ItemType (Optional)

Type: ETABS2015 eItemType
This is one of the following items in the eItemType enumeration:

• Object = 0
• Group = 1
• SelectedObjects = 2

If this item is Objects, the assignment is made to the frame object specified by the Name item.

If this item is Group, the assignment is made to all frame objects in the group specified by the Name item.

If this item is SelectedObjects, the assignment is made to all selected frame objects and the Name item is ignored.
