Components intersection

Need a tool to define and export list of all components (or groups) intersections,
Should my model show a tank divided into many smaller tanks, for each of those tanks need a list of all tanks that are adjacent to this one.
Would be great if one can help.

It sounds like you need to use the Outliner to identify all components and groups in your model.

To get to the Outliner tab click on Window > Default Tray > Outliner. Then make sure that the Default Tray is visible at the side of your screen and open the Outliner tab.
