Hi. who can tell me is there Accurate curve mode in ZB 3.1I am going to try to play with hard surface but can`t to find out where this button is situated 
Maybe this update does not contain this function.
The ‘Accurate’ mode is in the Brush palette. Press this button and then modify the Edit Curve (at the bottom of the Brush palette, just above the Smooth curve) to control the profile of the curve.
To test this…
1.Press ‘Accurate’ mode
2.press ‘Reset’ in the Edit Curve
3.Select DragRect storke.
Applying a stoke to a mesh with these settings will produce a cone shape.
“To test this…
1.Press ‘Accurate’ mode”
<Heh, I know)), it look as madness, but where I should to press this button. Here I found in the earlier post “go Transform/ Modifiers/ Accurate curve mode and turn it on…”
< In Transform is noting(( The model is polymeshe(Please,someone,can you attach image. I`m blind)
