Yeah, that's what I originally meant. My feeling is that 'sculpt' means more to cut or chip away, whereas modeling is more akin to shaping something. But, take your pick...

http://dictionary.reference.com/browse/sculpt "...to carve, model, or make by using the techniques of sculpture."

http://dictionary.reference.com/browse/model "...to fashion in clay, wax, or the like."

But whatever, she's still a bloke I reckon! ;-)
