Subtract one mesh volume from another. The two mesh objects must intersect. The first mesh may be pre-selected. The second mesh will be deleted after the subtraction.Subtract one or more mesh volumes from another. At least one mesh in each selection must intersect. The first set of meshes may be pre-selected. The second set of meshes will be deleted after the subtraction. A Mesh Revolve that is open-ended (not a full 360 degrees) cannot be used in this Subtract function.
 Meshes Must be Closed: If any selected mesh does not form closed volume (i.e., there are any open edges) the Mesh Boolean operations (i.e., Unite, Subtract or Intersect) will fail. This can sometimes occur with imported data files. If this occurs, use the Auto Fix command on each mesh before using the Unit, Subtract or Intersect Mesh commands. You can also use the Diagnose command to check for mesh errors.
