Now that our table model is complete, let's create a sheet in Maya to decorate it. We can duplicate the table's top itself and make it thinner to create a sheet. Let's do it.

When you duplicate an object in Maya by pressing Ctrl+d or by choosing Duplicate from the Edit menu, the object that get's created won't have the construction history associated with it. Here we need the construction history to be duplicated along with the object, because we are going to modify some attributes of the duplicate object to make it suitable to model a sheet.

For that, Maya provides us with a special Duplication. Select the table top and click on the small box beside the Edit > Duplicate Special item in the menu. Please make sure that you click on the box next to the menu item, as shown in the image. This will pop up a Duplicate Special Options dialog box in Maya. In that dialog box you will see a check box reading 'Duplicate Input graph'. Check it and click 'Duplicate Special'. This will create a duplicate of the table top with construction history also duplicated and associated with it. Move the duplicated object slightly above the table.
