By combined, do you mean an actual poly mesh combine? Eg, Edit Mesh>Combine? Just grouping the objects, and deleting the history on that won't have any effect.
I combined all my parts to get a single and deleted history. I am confused at this level. When i combine and delete history, combined individual parts still keep their own histories? What does grouping help ? Combine or group? whats the difference... Thats why i think i need a source to learn the aspects. I know the techniques to visualise but like a 3 year old kid drawing good pictures but in a messy way....

Thanks dave. That model was a different project. I made the model in ZBrush and imported it into maya to keep modelling the mechanical parts. But i experienced that after a while i learned i can't keep modelling with 8M pols.
All I am trying to say is if you take a model into zbrush and try to bring it back to maya with 8 million polys it will not work you have to map them..........dave
