Part Ellipsoid

Description

A Part Ellipsoid is a parametric solid that can be created with the Part Primitives command. In the coordinate system defined by its Placement 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 Angle1 and/or Angle2 properties. It can be turned into a segment of an ellipsoid by changing its Angle3 property.

Usage

See Part Primitives.

Example

Part Ellipsoid from the scripting example

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

Properties

See also: Property editor.

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

Data

{{TitleProperty|Attachment}}

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

{{TitleProperty|Ellipsoid}}

  • Radius1|Length: The radius of the ellipsoid in its Z direction. The default is {{Value|2mm}}.

  • Radius2|Length: The radius of the ellipsoid in its X direction. The default is {{Value|4mm}}.

  • Radius3|Length: The radius of the ellipsoid in its Y direction. The default is {{Value|4mm}}.

  • Angle1|Angle: The start angle of the elliptical sides of the ellipsoid. Valid range: {{Value|-90° <= value < 90°}}. Must be smaller than Angle2. The default is {{Value|-90°}}.

  • Angle2|Angle: The end angle of the elliptical sides of the ellipsoid. Valid range: {{Value|-90° < value <= 90°}}. Must be larger than Angle1. The default is {{Value|90°}}. If the total angle of the elliptical sides is smaller than {{Value|180°}} the ellipsoid will be truncated and have a flat face at the top and/or bottom.

  • Angle3|Angle: The total angle of the ellipsoid in its XY plane. Valid range: {{Value|0° < value <= 360°}}. The default is {{Value|360°}}. If it is smaller than {{Value|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 {{Incode|addObject()}} method of the document:

ellipsoid = FreeCAD.ActiveDocument.addObject("Part::Ellipsoid", "myEllipsoid")
  • Where {{Incode|"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()
