To change the height of a peak on the wall:
In a 3D view, select the wall to reshape.
Click the Reshape tool from the Basic palette, and select Reshape 3D Walls mode.
Position the cursor over one of the handles on the ends of the top or bottom of the wall, and click.
When the cursor is over a reshape handle, the standard arrow cursor changes into a double-headed, unfilled arrow.
Move the cursor to adjust the wall.
Click at the desired location.
Changing the height of a wall peak does not change the height of the wall.
