Part

A Part Ellipsoid is a parametric solid that can be created with the Part Primitives command. In the coordinate system defined by its ÚdajePlacement property, the axes of the ellipsoid are aligned with the X, Y and Z axes, and therefore its center is positioned at the origin.

A Part Ellipsoid can be truncated at the top and/or bottom by changing its ÚdajeAngle1 and/or ÚdajeAngle2 properties. It can be turned into a segment of an ellipsoid by changing its ÚdajeAngle3 property.

Usage

See Part Primitives.

Example

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

A Part Ellipsoid 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.

Ellipsoid

• ÚdajeRadius1 (Length): The radius of the ellipsoid in its Z direction. The default is 2mm.
• ÚdajeRadius2 (Length): The radius of the ellipsoid in its X direction. The default is 4mm.
• ÚdajeRadius3 (Length): The radius of the ellipsoid in its Y direction. The default is 4mm.
• ÚdajeAngle1 (Angle): The start angle of the elliptical sides of the ellipsoid. Valid range: -90° <= value < 90°. Must be smaller than ÚdajeAngle2. The default is -90°.
• ÚdajeAngle2 (Angle): The end angle of the elliptical sides of the ellipsoid. Valid range: -90° < value <= 90°. Must be larger than ÚdajeAngle1. The default is 90°. If the total angle of the elliptical sides is smaller than 180° the ellipsoid will be truncated and have a flat face at the top and/or bottom.
• ÚdajeAngle3 (Angle): The total angle of the ellipsoid in its XY plane. Valid range: 0° < value <= 360°. The default is 360°. If it is smaller than 360° the resulting solid will be a segment of an ellipsoid.

Scripting

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

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

ellipsoid = FreeCAD.ActiveDocument.addObject("Part::Ellipsoid", "myEllipsoid")

• Where "myEllipsoid" is the name for the object.
• The function returns the newly created object.

Example:

import FreeCAD as App

doc = App.activeDocument()

ellipsoid = doc.addObject("Part::Ellipsoid", "myEllipsoid")
ellipsoid.Radius1 = 2
ellipsoid.Radius2 = 4
ellipsoid.Radius3 = 6
ellipsoid.Angle1 = -90
ellipsoid.Angle2 = 50
ellipsoid.Angle3 = 300
ellipsoid.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(15, 0, 20))

doc.recompute()
