Beschreibung

Surface FlächeErweitern extrapoliert eine vorhandene Fläche oder Oberfläche an ihren Rändern mit ihren lokalen U- und V-Parametern.

Links: Original Fläche. Rechts: Erweiterte Fläche.

Anwendung

  1. Make sure you have an object that has faces. The object could be created with the Surface Workbench but it could also be any other object, for example, created with Part or PartDesign.
  2. Select the face to extend by clicking on it on the 3D view.
  3. There are several ways to invoke the tool:
    • Press the Extend Face button.
    • Select the Surface → Extend Face option from the menu.

Optionen

Dieser Befehl besitzt keine Optionen. Entweder funktioniert er mit der Auswahl oder nicht.

Eigenschaften

A Surface Extend object (Surface::Extend class) is derived from the basic Part Feature (Part::Feature class, through the Part::Spline subclass), therefore it shares all the latter's properties.

In addition to the properties described in Part Feature, the Surface Filling has the following properties in the property editor.

The Surface Extend tool can be used in macros and from the Python console by adding the Surface::Extend object. 

import FreeCAD as App
import Draft

doc = App.newDocument()

a = App.Vector(-20, -20, 0)
b = App.Vector(-18, 25, 0)
c = App.Vector(60, 26, 0)
d = App.Vector(33, -20, 0)

points = [a, App.Vector(-20, -8, 0), b, c,
          App.Vector(37, 4, 0), d,
          App.Vector(-2, -18, 0), a]
obj = Draft.make_bspline(points)
doc.recompute()

if App.GuiUp:
    obj.ViewObject.Visibility = False

surf = doc.addObject("Surface::Filling", "Surface")
surf.BoundaryEdges = [(obj, "Edge1")]
doc.recompute()

points_spl = [App.Vector(-10, 0, 2),
              App.Vector(4, 0, 7),
              App.Vector(18, 0, -5),
              App.Vector(25, 0, 0),
              App.Vector(30, 0, 0)]

doc.recompute()
