Only need the model and stock solid, easy enough to create whatever boundary is required to to the job, we already know his boundary doesn`t work so not much point there.
Anyway, it all seems to be academic, unles the OP joins back in with some files then nothing anyone can do so it doesn`t matter what you, I or anyone else says the exercise has become pretty pointless without the OP
Why people do things like this is beyond me, ask for help and then just leave it hanging, if they have solved it themselves then why not say so ? ? ?
