3D Model Size

Question

Hi,
With this script i want to find out the size of 3d model. But it does not work correctly: some models has the same size like in 3d program, other has a diferent size. Specialy by models with more than 1 mesh is the size calculation not corect. What is wrong on my script?
  myworld = member("3dmember")
  myworld.model (1).addModifier(#meshdeform)
myvertexlist = (myworld.model[1].meshdeform.mesh[1].vertexlist)
  maxmin = [myvertexlist.max().x,myvertexlist.min().x,myvertexlist.max().y,myvertexlist.min().y,myve rtexlist.max().z,myvertexlist.min().z]
    repeat with n = 1 to myworld.model[1].meshdeform.mesh.count
    Nvertexlist = (myworld.model[1].meshdeform.mesh[n].vertexlist)
    if Nvertexlist.max().x > getAt(maxmin, 1) then
      setAt maxmin, 1, Nvertexlist.max().x
    end if
    if Nvertexlist.min().x < getAt(maxmin, 2) then
      setAt maxmin, 2, Nvertexlist.min().x
    end if
    if Nvertexlist.max().y > getAt(maxmin, 3) then
      setAt maxmin, 3, Nvertexlist.max().y
    end if
    if Nvertexlist.min().y < getAt(maxmin, 4) then
      setAt maxmin, 4, Nvertexlist.min().y
    end if
    if Nvertexlist.max().z > getAt(maxmin, 5) then
      setAt maxmin, 5, Nvertexlist.max().z
    end if
    if Nvertexlist.min().z < getAt(maxmin, 6) then
      setAt maxmin, 6, Nvertexlist.min().z
    end if
  end repeat
  SizeX = getat (maxmin, 1) - getat (maxmin, 2)
  SizeY = getat (maxmin, 3) - getat (maxmin, 4)
  SizeZ = getat (maxmin, 5) - getat (maxmin, 6)
  put SizeX * 2.54
  put SizeY * 2.54
  put SizeZ * 2.54
Thanks for any ideas.

Imagine scenario: you import wrong scaled model into 3d world, you know the real sizes(height, width, length) of the model. Which scale factor you need to correct the model size?
I never had to deal with that scenario in the past 10 years.
Simply because I own the sources of the 3D models.
A W3D file is not a source file and Director Shockwave is not a 3D modeler.
