Description

Descrizione

Crea una sfera parametrica con i parametri posizione, angolo1, angolo2, anglo3 e raggio.

A Part Sphere can be truncated at the top and/or bottom by changing its DatiAngle1 and/or DatiAngle2 properties. It can be turned into a segment of a sphere by changing its DatiAngle3 property.

Usage

Utilizzo

Nell'ambiente Part cliccare sull'icona della sfera . La sfera viene creata nell'origine (punto 0,0,0). I parametri degli angoli consentono di creare una porzione di sfera invece di una sfera intera (sono predefiniti a 360 °).

Example

Part Sphere from the scripting example

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

Notes

  • A Part Sphere can also be created with the Part Primitives command. With that command you can specify the dimensions and placement at creation time.

A Part Sphere 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.

Sphere

  • DatiRadius (Length): The radius of the sphere. The default is 5mm.
  • DatiAngle1 (Angle): The start angle of the circular arc profile of the sphere. Valid range: -90° <= value <= 90°. May not be equal to DatiAngle2. The default is -90°.
  • DatiAngle2 (Angle): The end angle of the circular arc profile of the sphere. Valid range: -90° <= value <= 90°. May not be equal to DatiAngle1. The default is 90°. If the total angle of the arc profile is smaller than 180° the sphere will be truncated and have a flat face at the top and/or bottom.
  • DatiAngle3 (Angle): The total angle of revolution of the sphere. Valid range: 0° < value <= 360°. The default is 360°. If it is smaller than 360° the resulting solid will be a segment of a sphere.

Scripting

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

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

sphere = FreeCAD.ActiveDocument.addObject("Part::Sphere", "mySphere")
  • Where "mySphere" is the name for the object.
  • The function returns the newly created object.

Example:

import FreeCAD as App

doc = App.activeDocument()

sphere = doc.addObject("Part::Sphere", "mySphere")
sphere.Radius = 20
sphere.Angle1 = -30
sphere.Angle2 = 45
sphere.Angle3 = 90
sphere.Placement = App.Placement(App.Vector(3, 9, 11), App.Rotation(75, 60, 30))

doc.recompute()
