can to path tool NOT to snap to the mesh surface???

i am a newbie of substance painter and i've trying to use the path tool but i found that this tool is extreme hard to use because it will always snap to the surface but i just want to edit its plane coordinates not snap it to the front.

this is what happened after moving it a bit, as the photo see, the point moves to the other mesh which make the whole path become a mess. I want to know is there a way to disable this feature cause it is annoying all the time.
