About Join, Split, and Mirror Track Operators

Join, Split, and Mirror Track operators can be used to create new Tracks as output from existing Tracks.

Using Track Operators to Output New Tracks

Join Track Operator

You can join two or more Tracks in Workplan, Model Scenario Results (MSR), and Resource modes.

Join Operator Definition



Types of previous Tracks possible:

  • Precedence constraints: End-Start
  • Synchronization links: Start-start, End-start, and Start-Start with delay

Types of following Tracks possible:

  • Precedence constraints: Start-End
  • Synchronization links: Start-End and End-End

Join Track in Work Plan Mode

Only the Tracks from the same operation can be joined.

If the Keep Original option is selected:

  • The new joined Track is appended last in the operation sequence and a precedence constraint is created with the last ordered Track under the operation.
  • The original Tracks remain under the operation with their defined constraints.

If the Keep Original option is not selected:

  • The previous Tracks on the first Track are applied as previous Tracks on the joined Track.
  • The following Tracks on the last Track are applied as following Tracks on the joined Track.
  • All the original Tracks are deleted with their existing constraints (no automatic reconnection for the deleted Tracks).

Below are some examples of Join Result (automatic constraints management) in Workplan mode when the Keep Original option is not selected.











Join Result in MSR and Resource Modes

If the Keep Original option is selected, the result of Join is as follows:

  • All the original Tracks remain in the sequence with their defined constraints.
  • The joined Track is added under excitation. No instance of this new Track is created and added in any of the existing sequences.

If the Keep Original option is not selected, the result of Join is as follows:

  • All the instances of original Tracks in different sequence are deleted with their constraints. (Automatic reconnection holds true in this case.)
  • The joined Track is added under excitation. No instance of this new Track is created or added in any sequence.

Split Tracks Operator

You can split a Track either by selecting a Trajectory point (T-Point) on the original Track or a trajectory segment in Workplan, Model Scenario Results (MSR), and Resource modes.

Split Operator Definition



Types of previous Tracks possible:

  • Precedence constraints: End-Start
  • Synchronization links: Start-start, End-start, and, Start-Start with delay

Types of following Tracks possible:

  • Precedence constraints: Start-End
  • Synchronization links: Start-End and End-End

Split Track in Work Plan Mode



If the Keep Original option is selected (picture above):

  • The new split Tracks are connected through a precedence constraint.
  • Split Track.1 is connected through a precedence constraint with the last ordered Track under operation.
  • Original split Track continues to exist under operation with its defined constraints.



If the Keep Original option is not selected (picture above):

  • The previous Tracks on the candidate split Track are applied as previous Tracks on the first split Track.
  • The following Tracks on the candidate split Track are applied as following Tracks on the second split Track.
  • The original candidate split Track is deleted along with their existing constraints.

Split Result in MSR and Resource Modes

If the Keep Original option is selected:

  • The original Track remains in the sequence with its defined constraints.
  • The split Tracks are added under excitation. In MSR mode, no instance of these new Tracks is created or added in any sequence.

If the Keep Original option is not selected:

  • All the instances of the original Track in different sequences are deleted with its constraints.
  • The split Tracks are added under excitation. In MSR mode, no instance of these new Tracks is created or added in any sequence.

Mirror Track Operator

You can create a mirror image of a Track along a line or plane in Workplan, Model Scenario Results (MSR), and Resource modes.

In Workplan mode, mirror Track is added after the last ordered Track under operation sequence with a precedence constraint with the last Track available under operation before mirroring.

In MSR mode, no new instance of the mirrored Track is created or added in any of the existing assembly sequences.

In MSR and Resource modes, mirrored Track is added only under Excitation.
