How to Combine Multiple objects in Maya Using Boolean and Bridge Tools

It is so easy to Merge or combine different objects in Maya , So first create two Objects ( i took a Sphere and an a Cube )

First press F3 on your keyboard for Polygon mode
Now select both the objects ( first select the Cube and then hold shift select Sphere )  and under Mesh click on Boolean . In Boolean we have three different Option 1.Union 2. Difference and 3. Intersection , first click on Union .

Union means it will combine objects so by using this tool you can combine multiple objects

The next tool is " Difference " , by using this tool we can differentiate multiple objects , first select the Cube and hold shift then select the Sphere , now select the differentiate .

There is another tool which can combine Objects , that is " Bridge " tool .
Before applying this to your objects , first you need to Combine the objects which you want to Bridge.

Now select equal number of faces on both objects ( in my case i have selected 4 faces on the right object and 4 on the left side )  and then under " Edit Mesh " select the " Bridge : option.
