Separate

1. Create a polygon cylinder.
2. Change Subdivision Height to 3.
3. Look at the cylinder in the front view and change it to face mode.
4. Select the middle part and delete it. The separate two cylinders are still combined. You may change it to Object Mode and try to move them.
5. Select them and select Mesh > Separate. One cylinder is green and the other is pink. They are separated.

Combine

1. Create a polygon cube and duplicate it.
2. Select the above two polygons.
3. Select Mesh > Combine.
4. Try to move the polygons combined. They will move together.
5. Select the two polygons again.
6. To separate them, select Mesh > Separate. This time they are two independent polygons.

Create a polygon tool

1. Select Mesh > Create Polygon Tool.
2. Click the left mouse button to place the first point(or vertex) in the front view.
Maya places vertices on the ground place unless you snap them to existing geometry.
i just officially bought Maya 2008 so expect some very noob questions.
3. Click to place the next vertex. Maya creates an edge between the first point and the last point you placed.
4. Place the third vertex. A dashed edge connects the three vertices.
5. Place the fourth vertex. A dashed edge connects the four vertices again.
6. To close the polygon, place the last vertex. A dashed edge connects the five vertices again.
7. To complete the new polygon, press Enter.
It cannot form a plane this time.

    Press Delete to delete the last point you placed.
    Press y to start a new polygon.
    To switch to editing vertices, press Insert.

To add a connected polygon to an existing mesh

1. Select the polygon you want to append to.
2. Select Edit > Append to Polygon Tool.
     The border edges highlight and appear thicker.
3. Click the border edge you want to append to.
    The edge you select is the first edge of the new face. Arrows indicate the edge direction.
4. Click to place a vertex for the new polygon. You can also click another border edge to use it in
     the new polygon.
non-boundary edge?

To create a new polygon

1. Select Mesh > Create Polygon Tool.
2. Click to place the first vertex in the front view.
3. Click to place the next vertex.
4. Place another vertex.
5. Press Enter to finish the polygon.
    Press Delete to delete the last point you placed.
    Press y to start a new polygon.
    To switch to editing vertices, press Home or Insert.

Creating polygon primitives

http://www.cgonlinetutorials.com/tutorials/joy-stick.html

F can move objects to the center of the screen.

Create/ Polygon Primitives/ Sphere, Cube, Cylinder, Cone, Plane, Torus, Prism, Pyramid, Pipe, Helis, Soccer Ball, Platonic Solids

Interactive Creation: You can position and scale primitives as you create them using your mouse, without having to use transformation tools.

Exit on Completion: This option interacts with Interactive Creation. When Exit on Completion is turned on, you must select a primitive type again in order to create another primitive. When this option is turned off, you can interactively create multiple primitives of the same type, until you select another tool.
