You could have added a separate model with six vertices which you set passable and to the same angles as the given model, but you already got it working the other way. Good.

As it was explained and underscrored three times
modifying the object is not option.

By the way, thanks for any effort to make something good. Without it this community exists no more.

He didn't talk about modifying the object but about using a dummy model...

OK i understood.
My aim was an elegant solution without any modofication or added dummy model or so...

And thanks for everybody.

It would be also great if somebody try to help me in other problem in The editors section, named Reset rotation values to zero in MED.

Aku_Aku, I didn't notice you being impatient before.
Maybe, you need to relax a bit, because you don't read the posts closely!
Whatever the reason is that you are under stress, I wish you that you get your task done!

Thanks Pappenheimer, you are a great member!
I noticed too, last two weeks i become easily angry, i am impatience and so on... Stress, job and social problems.
I try to handle that, with more or less success.
Anyway it is my problem, but good to hear/read friendly words.
