Part Helix

Description

The [ Part Helix geometric primitive creates a helix shape, defined by a radius, a pitch, and a total height.

A common usage for the helix primitive is for creating screw threads in conjunction with a closed profile, and the Sweep operation. This process works essentially the same in the PartDesign Workbench by using the [ PartDesign Additive pipe tool.

Usage

  1. Switch to the Part Workbench.
  2. The Create Primitives dialogue can be accessed several ways:
    • Pressing the [ Primitives button located in the Part toolbar.
    • Using the Part → [ Create primitives → Helix entry in the Part menu.

Parameter

  • {{Parameter|Pitch:}}The pitch corresponds to the space between two consecutive "turns" of the helix measured along the main axis of the helix.

  • {{Parameter|Height:}}The height corresponds to the overall height of the helix measured along the main axis of the helix.

  • {{Parameter|Radius:}}The radius corresponds to the radius of the circle built by the helix by viewing the helix from the top or bottom.

  • {{Parameter|Angle}}: Per default the helix is built on a imaginary cylinder. With this option it is possible to build the helix on a imaginary cone. This angle corresponds to the angle of the cone. The value must be comprised between 0 and +90 deg.

  • {{Parameter|Right-handed or Left-handed:}}This parameter specifies the handedness of the helix.

Location

  • {{Parameter|X:}}The main axis of the helix will be translated along the x axis of the value you indicate in this field.

  • {{Parameter|Y:}}The main axis of the helix will be translated along the y axis of the value you indicate in this field.

  • {{Parameter|Z:}}The main axis of the helix will be translated along the z axis of the value you indicate in this field.

  • {{Parameter|Direction:}}Per default the main axis of the helix is the z axis. Here you have the possibility to edit the main axis of the helix. If you select the parameter "user defined..." , you will be invited to indicate the main axis of the helix by entering the coordinates of its vector.

  • {{Parameter|3D View:}}allows you select center in the 3D view

Options

Properties

Once you have created the helix you have the possibility to edit its parameters.
