To Add a Taper to an Extrude Feature
You can add a taper to an extrude if the section of the feature is a closed loop. You cannot taper an extrude if is selected to add a thickness. The Extrude tab must be open to perform this procedure.
1. Click the Options tab.
2. Select the Add taper check box.
3. Type a value for the taper angle from -89.9° to 89.9° in the box.
You can enable or disable the Add taper check box on the Options tab by setting the enable_tapered_extrude configuration option. Set the option to yes to enable the check box, or to no to disable it.
