How project/Cut a path over sphere I found one tutorial of software PTC Creo 2.0 to try to do the same in Blender, I imported the path from Illustrator like .svg file, place in the zone to project, but when use shrikwrap modifier, nothing happen or deform the path. I post the images of the my process and the tutorial like reference. I reading this link: Some similar question like this... but is a rectangle and my path are irregular form and don´t have the same project form like tutorial.

 













My model before apply modifier...
It looks like "Knife Project" should do exactly what you want to do (described in the manual)

Also, the manual doesn't mention that the projection originates from your point of view. I kept trying to use the tool while "looking" at the objects from the side, and nothing happened. Then this thread wisened me up.
