A SelectionSet represents the named scene node selection sets in the Named Selection Sets drop-down list in the 3ds max toolbar. Also see SelectionSetArray Values. SelectionSet values are mappable.
Constructors
selectionSets[<set_name>] -- set by string or name value
selectionSets[<index>] -- set by order in drop-down list
Operators
<selectionset>[<integer>] -- retrieve nth object in set
Properties
<selectionset>.center : Point3, read-only
Returns center of bounding box of all objects in set.
<selectionset>.max : Point3, read-only
Returns maximum corner of bounding box.
<selectionset>.min : Point3, read-only
Returns minimum corner of bounding box.
<selectionset>.count : Integer, read-only
Returns number of objects in set.
Note: Unlike ObjectSet, you cannot use SelectionSet as the root of a pathname.
The order of sequencing is consistent in a stable scene but somewhat arbitrary - it depends on how 3ds max stores its object hierarchy internally which is effected mostly by order of additions and deletions to and from the scene.
