+Building Compounds
+
+Compound Mesh is a combination of several meshes.
+
+ To
+ Build a compound:
+
+From the Mesh
+ menu select Build Compound or
+ click 
button in the toolbar. The following dialog box will
+ appear:
+
+
+
+
+
+ Name
+ - allows selecting the name of the resulting Compound
Meshes
+ - allows selecting the meshes which will be concatenated. They
+ can be chosen in the Object Browser while holding Ctrl
+ button.
Processing
+ identical groups - allows selecting the method of processing the
+ namesake existing on the united meshes. They can be either
United
+ - all elements of Group1
+ on Mesh_1 and
+ Group1 on Mesh_2
+ become the elements of Group1
+ on the Compound_Mesh,
+ or
Renamed
+ - Group1 on
+ Mesh_1 becomes
+ Group1_1 and
+ Group1 on Mesh_2
+ becomes Group1_2.
+ See Creating
+ Groups for more information about groups.
You
+ can simply unite meshes or choose to Merge coincident nodes and
+ elements, in which case it is possible
+ to define the Tolerance for
+ this operation.

+Example:
