how to swap a mesh using an array

Question

I am trying to swap an object in a scene using code. I have successfully done it with materials but some objects require the whole mesh to be changed. can someone help me please my code so far is:

 public var chairs : Mesh[];
 
 
 function ChangeChair(inx : int){
     var meshf : Mesh = GetComponent(MeshFilter).mesh;
     meshf.MeshFilter.mesh = chairs[inx];
 }
 
 function OnGUI(){
     if (GUI.Button (Rect (20,100,80,20), "Chair 1")) {
         ChangeChair(0);
     }
     if (GUI.Button (Rect (20,120,80,20), "Chair 2")) {
         ChangeChair(1);
     }
 }

Your variable meshf contains the mesh itself, not the MeshFilter. And in the second line you try to access the MeshFilter of the mesh, but a mesh doesn't have a MeshFilter, however a MeshFilter has a mesh. What about this:

 function ChangeChair(inx : int){
     var meshf : MeshFilter = GetComponent(MeshFilter);
     meshf.mesh = chairs[inx];
 }

meshf contains the MeshFilter and in the second line the mesh of this filter is assigned. Hope it works :D
