Part Helix/fr

Description
La primitive géométrique crée une forme d'hélice définie par un rayon, un pas et une hauteur totale.



Utilisation
See Part Primitives.

Example


A Part Helix object created with the scripting example below is shown here.

Options
Un usage courant de la primitive hélice est pour la Création de vis en conjonction avec un profil fermé et le opération. Ce processus fonctionne essentiellement de la même manière dans l'Atelier PartDesign en utilisant l'outil.

Properties
See also: Property editor.

A Part Helix object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data
The object has the same attachment properties as a Part Part2DObject.


 * : The handedness, or direction, of the helix: or . The default is, meaning the helix turns counterclockwise as it goes up.


 * : The distance between two consecutive turns of the helix measured along its Z axis. The default is.
 * : The height of the helix. The default is.
 * : The start radius of the helix. The helix has a constant radius if is.
 * : The number of turns per helix subdivision. The default is, meaning each full turn of the helix is a separate segment. Use to suppress subdivision.
 * : The angle that defines of the outer shape of the helix. Valid range: . The default is . If it is the helix is cylindrical, else it is conical.

Scripting

A Part Helix can be created with the method of the document:


 * Where is the name for the object.
 * The function returns the newly created object.
