description The invention relates to an automatic comprehensive drawing method and system, and the method comprises the steps: obtaining representative points of polygons of projection planes of all houses, and forming a representative point cluster; based on the unconstrained Delaunay triangulation network mathematical model, constructing an associated triangulation network of the representative point cluster of the house projection plane, and constructing a minimum spanning tree for the associated triangulation network; cutting the minimum spanning tree to form at least one polygonal aggregation tree; extracting all vertexes of a house projection plane polygon in each polygon aggregation tree, generating a new associated triangulation network based on an unconstrained Delaunay triangulation network mathematical model, and performing triangulation based on constrained edges; and carrying out triangle fusion on the new associated triangulation network after constraint processing. The system comprises a representative poi
