Descrizione

Il comando Draft Polilinea in B-spline converte Draft Polilinee in Draft B-splines e viceversa.

Conversione di un Draft Polilinea in un Draft B-spline e di una Draft B-spline chiusa in una Draft Polilinea chiusa

Utilizzo

1. Selezionare una Draft Polilinea o una Draft B-spline.
2. Ci sono diversi modi per invocare il comando:
   • Premere il pulsante Polilinea in B-spline.
   • Selezionare l'opzione Modifiche → Polilinea in B-spline dal menu.
3. Viene creato un nuovo oggetto.

Note

• Il comando potrebbe far risultare una Draft Polilinea o Draft B-spline autointersecante con una faccia. Tale oggetto non verrà visualizzato correttamente nella Vista 3D. La sua proprietà DatiMake Face, o la sua proprietà DatiClosed, deve essere impostata su false.

Script

Vedere anche: Autogenerated API documentation e Script di base per FreeCAD.

Per convertire una Polilinea in una B-spline, o viceversa, passare la proprietà Points dell'oggetto sorgente al metodo make_bspline, o rispettivamente al metodo make_wire, del modulo Draft.

Esempio:

import FreeCAD as App
import Draft

doc = App.newDocument()

p1 = App.Vector(1000, 1000, 0)
p2 = App.Vector(2000, 1000, 0)
p3 = App.Vector(2500, -1000, 0)
p4 = App.Vector(3500, -500, 0)

base_wire = Draft.make_wire([p1, p2, p3, p4])
base_spline = Draft.make_bspline([-p1, -1.3*p2, -1.2*p3, -2.1*p4])

points1 = base_wire.Points
spline_from_wire = Draft.make_bspline(points1)

points2 = base_spline.Points
wire_from_spline = Draft.make_wire(points2)

doc.recompute()
