The traditional design process for pile foundations of high-piled wharves involves a lengthy cycle,with drawing and pile collision checks conducted across various software platforms with inconsistent drawing standards.To address the deficiencies in the design process,a hybrid technical approach of “Revit modeling+ZWCAD drawing output” is adopted.Through development methods such as C++ and C# (Add-in),a cross-platform software suitable for the digital design of pile foundations of high-piled wharves has been developed.The software modules cover functions including pile creation and editing,pile annotation,data query,collision checking,data statistics,drawing data export,and automatic drawing generation.The software fully leverages the advantages of BIM digital design and aligns with designers’ 2D design habits.It comes with multiple built-in parameterized components and constructs a full-process technical system for pile foundation BIM design,covering the workflow of “BIM modeling,data adaptation,collision checking,and standardized drawing output”.It realizes efficient and precise 3D digital design and drawing generation for pile foundations,and resolves the difficulties in the process of connecting 2D and 3D design,such as poor data interoperability,repeated modeling,and inconsistency between drawings and models.This provides a replicable pile foundation design solution for the industry
