I have model of a head- with a triangular mesh. I then upload the mesh to blender and create a wireframe mesh. I want to project a set of points onto the surface of this mesh (1) and then create cut outs centered around these points (2). I have looked up projecting geometry in blender but I am not sure that is what I am looking for because I am not projecting onto a face but rather around the whole head. Essentially I would like to combine preset- points into an existing mesh and create cut outs in those spots. I am so new to blender I am not sure where else to look.
UPDATE: I have uploaded a picture, I would like to somehow project the geometry on the right onto the surface of the left mesh, and create cut outs centered at the vertices(from the right, that are now on the left).
