up to the opening.

Select the Mirrored extent check box to extrude
the profile in the opposite direction using the same length value as
the one defined for the first length.

By default, Normal to profile is selected,
meaning that the profile is extruded normal to the sketch plane.
Click the Draft tab to define a draft angle.
Set Intrinsic to feature to define the draft
behavior.
Specify the draft angle in the Angle box.
The default neutral element (defines a neutral
curve on which the drafted face will lie) is the
profile plane. The other possible neutral elements can be:
- Ceiling
- Opening
- Plane/Surface
For the purposes of our scenario, keep the default
neutral element.
Click Preview.

If you want to fillet edges, click the Fillet
tab. Selecting the Lateral radius check box enables you to
fillet lateral edges. Then, you merely need to set the radius value
of your choice.
Select the Ceiling radius check box to fillet
the cylinder's top.
Enter 3.5mm to define the ceiling radius value.

If the boss is to be shelled, you can select the
Constant wall thickness check box which propagates the fillets
into the shell, thus maintaining a constant wall thickness.
You can control
whether the wall is constructed inside or outside of the selected
profile. The default is an inside wall thickness. To define the wall,
you can set one of the two options available from the Type
drop down list:
-
Use body thickness: the
boss wall thickness is that of the active shelled body thickness.
-
Enter thickness: simply enter
the value you want. After this option is selected, the value
box becomes available. Wall thickness values can only by
positive values.
For the purpose of our scenario, set Enter thickness
and enter 8mm in the Thickness value box.
Click OK to confirm and create the boss.
Boss.X is added to the specification tree in the Solid
Functional Set.x node.
