Aggregation Levels

How CAST Imaging organizes objects into levels from overview to detail.

Within any scope, objects are organized into levels. Levels let you start with a broad view and drill down to the detail you need.

The levels

Level What you see
Level 1 Very large groups — for example, one node per technology family
Level 2 Smaller groups — for example, one node per application layer
Level 3 Components or subsystems
Level 4 Packages or modules
Level 5 Individual classes, procedures, or similar objects
Objects level The same as Level 5 but with full drill-down capability and contextual actions

Not all levels are available in every scope. The Transaction scope starts at Level 4, for example.

How to move between levels

  • Double-click a node to drill down to the next level.
  • Shift + double-click on empty space to go up one level.
  • Use the level selector in the Investigation panel to jump directly to a level.

Large node behaviour

If a node at Level 5 contains more than 500 child objects, CAST Imaging shows a search dialog instead of loading everything at once. Use the dialog to select the specific objects you want to see.
