+Geometry calculation
+====================
+
+The **Geometry calculation** feature displays basic properties of sub-elements of a geometrical object (shape).
+
+The basic properties displayed in the property panel are lenght, area and volume.
+
+**Apply** button does not generate any result and has the same effect as **Cancel** for this feature.
+
+To display basic properties in the active part:
+
+#. select in the Main Menu *Inspection - > Geometry calculation* item or
+#. click |basicproperties.icon| **Geometry calculation** button in the toolbar
+
+The basic properties can be displayed for a selected object in the property panel :
+
+.. figure:: images/basicPropertiesPropertyPanel.png
+ :align: center
+
+ Geometry calculation
+
+Input fields:
+
+- **Object** contains an object selected in 3D OCC viewer or object browser.
+
+The basic properties displayed can be selected.
