Description
A Part Ellipse is a parametric shape that can be created with the
Part Primitives command. In the coordinate system defined by its DataPlacement property, the ellipse lies on the XY-plane with its center at the origin. Its mayor axis is parallel to the X-axis.
A Part Ellipse is in fact a closed counterclockwise elliptical arc, it can be turned into an arc by changing its DataAngle1 and/or DataAngle2 properties.
Usage
See Part Primitives.
Example

A Part Ellipse object created with the scripting example below is shown here.
Properties
See also: Property View.
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
- DataMajorRadius (
Length): The major radius of the ellipse or elliptical arc. The default is4mm. - DataMinorRadius (
Length): The minor radius of the ellipse or elliptical arc. The default is2mm. - DataAngle1 (
Angle): The start angle of the elliptical arc. Valid range:0° < value <= 360°. The default is0°. - DataAngle2 (
Angle): The end angle of the elliptical arc. Valid range:0° < value <= 360°. The default is360°. If DataAngle1 and DataAngle2 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()
