Threaded Shape
Insert 
Features (Part Level)
Use this command to create
a threaded shape feature by revolving a closed profile about a cylindrical
face and along its linear axis and direction. This command can be used
to make thread features or any other shape that is revolved in a linear
direction.
The required inputs include the feature type (add or remove), the cylindrical face, the thread profile, the number of turns and the distance per turn. Optionally, you define the revolve direction, spiral direction, lead in/out options and lead in/out radius.

Select the feature type icon. For
the Add, Remove
and Intersect types, the topology
of the active part will be altered by the feature created. The
Base option is automatically selected
if the active part has no shape geometry. A
separate base feature will be created. Base
features are used to define the initial basic shape of a part.

Face - Select the cylindrical face on the stock.
Profile - Select the profile for the thread. You can select a sketch, curves, edges or a curve list. You can also right-click and make a curve list using the input options.
Turns - Specify the number of turns.
Distance - Specify the distance along the axis for each turn. A positive distance will be measured in the direction of the axis arrow.
Revolve clockwise - Check this box to revolve the thread clockwise about the axis of the cylindrical face
Reverse spiral direction - Check this box to reverse the spiral direction of the thread.
Lead in/out - Use this option to specify where the lead in/out is to be located. Select None, Start, End or Both ends.
Radius
- If a Lead in/out is selected (see above), specify the radius
of the transition. This determines a pivot point for the lead in/out and
contributes to the shape of the lead in/out transition. Skip this option
if no lead in/out is specified.
For lead in, the pivot point radius is measured from the point on the
profile closest to the axis of rotation. For lead out, the point on the
profile farthest away from the axis is used.
