3.2.5. Three-Dimensional Modeling

After completing the point cloud feature extraction, the attribute information can be used for the automatic modeling rules [17,18,37]. In the BIM operating platform, this study uses the Revit software produced by Autodesk for overall modeling display, component information viewing, conflict analysis, and other functional purposes. Design using Dynamo (a visual plug-in program for Revit) in the automatic modeling stage is implemented. Automatic modeling processes five parts: column, beam, wall, floor, and ceiling. Because the research objects are mainly preset components in the parameter library of Revit, several preset family types are directly selected as the modeling types in this study.
