[0002] Engineering design refers to the activity of comprehensively analyzing and demonstrating the technical, economic, resource, and environmental conditions involved in a construction project based on its specific requirements, and then compiling construction engineering design documents. It is a process in which people use scientific and technological knowledge and methods to create targeted engineering product concepts and formulate plans.

[0003] Patent application number 202322802076.3 discloses an auxiliary drawing tool for construction engineering design, including a placement plate. The top of the placement plate is provided with two clamping mechanisms, which are located on the left and right sides of the central axis of the placement plate, respectively. Each clamping mechanism includes a movable bar and L-shaped sliders fixed on the front and rear sides of the movable bar. The two L-shaped sliders are connected to the front and rear sides of the placement plate, respectively. The bottom of the movable bar has a strip-shaped groove, and the inside of the strip-shaped groove is provided with a pressing bar. The pressing bar is connected to the inside of the strip-shaped groove through a compression spring. The top of the pressing bar is fixedly connected with three connecting rods, and the top of the connecting rods penetrates the inner top wall of the strip-shaped groove.
