PartDesign Revolution/fr

Introduction
Cet outil produit un solide par révolution d'une esquisse ou d'un objet 2D sélectionné autour d'un axe donné. Pour toutes les explications suivantes de cette commande, l'esquisse en exemple ci-dessous sera utilisée :

Utilisation

 * 1) Sélectionner une esquisse.
 * 2) Cliquer sur le bouton.
 * 3) Définir les paramètres de la révolution (voir section suivante).
 * 4) Cliquer sur OK.

Options
Lors de la création de la révolution, la vue combinée bascule automatiquement à l'onglet Tâches, qui affiche le dialogue « Paramètres de la révolution ». Plusieurs paramètres permettent de définir comment l'esquisse sera révolutionnée.

Axis
This option specifies the axis about which the sketch is to be revolved. Currently, only the horizontal or vertical sketch axis can be selected here. But in the Properties table, an arbitrary axis can be defined. Base is a point through which the axis goes. The axis option itself takes three arguments, which are passed as numbers to either the x, y, or z boxes in the tool. Adding a value of 1.0 to only one of the boxes will cause the tool to make the revolution about that axis. Example revolutions 1, 2 and 3 in the examples section demonstrate scenarios where the example sketch is revolved about either the x or the y axis. Adding a non-zero value to more than one of the axes will cause the part to be revolved by a weighted amount in each axis. e.g. an x value of 1 and a y value of 2 will mean that the revolution about the y-axis is twice as strong as that about the x. This is fairly difficult to comprehend, Example Revolution 4 shows an example where more than one of the boxes has a non-zero value.

Angle
This controls the angle through which the revolution is to be formed, e.g. 360° would be a full, contiguous revolution. The images in the examples section demonstrate some of the possibilities with specifying different angles. It is not possible to specify negative angles (use the Reversed option instead) or angles greater than 360°.

Symmetric to plane
The revolution will extend half of the specified angle in both directions from the sketch plane.

Reversed
The direction of revolution will be reversed.
