A method, apparatus, system, and computer program product provide the ability to simulate a construction schedule. A first three-dimensional (3D) model and a schedule are acquired. The schedule includes activities for building the 3D model. Each of the activities is associated with model object(s) of the 3D model. A subset of the activities is selected based on properties of the activities. A first simulation appearance (of the model objects attached to the selected subset of activities) is defined. A second simulation appearance is defined for remaining/non-selected activities. The selected subset, the first simulation appearance, and the second simulation appearance are packaged into a playback profile that is capable of being applied to a second 3D model. A simulation of construction of the first 3D model (that is based on the playback profile) is played back.
