For V11 remachining has had a major overhaul to make it much more robust. Spiral (or the spiral portion of a horizontal/vertical combination) remachining is no longer supported. Parallel, Z finish and and parallel/Z finish combination operations are supported. Pencil milling has not been changed and is still supported. As of this version old files with spiral remachining operations will no longer work. The files can be read, but the remachining attributes of the spiral operations will be deleted and they will appear as regular spiral operations.
User Interface
The settings for remachining have been changed and moved to the strategy page of the user-interface. There is no separate "Remachining" page except for pencil milling.
The old settings for "boundary tolerance" and "grid size" are no longer applicable and are gone.
