Projection Deformer

The projection deformer moves or, more precisely, projects the points of its superordinated object to it onto a target object to be defined arbitrarily. You can define a projection direction, which is displayed in the view by means of 4 arrows.

If no target object surface is found in the specified direction, corresponding object points will remain unchanged:

If you want to project only parts of an object (e.g., the bottom side), you can, for example, place a linear field in the Fields tab, as shown below:

The lower area of the blue suction cup - defined by a linear field - is projected onto the sphere.
