A [[Image:Part_Ellipsoid.svg|24px]] '''Part Ellipsoid''' is a parametric solid that can be created with the [[Image:Part_Primitives.svg|24px]] [[Part_Primitives|Part Primitives]] command. In the coordinate system defined by its {{PropertyData|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 {{PropertyData|Angle1}} and/or {{PropertyData|Angle2}} properties. It can be turned into a segment of an ellipsoid by changing its {{PropertyData|Angle3}} property.

Example:
The shape produced is limited in FreeCAD to being a solid (optionally truncated) spheroid, the shape you would create by rotating an ellipse around one of its axis. By default it is a [http://en.wikipedia.org/wiki/Oblate_spheroid oblate_spheroid], the shape you would create by rotating an ellipse around its minor axis.

Descriere

Un solid parametric este Elipsoidul care este disponibil din dialogul Create Primitives în Atelierul de lucru Part.

A Part Ellipsoid is a parametric solid that can be created with the Part Primitives command. In the coordinate system defined by its DatePlacement 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 DateAngle1 and/or DateAngle2 properties. It can be turned into a segment of an ellipsoid by changing its DateAngle3 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.

Proprietăți

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

Attachment

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

Ellipsoid

  • DateRadius1 (Length): The radius of the ellipsoid in its Z direction. The default is 2mm.
  • DateRadius2 (Length): The radius of the ellipsoid in its X direction. The default is 4mm.
  • DateRadius3 (Length): The radius of the ellipsoid in its Y direction. The default is 4mm.
  • DateAngle1 (Angle): The start angle of the elliptical sides of the ellipsoid. Valid range: -90° <= value < 90°. Must be smaller than DateAngle2. The default is -90°.
  • DateAngle2 (Angle): The end angle of the elliptical sides of the ellipsoid. Valid range: -90° < value <= 90°. Must be larger than DateAngle1. 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.
  • DateAngle3 (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()
