Answer -
Hi-- I personally can't draw what I do not see, or cannot visualize.However, very little of what we draw is completely unique -- there is usually something similar.
Most parts exist in similar form in books, websites, etc.  Once you have seen  "item X", you can draw it in another size or shape. If you have never seen one, you will have to research it or take the the machine apart, to see it. IF there is someone else there who know what it looks like and can give you a hand sketch, then you can draw in AutoCAD.
I hope this helps you.

hi bob. thanks for the reply. my job is copy other machine and create new machine nearly 100% same. so most of the parts must be 100% same. for example bearing hole, cam and shaft. i normally draw 3D. and give dimension. can you show me some of your drawing? my email address is chris_wym@hotmail.com. thanks... see yah...  

Answer
Hi Chris___
I am not completely sure that I understood what you need, but please remember that I am an Interior designer, so my work is not similar.
I regret that I am unable to exchange drawings, etc. Perhaps if you find some online forums for people doing mechanical work, you can make some friends with similar jobs.
Good Luck!
Bob
