Three-dimensional space positioning surveying and setting-out system

The invention belongs to the technical field of concrete, and particularly relates to a three-dimensional space positioning surveying and setting-out system, which is characterized in that relative coordinates of a project are established on an AutoCAD plane graph or a coordinate system is established by using a total station intersection method according to municipal axis net coordinate points provided by a project department; on the rhino 1: 1 three-dimensional entity model, horizontally sectioning the corresponding elevation of each required node to form a plane graph, picking up the coordinates of the control point, and carrying out lofting and control by using a high-precision total station; in the view and drawing process, various problems existing in a drawing can be found earlier, and technical preparation is made for manufacturing and mounting of the fair-faced template in advance; due to the fact that bidirectional communication is achieved between the total station and the computer, measurement dat
