![]() Revit is a BIM software that allows us to create construction elements with parameters, so that elements can have properties such as measurements, categories, levels, materials, and coding capabilities such as the assembly code and keynote code.īy elements, models can follow construction processes and can be linked to tasks. Related: Practical 4D Construction Simulation Using Revit and Navisworks with Kenneth Flannigan Revit My first 4D simulation project was a hospital with more than 300 hundred tasks and it became really complicated to link all elements, mostly because of mismatches between them and the required time execution.Īfter several 4D simulation projects, a lot of practice and improvements on efficiency methods, and the use of Dynamo on the workflow, it's much easier to create 4D simulation that holds the characteristics required and can be created faster than ever before. ![]() That’s the main problem when doing it: the time schedule needs to have Revit elements and the model requires to have elements for all time schedule tasks. To create a 4D simulation, construction tasks and elements in the model need to be connected. 4D SimulationĤD simulation is the process of linking a time schedule with construction elements, so that it can easily give us an idea of how construction would be performed, tracked, and reported. The information presented in this article is the synthesis of 13 years of simulations from different projects to make 4D simulation a required task for all projects. We will cover several routine workflows so that all elements for any type of intelligent model are aligned, clean, and useful for project management, enabling us to link the model and time schedules with Navisworks in record time. With the approach outlined here, we will use the Dynamo player and Dynamo workflows with Revit 2021 to clean, manage, label, and even create a time schedule so 4D simulation can be easily created and the communication proposal facilitates model coordination and execution. Reasons can include problems in model coordination, time and element mismatches, time model execution availability, and more. ![]() 4D time simulations in Navisworks software for construction projects are often complicated BIM services to be used on a daily basis.
