How to create Helical Sweep in Pro/E- Constant & Variable

Helical Sweep:
   The Helical Sweep command extrudes a section along a helical trajectory.For this command you have to define a trajectory that will specify the shape and height of the helix, a pitch value and the cross section of the helical feature. this command is mainly used to create helical springs and threads.




The following task explain how to create a spring using the Helical Sweep
1. Open a new Part file Helical Sweep.prt
2.Click Insert > Helical Sweep > Protrusion... The PROTRUSION: Helical Sweep dialog box and the Menu Manager appear.
3. The PROTRUSION dialog box initially prompts ATTRIBUTES to define the helical geometry.

Constant: Defines a constant pitch for the helical geometry
Variable: You can specify a variable pitch which is defined by a graph.
Thru Axis: The cross section lies in a plane that passes through the axis of revolution.
Norm To Traj: The cross section is oriented normal to the trajectory.
Right Handed: This option is used to create a helical feature in which the section is swept in counter clockwise direction from the start sketch.
Left Handed: This option is used to create a helical feature in which the section is swept in  clockwise direction from the start sketch.

4. For our context, specify Constant pitch, Thru Axis and Right Handed sweep.Click Done in the Menu Manager sfter specifying the above options.
5. The PROTRUSION dialog box now requests you to sketch the sweep profile. The Menu Manager prompts you to select the plane to sketch the sweep profile.
6.Select the FRONT plane as the sketching plane and specify the direction of viewing. You will now enter the sketcher environment.Specify the references.
7. Sketch the sweep Profile and centerline.
8. Complete the sketch.Now the command prompts for the pitch value.Enter the value and then click ok
9. Construct the cross-section of the sketch.
10. Click continue with current session icon.
11. Click ok in the PROTRUSION dialog box to complete the geometry.
12. The command Helical Sweep > Cut... removes the material as the section is swept around the path.This command is useful for creating threads. The attributes and the procedures are the same as explained in the Helical Sweep > Protrusion... Command.
