A Part Ellipse is a parametric shape that can be created with the Part Primitives command. In the coordinate system defined by its ÚdajePlacement 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 ÚdajeAngle1 and/or ÚdajeAngle2 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

• ÚdajeMajorRadius (Length): The major radius of the ellipse or elliptical arc. The default is 4mm.
• ÚdajeMinorRadius (Length): The minor radius of the ellipse or elliptical arc. The default is 2mm.
• ÚdajeAngle1 (Angle): The start angle of the elliptical arc. Valid range: 0° < value <= 360°. The default is 0°.
• ÚdajeAngle2 (Angle): The end angle of the elliptical arc. Valid range: 0° < value <= 360°. The default is 360°. If ÚdajeAngle1 and ÚdajeAngle2 are equal, or if one angle is 0° 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()
