Part Sphere

Description
Creates a simple parametric sphere, with position, angle1, angle2, angle3 and radius parameters.



Usage

 * 1) Switch to the [[Image:Workbench_Part.svg|16px]] Part Workbench
 * 2) There are several ways to invoke the command:
 * 3) * Press the button in the toolbar.
 * 4) * Select the from the menu bar.

Result: The sphere will be positioned at origin (point 0,0,0) on creation. The angle parameters permit to make a portion of sphere instead of a full sphere (they are set to 360° by default).

The properties of the object can be edited, either in the Property editor or by double-clicking the object in the Tree view.

Data

 * : Radius of the sphere
 * : 1st angle to cut / define the sphere (angle between XZ axis)
 * : 2nd angle to cut / define the sphere (angle between YZ axis)
 * : 3rd angle to cut / define the sphere (angle between XY axis)

Because it is quite difficult to explain the meaning of the parameters angle 1, angle 2, angle 3, the picture below gives an explanation about these parameters with following values: angle 1 = -45°, angle 2 = 45° and angle 3= 90°.



Limitations
If the Angle 1 and Angle 2 values are 'critical' (e.g. both have a value of 45°), the sphere cutoffs are overlapping and the result is invisible.

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:
