4D planning

The Project Timeline lets you explore how a project changes over time. Planned objects are shown across a date range, so you can review which parts of a scenario are present at a selected moment and communicate the intended phasing.

Set planning dates for the objects or project elements you want to include. Open Project Timeline and use the date slider to move to a point in the schedule. The 3D view updates to reflect the project at that time. Use playback to step through the schedule and the speed control to adjust playback.

If the timeline does not show the expected changes, check that the relevant objects have planning dates and that the selected date range includes them. Timeline output depends on the dates and project data entered; it is a way to explore and present phasing, not a construction schedule or critical-path calculation.
