zbrush clipcurve other side

montressor

Dear All,

i would like to ask what do I wrong:
I tried to use clipcurve, but it always clip the same side of the model. I drag a cpli line and press alt key, however it changed the white dotted line to a grey it clip the same side as I would not press the alt.
What do I wrong?

thank you very much

ps: sorry for bad enaglish

omg! I create the clipping line starting the other end, so clipping area goes to to the other side.

thank you
