I am trying to imprint the smaller surface on the larger surface which is already merged with the two volumes (see pictures attached). I keep getting the following error “Surface 8 cannot be included because it includes higher order topology”. I have tried merging and imprinting all volumes, imprinting surface on another surface, and imprinting surface on volumes but none of those have worked out.
I tried to reproduce your example. Does this help?
