Hi mir4ea,

> Is it any way to set object at 0.0.0 position?

Select your object, and then run the Transform > Move command:



The prompt in the upper right area of the screen will say "Pick base point" - here you pick the point on the object that you want to relocate. If you want to position the object's bounding box center push the button labeled "Bounding box center" at this stage.

Then after you pick the point you are moving from, the next prompt will say "Pick target point" - this is when you pick the point you want to move to, so in your case you would snap to the origin point or you can also type in 0 and push enter to specify 0,0,0 as the target.
