Part Sphere

Description
The Part Sphere command creates a parametric sphere solid. It is the result of revolving a circular arc profile around an axis. In the coordinate system defined by its property, the center of the sphere is positioned at the origin, and its axis of revolution is the Z axis.

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



Usage

 * 1) There are several ways to invoke the command:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) A sphere is created.
 * 5) Optionally change the dimensions and  of the sphere by doing one of the following:
 * 6) * Double-click the object in the Tree view:
 * 7) *# The task panel opens.
 * 8) *# Change the required properties.
 * 9) *# The object updates dynamically in the 3D view.
 * 10) *# Press the button.
 * 11) * Change the properties in the Property editor.
 * 12) * Change the with the [[Image:Std_TransformManip.svg|16px]] Std TransformManip command.

Example


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

Properties
See also: Property editor.

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

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


 * : The radius of the sphere. The default is.
 * : The start angle of the circular arc profile of the sphere. Valid range: . May not be equal to . The default is.
 * : The end angle of the circular arc profile of the sphere. Valid range: . May not be equal to . The default is . If the total angle of the arc profile is smaller than the sphere will be truncated and have a flat face at the top and/or bottom.
 * : The total angle of revolution of the sphere. Valid range: . The default is . If it is smaller than the resulting solid will be a segment of a sphere.

Scripting
A Part Sphere can be created using the following function:


 * Where is the user editable name for the object.
 * The function returns the newly created object.

The label text of the object can be easily changed by

You can access and modify attributes of the object.

For example, you may wish to modify the radius or the three angles of the sphere.

The result will be a part of a sphere, that looks like a piece of cake.

You can change its placement and orientation with:
