Deleting an edge removes each adjacent face.
Deleting a vertex removes all faces that are shared by the vertex.
If removal of a mesh face creates a gap, the mesh object is not watertight.
It can be converted to a surface object, but not to a 3D solid object.
Close Gaps in Mesh Objects
If a mesh object is not watertight due to gaps, or holes, in the mesh, you can
make it watertight by closing the holes. The cap, or new face, spans the
boundary formed by the mesh edges that you specify (MESHCAP).
