Part Sphere/sv

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) The 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 one or more properties.
 * 9) *# The object is dynamically updated 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.

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.

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


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