CurveStandard Brush issue -

Hi

I have an issue in that when I use the CurveStandard brush is sometimes works, sometimes doesn’t work - on 4R7 - I get the impression you just turn on curves, draw a curve, hold ALT key and sculpt curve outwards but its REALLY unreliable and crazy.

I know some people have been using Zbrush for ten years or whatever, but basically this is driving me insane - is there anything else I should look at in the curves palette or whatever - what is the correct way to use CurveStandard Brush ??
