Using the Sequence Editor 

The sequence editor lets you manage and simulate the following types of actions:
  • moving objects (part, camera, ...) 
  • graphic attributes ( show/hide, colors, transparency)

You can also manage time with Gantt chart.

The Edit Sequence dialog box comprises two tabs:

Using the Edit Action Tab

Add Actions
Select an action in the Action in session list and click the Add button . 

The action is added in the Action in Sequence list.

Remove Actions
Select an action in the Action in session list and click the Remove button . 

The action is removed from the Action in Sequence list.
  If you multi-select actions in the Action in session list and click the Add button, the actions are added in simultaneous mode.

Customize the Action Add Mode Settings
Create last step and add option: creates a last step and adds the selected action into it.  This option is the default for the Action add mode settings.  This option works in consecutive mode.
 
Add in last step option: lets you add an action in last step in simultaneous mode.
 
Iterative create last step and add option: lets you add the actions in consecutive steps (1-2-3...)
 

Sequence Actions
The method of sequencing actions depends on whether you want the actions create in simultaneous or consecutive mode.
  • For consecutive mode:
    • Move up:  moves up a selected action 
    • Move down:  moves down a selected action
  • For simultaneous mode:
    • Merge up: merges the selected action up
    • Merge down: merges the selected action down
  Remember you can combine the two modes within the same sequence.

Customize the Action Duration
  • Action duration: the numerical field lets you enter a specific duration for an action (this capability enables to simulate the same action with a different time scaling).
 
  • Reset duration lets you reset the selected action to its intrinsic duration
 
  You can enter a specific duration for all action types except visibility actions which are instantaneous (i.e., duration=0)
  • Action delay: lets you delay the starting time of an action (i.e., it is now possible to overlap two actions)

For instance, two tracks within the same sequence step can be synchronized, in order to achieve passing by specific way or via points simultaneously.

For all actions contained in the sequence, the delay is a time attribute, just like their duration. It means the action will start with respect to the specified delay with the theoretical beginning of the step, which the action belongs to. Valid delay values are zero or positive.

When actions appear in the Action in sequence list, they are scheduled in steps and their duration and delays are displayed.
  To apply a delay to an action or modify a delay, select the required action in the Action in session list and enter a value in Action delay.

Using the Edit Analysis Tab

Add Interferences or Distances
Select an analysis in the Analyses in session list and click the Add button.

The action is added in the sequence list.

Remove Interferences or Distances
Select an analysis in the Analyses in Sequence list and click the Remove button.
You can add existing interferences or distances or create them on the fly (in this case they are automatically displayed in the Analyses in session list

Set the Clash Detection Mode
  • Set all inactive option: (default mode) as you simulate your sequence, the detection is set to off, the interferences and/or distances defined in your sequence are not taken into account
  • Set all active option: as you simulate your sequence the detection is set to on, the interferences and/or distances defined in your sequence are taken into account
  • Set all stop option: as you simulate your sequence, the detection is set to stop (on collision), the simulation stops when an interference defined in your sequence is detected. The distances defined remain active.

Editing Actions and Analysis
  Double-click actions, interferences, or distances to display the dedicated editor. Perform the required modifications. The modifications are automatically taken into account in the Edit Sequence dialog box.
 

Player Pop-up Toolbar
The Simulation Player pop-up toolbar appears when the Edit Sequence dialog box opens.  Only the time mode is available for sequence editing. 

When you play the sequence, the action being performed is highlighted in the Edit Sequence dialog box. If you do not want the actions highlighted, clear the Highlight the Simulated Action(s) check box. 

If you have a delay as part of the sequence, you may see some overlap in the highlighting.
