Cubit 15.7 User Documentation
The chop command works similarly to a web cut command, but is faster. Given two bodies, the command will find the intersection of the two bodies, and divide the main body into a body that lies outside the intersection, and a body that lies inside the intersection. The tool body will be deleted, unless the keep option is specified. The syntax of the command is:
Chop [Volume|BODY] <id> with [Volume|BODY] <id> [keep] [nonreg]
The nonreg option results in the bodies being non-regularized.
