System for parameterizing nested families based on BIM (Building Information Modeling) technology

The invention relates to the technical field of informatization auxiliary engineering construction, and discloses a BIM technology-based parameterized nested family system, which comprises the following steps of: modeling each constituent part of a model by using a Revit metric conventional model; all the components are fused into a self-adaptive nested family by adding shared parameter information and performing model editing and arrangement; adding a calculation formula to the nested family, and calculating information such as quantity and volume of the nested family; importing a project for application, newly establishing a stage in project management, and selecting a required nested family for stage division; newly establishing a conventional model detail table, selecting a phase required to be extracted in a phase column, and adding a shared parameter field required for quantity extraction; selecting a filtering condition through a detail table filter to extract required field engineering quantity inform
