[0002] Generally refers to civil engineering, civil engineering refers to the planning, construction and maintenance of all infrastructure related to water, soil and culture. General civil engineering projects now include: houses, roads, water services, canals, flood control projects and transportation. In order to ensure the accuracy of the civil engineering measurement process and the accuracy of each position during construction, it is necessary to determine the construction position of each structure by laying out the lines. On-site laying out the lines is to facilitate the construction of workers and to be able to strictly follow the design drawings for construction. Generally speaking, all building axes can be called major lines, and the corresponding minor lines are the edge lines and dimension lines of the structural components. The main idea of ​​laying out the lines is to copy the dimensions of the design drawings to the ground according to the dimensions shown in the diagram. Laying out the lines is to provide a dimensional basis for all construction. Generally speaking, laying out the lines is done by rotating the laying out line roller, etc., to release the lines and determine the position.
