How do i draw isometric tiles in 3d max so that thy fit?

What do u mean, thy fit? All of them must be the smae size?

If so, then put a square grid and place the camera in that way so you''ll see the grid in the way u want. After, when making a new tile, just apply a new texture to that grid. That''s it..

I''ve tried to make tiles once on 3d Studio, and all I couldn''t get it to work. It''s too hard to get different tiles to blend in with eachother.
