Hmmmm... I don't understand.
Anyway, how can i change the origin of the model?
I would appreciate any official/unofficial tut on this, if that contains an explanation about this subject.

The latest MED tut - really new

Best MED tutorial: http://www.conitec.net/tutorial/med by Quadraxas

there is also a thing about the origin

Thanks for the link.
Really nice tutorial, unfortunately the way of the origin's change is not explained in there.

"Thanks, but i don't know how could help me to seeing a preference setting."
What?!? MED->File->Preferences.

There you can see the dialog box where you have to check the "Draw Origin" box(es). Then select your whole model and move it using the Move Mode until you're fine with its origin position.

Until you didn't write this:

your info wasn't helpful for me.
I am sorry, as i wrote i am new to MED, so i can't handle those situations when i get only the half of the information.
Anyway i thank to you too the will to help me.

When you don't know how to move something in MED, then you should do at least one MED tutorial first before you go on, otherwise you will waste your and our time and webspace.

That is right, i accept.

Its true. Med is really an absolute basic tool (even if only for
converting stuff) to understand 3dgs development.
Moving a model around is not very complicated, so you should
look into handeling basic functions in MED first.
This makes the further development easier.

Best is to follow the basic tutorial for modeling, so
you know enough about how MED functions.

he mean's:in med select the entire model,move the model to the place where tho tow grids intersect's:

I've got the good answer from alibaba yet.
But i thank all the other people who want to help me and other newbies, especially in such bad situation, when i put a wrong question to here.
