Research Materials for the Study

The objective of this research is to create an automated design feedback workflow serving QTO for structural components using Dynamo, a BIM-assisted visual programming tool. A BPMN(Business Process Modeling Notation) Diagram drawn up with Visio software can clearly show the flow forms of data types and information between 'Client', 'Structure Engineer' and 'Estimator'; UML (Unified Modeling Language) Diagram can be used to classify, construct, document, interpret and visualize numerous elements of a dense system using a standardized language to make the data hierarchy clear and the information explicit; Revit Dynamo scripts are used to automate the design-feedback process; Detailed data of the study results are presented in Project Data.本研究旨在依托建筑信息模型（Building Information Modeling，BIM）辅助可视化编程工具Dynamo，搭建面向结构构件工程量提取（Quantity Takeoff，QTO）的自动化设计反馈工作流。使用Visio软件绘制的业务流程模型与符号（Business Process Modeling Notation，BPMN）图，可清晰呈现“客户”“结构工程师”与“估算师”三者间的数据类型与信息流转形式；统一建模语言（Unified Modeling Language，UML）图可依托标准化建模语言，对复杂系统的各类要素开展分类、构建、记录、阐释与可视化工作，从而明确数据层级、明晰信息内涵；本研究采用Revit Dynamo脚本实现设计反馈流程的自动化；研究结果的详细数据已收录于项目数据集（Project Data）中。
