Merge Objects
Modify > Merge
Objects
Description:
The Merge Objects (Modify > Merge Objects) command
makes all selected objects into a single object. It is similar to a
Group command in that it has has no effect on the geometry of the merged
objects, but rather changes the way the program represents that
geometry internally.
Notes:
-Merge Objects is particularly useful for operations such as booleans
or the Append Polygon Tool which require
that a specific number of objects be selected, since you can merge
several objects to make one object.
-Merge Objects only works in object selection mode.
