Abstract：Based on the .NET software development toolkit of the AutoCAD platform,the detailed parameters of the structural components are obtained through the Dapper tool,the principle of the Thiessen polygon segmentation algorithm is utilized,and the segmentation of the linear boundary and spatial analysis are carried out by using the analytical library NetTopologySuite,which constructs the topological polygons,and then converts them into the basic geometric information required for the arrangement of points in the automatic fire alarm system combining the building area data with the structural component parameters. On the basis of the automatic arrangement of point‑type fire detector points,it further implements an automatic wiring function,automatically generates cable laying paths,and optimizes cable laying methods to improve the efficiency and accuracy of automatic fire alarm system design. Some difficulties and solutions encountered when dealing with linear boundary areas are discussed,as well as the advantages and future development of the software.
