Cubit 16.12 User Documentation
The unite operation combines two or more bodies into a single body. The original bodies are deleted and the new body is given the next highest body ID available, unless the keep option is used. The commands are:
Unite [Volume|BODY] <range> [With [Volume|BODY] <range>] [Keep]
Unite Body {<range> | All} [Keep]
Unite Body {<range> | All} [Include_mesh]
The second form of the command unites multiple bodies in a single operation. If the all option is used, all bodies in the model are united into a single body. If the bodies that are united do not overlap or touch, the two bodies are combined into a single body with multiple volumes.
