The worldPos parameter appears to be a relative offset to the position of object, so it can often simply be [0,0,0].
Example: to position an object _obj relative to the position of another object _RelObj with on offset of _Offset, try: _Offset = [_x,_y,_z]; _worldPos = _RelObj modelToWorld _Offset; _obj setPos _worldPos;

The object model space has got its Z-Axis along the object's vectorUp, its Y-Axis along the object's vectorDir, while its X-Axis goes along vectorDir x VectorUp (meaning as the X-Axis in a right-handed cartesian coordiante system).

If your object requires a new direction, ensure you call setDir prior to setPos when using modelToWorld. Calling setDir afterwards will skew its position otherwise. _ladder setDir _angle; _ladder setPos (_building modelToWorld [_x, _y, _z]);

The z height returned changes dynamically with the height of waves beneath the object, if the object is located over sea. The z height returned by getPosATL and getPosASL does not change like this. This was tested by continuously retrieving the position of a static object, like the cross in the empty/corpses category, placed over sea or land. modelToWorld behaves similar to getPos _obj but it does not give the same result, therefore (_obj modelToWorld [0.0, 0.0, 0.0]) is not the same as (getPos _obj).
