To taper a solid or NURBS surface:
Click the Deform tool from the 3D Modeling tool set, and then select Taper Solid mode.
Symmetric mode is selected by default; a four-way arrow feedback graphic displays around the cursor, and an equal amount of taper applies to both the drag direction and its perpendicular direction. If an asymmetrical taper is desired, deselect Symmetric mode on the tool bar; a two-way arrow feedback graphic displays, and the taper applies only to the drag direction; its perpendicular direction has no taper.
The Symmetric mode status can also be changed at any time during the operation.
As you move the cursor over 3D objects, they are highlighted to indicate they can be modified. Click to select the solid or NURBS surface.
Shift-click to select more than one object.
A four-way or two-way arrow feedback graphic displays around the cursor. Position the arrow graphic at the desired taper center, and click.
The arrow graphic displays only when an object is selected. To position the arrows as desired, you may need to activate a specific plane using the Active Planes list from the View bar.
The taper center can be located away from the object being tapered.
The arrow graphic remains at the click point, and the taper axis line appears. As you move the cursor, the arrows rotate to indicate the direction of the taper, and the taper reference line previews the starting point for the taper. Click to place the reference line.
As you move the cursor, the taper ratio line tracks the cursor, and a preview of the tapered object displays.
To taper to a precise ratio, press the Tab key and enter a positive number in the Data bar. The original shape ratio is 1; numbers below 1 taper inward, while numbers above 1 taper outward. Press Enter to display a preview of the taper.
Click to complete the operation. The result is a generic solid object.
