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
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 is4mm
. - DatiMinorRadius (
Length
): The minor radius of the ellipse or elliptical arc. The default is2mm
. - DatiAngle1 (
Angle
): The start angle of the elliptical arc. Valid range:0° < value <= 360°
. The default is0°
. - DatiAngle2 (
Angle
): The end angle of the elliptical arc. Valid range:0° < value <= 360°
. The default is360°
. If DatiAngle1 and DatiAngle2 are equal, or if one angle is0°
and the other360°
, 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()
