In this lesson, you will use the Symmetry modifier to create a corner cabinet.
Set up the lesson:
Create a corner cabinet:
Hide Selection, so only the 24-inch cabinet is visible. 
Select the cabinet and Shift+drag the object on its X axis to the right.
Object group, choose Copy, and in the Name field, type LoCab_Corner, then click OK. (If you continued working from the previous lesson, Offset mode is already active.)
Move/Rotate/Scale group, click Affect Object Only. This lets you move the object but not its pivot. In the next step, you will move the object so that its pivot point is at the cabinet’s back right corner.

Polygon Modeling panel, click Modify Mode, then activate 
A corner cabinet is typically 36 inches wide, so next you will expand the width of the cabinet.
Widen the cabinet and add the Symmetry modifier:
Polygon Modeling panel, activate

Polygon Modeling panel, click 
The modifier gizmo displays in the viewport, oriented in the direction of the cabinet’s pivot point.

Mirror Axis group, turn on Flip. 
3ds Max flips the cabinet about its X axis.

Throughout this tutorial, you used a number of modeling tools on the Graphite Modeling Tools ribbon to create a set of kitchen cabinets. While these tools are also available from the Command panel, the ribbon gives you faster access, in context, as you need them.
This tutorial only scratched the surface of the many ways in which the ribbon can be used for editing mesh and polygonal objects. For a full description of the ribbon tools, consult the 3ds Max help.
