Descrizione

Questo comando crea un bordo curvo ellittico. Con i valori di default, il bordo curvo ellittico è chiuso e quindi è una ellisse. Se vengono modificate i valori predefiniti (0 e 360​​) delle proprietà Angolo 0 o Angolo 1, il bordo è una curva aperta, un arco ellittico.

A Part Ellipse is in fact a closed counterclockwise elliptical arc, it can be turned into an arc by changing its DatiAngle1 and/or DatiAngle2 properties.

Utilizzo

See Part Primitives.

Example

Part Ellipse from the scripting example

A Part Ellipse object created with the scripting example below is shown here.

Properties

See also: Property editor.

A Part Ellipse object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

Attachment

The object has the same attachment properties as a Part Part2DObject.

Base

  • DatiMajorRadius (Length): The major radius of the ellipse or elliptical arc. The default is 4mm.
  • DatiMinorRadius (Length): The minor radius of the ellipse or elliptical arc. The default is 2mm.
  • DatiAngle1 (Angle): The start angle of the elliptical arc. Valid range: 0° < value <= 360°. The default is .
  • DatiAngle2 (Angle): The end angle of the elliptical arc. Valid range: 0° < value <= 360°. The default is 360°. If DatiAngle1 and DatiAngle2 are equal, or if one angle is and the other 360°, a full ellipse is created.

Scripting

See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.

A Part Ellipse can be created with the addObject() method of the document:

ellipse = FreeCAD.ActiveDocument.addObject("Part::Ellipse", "myEllipse")
  • Where "myEllipse" is the name for the object.
  • The function returns the newly created object.

Example:

import FreeCAD as App

doc = App.activeDocument()

ellipse = doc.addObject("Part::Ellipse", "myEllipse")
ellipse.MajorRadius = 20
ellipse.MinorRadius = 10
ellipse.Angle1 = 45
ellipse.Angle2 = 135
ellipse.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(30, 45, 10))

doc.recompute()
