• helix to add material
  • parallel
  • tapered
• helix to remove material

In creating a helix you will:

• create one or more new sketches
• create a line to be used as an axis
• create a valid profile to use for the profile of the helix
• generate a helix

Helix to add material

To create a helix to add material

• create a new sketch to contain the axis - name the sketch axis

• Create a new line on the axis sketch to represent the axis of the helix

  • NOTE the length of the line will determine the length of the helix

• create a new sketch to contain the profile of the helix - name the sketch profile

• on the profile sketch, draw a valid profile

• apply constraints as required to the:

  • size of the profile and

  • the distance from the axis to the profile

• from the Features menu select Sweep profile then along helix

• in the dialog box

  • ensure that the Pro Desktop has selected the correct sketches for the profile and axis

  • enter the taper angle if required

• click and drag the yellow handle to generate a pitch OR

  • specify the pitch exactly in the dialog box

• click OK to create the helix

Helix to remove material

To create a helix to remove material from a model

• create new sketches for the helix axis and profile

• create a sketch for the parent material model

• create the helix axis on the axis sketch

• create the helix profile on the profile sketch

• create the parent material profile

• apply constraints as required to the:

  • size of the helix profile

  • the distance from the helix axis to the helix profile

  • the size of the parent material profile

• extrude the parent material

• from the Features menu select Sweep profile then along helix

• in the dialog box

  • ensure that the Pro Desktop has selected the correct sketches for the profile and axis

  • select subtract material

• click and drag the yellow handle to generate a pitch

• if necessary, specify the pitch exactly in the dialog box

• click OK to create the helix
