Creating spiral stair with maya is very simple, we just rotate the numbers of object’s copies on appropriate angle and we get spiral steps of being experimented object on one click.
Just create a polygon cube on the origin then go to the duplicate object command and from options change the angle of being copied object according to your need and then increase the copies according to your requirement as well. That’s it. Now click the button duplicate and you will find a sequence of objects in an array. Changing angle of object, increasing the numbers of copies and making them the duplicates of object is a well known way of AutoCAD users to make arrays of objects. We actually make an array around the axis by putting some angle values to its duplicate copies.
