Grouping Objects using Multipoint and Collection Object Types
The Multipoint and Collection object types allow you to group multiple objects into a single object. One
way to create multipoints and collections is by using the Combine command (on the Objects menu, click
Combine). These object types aid in the translation and live access of other GIS data formats, such as
ArcView Shape Files, and are more compatible with GIS standards. This is particularly useful for sharing
maps with others using different software.
A Multipoint object consists of a number of points that have been grouped into a single object. The
Multipoint object displays in a Browser window as a single record, and all the points within the object
have the same symbol. One method you can use to create a multipoint object is to select a group of
point objects and combine them.
A Collection object consists of multipoint objects, zero or one polyline objects, and zero or one region
objects that have been grouped into a single object.
MapInfo Professional automatically converts homogeneous Collection objects to a more specific type,
for example, a Collection object that contains only polylines is automatically converted to a multi-polyline
object.

Collection Object Types in the Help System.
Creating and Manipulating Objects
The operations in this section do not make use of a target object to perform analysis or data aggregation.
These tasks use selections to create new objects so that you can perform further mapping operations
on those objects. The results of the operation are placed in the editable layer. The original objects remain
unchanged.
