Sphere
======
+
+Sphere feature creates a sphere solid or a part of a sphere solid.
+
+To create a Sphere in the active part:
+
+#. select in the Main Menu *Primitives - > Sphere* item or
+#. click |Sphere_button.icon| **Sphere** button in the toolbar
+
+There are 2 algorithms for creation of a Sphere

+
+**By a center and a radius**
+

+
+**By radii (inner and outer) and angle limits (theta and phi)**
+
+--------------------------------------------------------------------------------
+
+By a center and a radius
+------------------------
+
+Sphere is created by a center (origin by default) and a radius.

+
+Input fields:
+
+- **Point** defines the center of the sphere selected in 3D OCC viewer or object browser;
+- **Radius** defines the radius.
+
+**TUI Command**:
+
+.. py:function:: model.addSphere(Part_doc, Point, Radius)
+
+ :param part: The current part object.
+ :param object: Vertex.
+ :param real: Radius.
+ :return: Result object.
+
+Result
+""""""
+
+A solid sphere based on the origin and a radius.
