Descrizione
Questo strumento converte i segmenti di una linea spezzata, qui definita DWire, in curve di tipo BSpline, e viceversa.
Convertir a wire to a B-Spline, and a closed B-Spline to a closed wire
Utilizzo
- Selezionare una linea Wire o una BSpline
- Premere il pulsante Template:KEY/it
A new object will be created; the original object will not be modified.
Note: if a closed wire with sharp edges is used to create a spline, the new object may have self intersecting curve segments, and may not be visible in the 3D view. If this is the case, manually set DatiMake Face to false
to see the new shape, or set DatiClosed to false
to create an open shape.
Opzioni
- L'oggetto originale non viene eliminato dopo l'operazione, è necessario eliminarlo manualmente, se lo si desidera.
Script
Non è disponibile, ma è facile creare un nuovo oggetto usando i punti di un altro oggetto, per esempio:
The Points
attribute of an object is a list with the points that comprise that object; this list can be passed to functions that build geometry. Each point is defined by its FreeCAD.Vector
, with units in millimeters.
- se l'oggetto attivo è una linea wire
import FreeCAD, Draft
# Make a spline from the points of a wire
p1 = FreeCAD.Vector(1000, 1000, 0)
p2 = FreeCAD.Vector(2000, 1000, 0)
p3 = FreeCAD.Vector(2500, -1000, 0)
p4 = FreeCAD.Vector(3500, -500, 0)
base_wire = Draft.makeWire([p1, p2, p3, p4])
points1 = base_wire.Points
spline = Draft.makeBSpline(points1)
# Make a wire from the points of a spline
base_spline = Draft.makeBSpline([-p1, -1.3*p2, -1.2*p3, -2.1*p4])
points2 = base_spline.Points
Wire = Draft.makeWire(points2)
