The invention provides a rapid refined modeling method for municipal
pipe network by using BIM, which comprises the following steps of: analyzing a regional map of which a
pipe network needs to be established and related data, carrying out preliminary modeling through map analysis, establishing a rough BIM model through Cill 3D
software, segmenting the model, respectively extracting component diagrams and model lines in the model, respectively segmenting a
component diagram and a model line, limiting the position of the segmented
component diagram according to needs, adjusting the height and the relative position of
pipe network distribution by the model line, parameterizing the
component diagram according to requirements, colliding the model line with the component diagram, and carrying out optimizing, establishing a
standard model of a municipal pipe network, generating a specific and complete
processing drawing, and generating corresponding data among all parts. Compared with the prior art, the method has the advantages that BIM modeling is faster, and the built model is higher in refinement.
