 Copy Mesh
 *********
 
-A mesh can be created by copying a part of or the whole other mesh.
+A mesh can be created by copying a part of or the whole other mesh. There are two modes of the operation:
+
+* copy mesh elements only;
+* copy mesh definition to another geometry. This mode can be used only if the source mesh is based on geometry. It is supposed that the new geometry is a modified geometry of the source mesh.

+* select the **New Geometry**;
 * specify the conditions of copying:
 
-  * activate **Generate groups** checkbox to copy the groups of the source mesh to the newly created mesh.
+  * activate **Generate groups** check-box to copy the groups of the source mesh to the newly created mesh. In the mode of copying to new geometry, standalone groups are copied only if **Copy Mesh Elements** is activated.
+  * activate **Reuse hypotheses** check-box to use hypotheses applied to the source mesh in the new mesh. Hypotheses having parameters defined as sub-shapes will be copied independently of this check-box state.
+  * activate **Copy Mesh Element** to copy mesh elements of sub-shapes that are not modified.
 
 * Click **Apply** or **Apply and Close** button to confirm the operation.
 
+When copying the mesh to the new geometry, it can happen that a sub-shape used to define a sub-mesh, group or hypotheses is not found in the new geometry. In this case a new object depending on the not found sub-shape is marked with red color in the Object Browser in order to allow identifying such objects and to fix them, either by modifying their definition or by removing. If a depending object is a group on geometry, a standalone group is created instead. You can't transform it to a group on geometry, it can only be removed and re-created anew.
