What is the stereodrawing conformation for the ring in the attached compound?
Thanks

I understand that you want the most stable conformation, so read about a cyclohexane conformation: http://en.wikipedia.org/wiki/Cyclohexane_conformation

Thanks but I need to have the most stable conformation for a cyclohexen not cyclohexane. For cyclohexane we get two chair conformations and for cyclohexen two half chair conformations. I don’t know how to draw half chair and the order of the axial and equatorial bonds attaching to the carbons in the ring.
Thanks

That's close. Below are the Chemdraw templates for cyclohexene half-chairs:
