Are you talking 2D or 3D?
Do you have a picture of the type of stairs you are trying to create that you could post?
I did a search of the forum for stairs and here are the results: http://www.cadtutor.net/forum/search...earchid=104185. Read through some of those threads and see if you get any questions answered.
Edit: Hmmmmm, the link doesn't seem to be working anymore, but you can do your own search. Just type Stair into the search box and browse through the results. Thanks for bringing that to my attention Alan.
