Draft BSpline/fr

Description
The BSpline tool creates a B-Spline curve from several points in the current work plane. It takes the linewidth and color previously set on the Tasks tab. The BSpline tool behaves exactly like the Draft Wire tool.



Utilisation

 * 1) Pressez le bouton, ou pressez les touches  puis.
 * 2) Cliquez le premier point dans la vue 3D, ou tapez les coordonées.
 * 3) Cliquez un point additionnel dans la vue 3D, ou tapez les coordonées
 * 4) Pressez les touches  ou, ou double-cliquez le point suivant, ou cliquez sur le premier point pour finir ou fermer la . Si la  est fermée, elle peut aussi être une face, même si elle paraît comme une wireframe (fil).

Options

 * Press or the  button to finish the spline, leaving it open
 * Press or the  button or click on the first point to finish the spline, but making it closed by adding a last segment between the last point and the first one.
 * Press, or  after a point to constrain the next point on the given axis.
 * To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component.
 * Press or click the checkbox to check/uncheck the  button. If relative mode is on, the coordinates of the next point are relative to the last one. If not, they are absolute, taken from the (0,0,0) origin point.
 * Press or click the checkbox to check/uncheck the  button. If continue mode is on, the BSpline tool will restart after you finish or close it, allowing you to draw another one without pressing the BSpline button again.
 * Press while drawing to force snapping your point to the nearest snap location, independently of the distance.
 * Press while drawing to constrain your next point horizontally or vertically in relation to the last one.
 * Press or press the  button to remove the existing segments and start the spline from the last point.
 * Press + or press the button to undo the last point.
 * Press or the  button to have the spline to appear as a face after it has been closed. This simply sets the View->Property of the Wire to "Flat lines" or "Wireframe", so it can easily be changed later.
 * Press or the  button to abort the current BSpline command.
 * BSplines, when in "Flat Lines" display mode, can display a hatch pattern, by setting their "Pattern" property below.

Properties

 * : Specifies if the spline is closed or not
 * : Shows an arrow symbol at the last point of the spline, so it can be used as an annotation leader line
 * : Specifies a hatch pattern to fill the wire with
 * : Specifies the size of the hatch pattern

Script
L'outil peut être utilisé dans des macros, et, dans la console Python, en utilisant cette fonction:


 * Crée un objet B-Spline à partir de la liste des vecteurs donnés.
 * Si closed, a la valeur True, ou que le premier point et le dernier point sont identiques, le wire (fil) est fermé.
 * Si la face est True(et que la bspline est fermée), la bspline apparaîtra pleine.
 * Au lieu d'une liste de points, vous pouvez également passer un Part Wire.
 * Retourne l'objet nouvellement créé.
