8.11.1.2.  Focus

The primary goal of the focus is to reduce the amount of visible elements and dependencies so that specific aspects of the software system can be analyzed more easily. Several focus operations are available that can be applied to 1 or more elements or dependencies. To apply a focus operation simply select elements or dependencies and choose a focus operation from the context menu.

Remove From Focus

The simplest form of reducing the amount of visible elements/dependencies is to remove elements/dependencies from the view, that are currently not of interest. Select the elements/dependencies, right click to bring up the context menu and choose 'Remove From Focus'.

Set Focus

Another way of reducing the amount of visible elements/dependencies is to explicitly focus elements/dependencies. Select the elements/dependencies, right click to bring up the context menu and choose 'Set Focus'.

The transitively options also let you include indirectly connected nodes per incoming/outgoing dependencies.

NOTE: If only dependencies are selected only the 'Dependency Types' are available and not the 'Nodes' section.

Add To Focus

Select elements/dependencies, right click to bring up the context menu and choose 'Add To Focus' to potentially extend the visible elements dependencies.

When not all children of a selected element are currently visible the user can decide to include the not visible children as well by selecting the 'All Children' option.

Re-Adding Not Visible Elements

Once an element is removed from the view it is still possible the locate the element using the Find dialog (context menu 'Find Elements...') select it and use 'Reveal With Focus...'.

Clear Focus

When you have an applied focus, the context menu will show the 'Clear Focus' entry to clear the current focus.
