Popis

Tento nástroj konvertuje Dráty do B-křivek a naopak.

Converting a Draft Wire to a Draft BSpline, and a closed Draft BSpline to a closed Draft Wire

Použití

1. Vyberte drát nebo B-křivku
2. Stiskněte tlačítko Kreslení Drát do B-křivky

Notes

• The command may result in a closed, self-intersecting Draft Wire or Draft BSpline with a face. Such an object will not display properly in the 3D view. Its ÚdajeMake Face property, or its ÚdajeClosed property, must be set to false.

Scripting

Skriptování

Není dostupné, ale vytvoření nového objektu z bodů jiného objektu je snadné, například:

• Je-li aktivní objekt drát:

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)
