Surfaces

I want to:

One

Project a vertex into other surfaces.
(Have two layers of a mesh an cutter a hole in one and want to get the exact hole in the other layer.

Two

Engrave symbols on a surfaces, symbols are meshes.

Thank you for your time :smiley_cat:.

You need to explain (1) better. A boolean will do the latter part of the question.

  1. A boolean will also work, depending on how you set up[ your meshes.

Need more detail or a blend file to know exactly what you’re trying to do.

Elaboration:

One

I want to project the cut I made in the front sphere to the one in the back so I get the same cut. Hence, the ball looks cracked.

Two

I will create symbols as meshes and then I would like to Embbed them on to the smooth surface.
Symbols are not ready yet. But will be created soon
