step 2: converting the CAD comprehensive pipe diagram into a BIM model;
and 3, step 3: the BIM model is checked for pipeline spacing based on pipeline specifications.
In step 2 of this embodiment, converting the CAD draft into the BIM model specifically includes:
layering the CAD pipe comprehensive graph, wherein each layer only comprises a type of pipeline and a type of pipe point;
