Exercise 5.3.1: Creating a 4D Simulation

In this exercise, students will learn how to:

Link a schedule file to the TimeLiner tool and generate the hierarchy of tasks.
Create selection sets and search sets to facilitate linking model elements to the schedule tasks.
Specify simulation settings and run a 4D simulation.

Continuing from the point where the tutorial left off, creating additional search and selection sets to select groups of model objects between Level 2 and the Roof level. Each set should contain the elements to be mapped to a specific task in the construction schedule.
Use the TimeLiner tool to attach the sets of objects to their associated schedule tasks.
Run a 4D simulation of the construction schedule. Modify the playback duration and interval size to achieve the desired visual effect for effectively sharing the simulation with others.

Exercise 5.3.2: Identifying Time-Based Clashes

In this exercise, students will learn how to:

Reveal a time-based clash by linking a clash test to the project schedule.
Add schedule tasks to accurately reflect the existence of temporary construction objects, and attach model geometry to that task.
Run a time-based clash test to confirm the elimination of the time-based clash.
Run a 4D simulation that includes the appearance and disappearance of temporary object to the project.

Use the project schedule to determine the date by which the material lift must be removed in order to avoid interfering with the installation of the building stair.
Modify the schedule task linked to the materials lift so that it reflects the required installation and removal dates.
Perform a time-based clash test between the Construction_Equipment and the Architectural_Shell models to confirm that a clash no longer exists between the materials lift and the stair. Be sure to link to the TimeLiner when you run this test in the Clash Detective tool.
