Applying Boolean Set Operations
Select an object.
Click 
and then a second object to merge the
two objects. This differs from a union in that it does not create any new faces or points,
but simply creates a single object from the two. Also, all material information is
retained.

Click 
and then a second object to create a
new object from the union of the two objects.
Click 
and then a second object to
create a new object from the intersection of the two objects.
Click 
and then a second object to
subtract the first from the second.
Click 
and then a second object to blend the
two objects. This can be a time consuming task.
Click 
and then a second object to create a
single object with a bridge between the two objects. Options are available for the bridge
effect by right-clicking. This can be a time consuming task.
It is also useful to triangulate objects prior to Boolean set operations if an object has been deformed, point edited or face edited. This will result in faster and more accurate results.
