create prefab of fbx

hii, i have number of fbx files. And as we know prefab is collection of gameobjects.

so i need to add all my fbx files in to one prefab.beacauz my aim is , that certain prefab will be parent for all of them.

how many ways are there in unity or if there is any way in maya of 3ds max, to make prefab of number of fbx files, let me know.

Any help will be helpful

Thanks,

Bring in all your FBX files into a scene in unity. Align them how you want them to look/parent together. then in the project tab create a new prefab, select all your pieces in the hierarchy and drag them all together into the new prefab. Name this accordingly and you will be done :)

@AngryOldMan the prefab that I make does not save info from adjustmnet I made to original FBX in the scene. WHen I drag the prefab its still the same as imported fbx. Any Idea?
