How does one turn off snap to surface?

[Tom_P]

this is the rh5 (=V5 - your question ?) topic about osnaps

Object snaps | Rhino 3-D modeling

do you mean you don t want an end/mid/ … point is snapped on the surface ?

you already asked a similar question here:

Snap to one particular layer and ignore all else...how?

Hi, I need to have my line snapping as I progress to draw it, to only those curves on a particular layer, whilst still being able to see other objects (otherwise I could turn off all layers except the two I am working with). How is this done ? Steve

Turn off SnapToLocked, and lock all other layers… --Mitch
