Part Helix/it

Description
This page explains you, how to edit basic parameters of an helix. Once you click the icon CreatePrimitives and then the helix icon  in the drop down menu, you will see following menu to edit parameters for the creation of the helix. Once you have edited all the parameters click the button "create" to draw the helix.

Parameter

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

Location

 * The main axis of the helix will be translated along the x axis of the value you indicate in this field.
 * The main axis of the helix will be translated along the y axis of the value you indicate in this field.
 * The main axis of the helix will be translated along the z axis of the value you indicate in this field.
 * 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.
 * allows you select center in the 3D view

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