#### ThicknessData.get\_element\_indices(visible=None, selected=None)

Get element indices (ACP internal element numbers starting from 0) of plot

- **Parameters:**
    - visible: Object(s) defining visible scope
    - selected: Selected object(s) for ply-wise evaluations.
- **Returns:**Resulting array with element indices from the intersection of 
    - data\_scope of plot
    - visible\_scope defined by visible
    - selection\_scope defined by selected

Indices are returned independent of update status of plot, but only if results for the current plot configuration are available, else an empty array is returned.

**Examples:**: Get element indices for current plot with visible scope set to element set “All\_Elements” and with ply1 and ply2 selected:

```default
&gt;&gt;&gt; eis = my_plot.get_element_indices(visible=db.active_model.element_sets['All_Elements'], selected=[ply1, ply2])

```

   
 Get element indices for current plot with visible scope equal to all objects visible in current scene:   
 ```default &gt;&gt;&gt; eis = my_plot.get_element_indices(visible=db.active_model.active_scene.active_set.entities) ```
