The invention discloses an integrated standard
engineering structure creation and
system design method based on BIM (
Building Information Modeling). The method comprises the following steps: firstly, determining the location of main equipment, and drawing an equipment base and reserving the equipment spatial position; secondly, determining the type of integrated equipment, selecting usage families corresponding to
system equipment,
pipe fittings and pipelines and performing
secondary development and design on each selected group, drawing into an integrated standard
engineering structure, performing parameterized setting on the standard
engineering structure, and configuring an in-out port; and arranging the standard engineering structure in the reserved position, and connecting the remaining pipelines and
pipe fittings to complete the
system drawing. The integrated standard engineering structure creation and system design method based on the BIM provided by the invention integrates the traditional family in the BIM drawing, and integrates the equipment with end pipelines and
pipe fittings into the standard engineering structure; and in the BIM drawing, the addition of pipeline fittings is one of the main
workload, and the
integrated design method can improve the drawing efficiency, reduce the mechanical drawing time, and increase the
layout flexibility and versatility.
