Placing 3d model onmouseclick

Hi,

I am trying to place a 3d model onmouseclick event. Right now i am able to get position on the terrain using raycast, so 'll have the coordinate where i want to place the object but the problem is how to create an object and place it on that coordinates.

please suggest me tips/tricks for that.

code to detect coordinates on terrain:

 void Update () 
 {
     if(Input.GetMouseButtonDown(0))
     {
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         if(Physics.Raycast(ray, out hit1))
         {
             transform.position = hit1.point;
         }
     }
 }

i have searched on net regarding this and i found instantiating the object, but i think this is not exactly what i am looking for, here's the code:

 Instantiate(Object, hit1.point, Quaternion.identity);

UPDATE:

I have found this useful link which places model on mouseclick.

SEE HERE for mouseplacement script.

and suggest how can i place 3d models like Tank, weapons etc....
