How do I create a polygon with any number of sides?

[Anonymous]

I want to create hexagons and octagons but I have no idea where to start.

GO INTO SKETCH MODE,  PRESS THE DOWN ARROW UNDER THE DRAW RECTANGLE.

  AT THE BOTTOM OF THE DROP DOWN LIST IS POLYGON OPTION..  SHOULD BE SELF EXPLANITORY FROM THERE

Create a polygon cyclinder and set it to the number you want. 

Hexagons = 6

Octagons = 8

EDIT: Select the small square beside Cynlinder in the create>Polygon>cylinder menu
