A tapered extrude can be created from 2D objects, 3D polygons, and NURBS curves, circles, and arcs. (2D objects cannot be screen plane objects; change them to planar objects first. See Planar Modes of 2D Objects: Screen Plane and Layer Plane.)
This command easily creates wavy extrusions by entering a taper value of zero.The command also extrudes 2D objects into 3D objects with a defined taper. Use it to convert a single object or several objects at the same time. Once created, the height and taper can be edited in the Object Info palette.
The tapered extrude object height can be edited interactively with the Reshape tool; see Reshaping Extruded Objects and Solid Primitives for more information.
To create a tapered extrude:
1. Select the object(s) to turn into a tapered extrude.
2. Select Model > Tapered Extrude.
The Create Tapered Extrude dialog box opens.
3. Enter the Height (Z) of the extrude and the Taper Angle. A positive taper degree shrinks the object as it extrudes, while a negative taper degree widens the object.
Set a Taper Angle of 0 to create an extrusion with no taper.
4. Click OK to create the tapered extrude.
If a tapered extrude fails, the object reverts to the last known “good” value.
