* if the mesh is mirrored through a plane:
- * specify the cooordinates of the **Point** lying on the plane, either directly or by picking a mesh node;
+ * specify the coordinates of the **Point** lying on the plane, either directly or by picking a mesh node;
* specify the components of plane **Normal**, either directly or by picking a mesh node, in which case **Normal** is defined as a shift between the **Point** and the node.
* specify the conditions of symmetry operation:
