Curve tri fill brush - geometry disappears?

ZBrush Usage Questions
#1

Ultimate newbie here…sorry…

I want to build up shapes of petals to make a flower using the curve tri fill brush
But every time I go to add new geometry the previous shapes I have drawn disappears, whilst on tutorials they appear to stay put

Any idea where I’m going wrong?
Thanks

You must be watching a tutorial that was done in an older version of ZBrush. Curve functions have changed slightly in ZBrush 4R5. Now, you have to delete the previous curve before you can draw the next. You can do this in two ways. You can click once on the underlying mesh then draw the next curve or you can click ‘Delete’ in ‘Stroke>>Curve Functions’ and draw your next curve.
