing board has a natural texture and good stability, giving a professional feeling. The structural design of the drawing board is also very important. Generally speaking, it has a flat surface to ensure that the drawing paper does not show undulations or unevenness during the drawing process. There may be certain protrusions or grooves at the edge part to fix the drawing paper and prevent it from sliding during the drawing process.
