Synchro 4D – Dates to Use in 3D Window

Free
By Daria Kosmala |

Brief/Background

When we visualize our Synchro 4D model in 3D Window we can choose following dates to use in active 3D window: 

  • Best
  • Actual
  • Planned
  • Baseline
  • Proposed
  • Late dates

Dates to Use

Let’s review each option

1. Best

To begin with, the Synchro 3D window shows 4D simulation of our current schedule, a combination of actual + planned dates (past + future).
If the project hasn’t started, Best = Planned (all tasks are in the future from data date).
This is default Dates to Use setting.

2. Actual

In this case 3D window will show 4D simulation of completed and ongoing tasks, up to data date. In simple words: we see only what has been done (past). This option is applicable only when construction is in progress, and we can use it to compare actual status to initial schedule (baseplan)

3. Planned

In this case, 3D window will show 4D simulation of remaining tasks, starting from data date. In simple words: only what will be done (future).
If the project hasn’t started, Planned = Best (all tasks are in the future from data date).

4. Baseline

In this case, 3D window will show 4D simulation of saved baseline, which might be our Baseplan or Scenario. This option is applicable only if we have created at least one baseline.

Baseline A
Single Baseline

In case we have created more baselines, we choose, which one we want to show

Multiple Baseline

This option is used to compare actual progress to initial schedule (baseplan) or alternative construction scenarios

5. Proposed

In this case, 3D window will show 4D simulation of a temporary state of the un-rescheduled schedule but after implementing changes; proposed dates are used by planners only during the planning phase.

6. Late Dates

Finally, 3D window will show 4D simulation of tasks using their float to maximal extent – a state of a schedule with maximum "delay”; late dates are used by planners.
