At present,the creation of rebar model of slab-beam wharf on high-piles is difficult and low cost-effective,and cannot satisfy the drawing requirements.It is impossible to realize the delivery requirements based on rebar model in the design stage.We study component-level rebar model technology in design stage,including the creation,drawing,quantity calculation,parametric design and delivery of rebar model etc.Based on the method of combining Revit software and Revit API technology,we propose a parameterized integrated technology of rebar model creation and drawing,and apply it to the actual project.The results show that the technology can quickly create the required rebar model and drawings,which can provide references for the similar projects.
