Описание

Эта команда создаёт эллиптическое изогнутое ребро. При значениях по умолчанию эллиптическое изогнутое ребро будет замкнуто и, следовательно, будет эллипсом. Если свойства Угол(Angle)1 или Угол(Angle)2 отличаются от значений по умолчанию (0 и 360), ребро будет открытой кривой.

A Part Ellipse is in fact a closed counterclockwise elliptical arc, it can be turned into an arc by changing its ДанныеAngle1 and/or ДанныеAngle2 properties.

Применение

See Part Primitives.

Example

Part Ellipse from the scripting example

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

Properties

See also: Property editor.

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

  • ДанныеMajorRadius (Length): The major radius of the ellipse or elliptical arc. The default is 4mm.
  • ДанныеMinorRadius (Length): The minor radius of the ellipse or elliptical arc. The default is 2mm.
  • ДанныеAngle1 (Angle): The start angle of the elliptical arc. Valid range: 0° < value <= 360°. The default is .
  • ДанныеAngle2 (Angle): The end angle of the elliptical arc. Valid range: 0° < value <= 360°. The default is 360°. If ДанныеAngle1 and ДанныеAngle2 are equal, or if one angle is 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()
