Overview
Each item in a station can be moved to achieve the required layout, so you first have to
determine its selection level. The selection level makes it possible to select only specific types
of items, or specified parts of objects.
The selection levels are curve, surface, entity, part, mechanism, group, target/frame and path.
The target/frame and path selection can be combined with any of the other selection levels.
Objects may also be grouped together as component groups, see Component Group on page
234.
