Part CreatePrimitives

## Description

The 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 operation. This process works essentially the same in the PartDesign Workbench by using the tool.

## Usage

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

#### Parameter

• Pitch:The pitch corresponds to the space between two consecutive "turns" of the helix measured along the main axis of the helix.
• Height: The height corresponds to the overall height of the helix measured along the main axis of the helix.
• Radius: The radius corresponds to the radius of the circle built by the helix by viewing the helix from the top or bottom.
• Angle: Per default the helix is built on a imaginary cylinder. With this option it is possible to build the helix on a imaginay cone. This angle corresponds to the angle of the cone. The value must be comprised between 0 and +90 deg.
• Right-handed or Left-handed: This parameter specifies the handedness of the helix.

#### Location

• X: The main axis of the helix will be translated along the x axis of the value you indicate in this field.
• Y: The main axis of the helix will be translated along the y axis of the value you indicate in this field.
• Z: The main axis of the helix will be translated along the z axis of the value you indicate in this field.
• 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.
• 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.

 The parameters in this menu are similar to those described above. Base Placement: allows you to move or rotate the helix Angle:
