Hi, I'm creating renderings for an architect in HD Architectural 2017. His design has a new 1.75 story open volume Outdoor Verandah with a bar area that has a nearby "closet" size pantry space. The pantry structure has a one story 9' plate tiled hip/shed roof. A boxed-in fireplace flue sits over part of the pantry roof from an existing fireplace in an adjacent room on first floor below.
My problem is when I try to put a ceiling over the entire high 1.75 story volume space at +18' I can't get that high roof to span over and above the one story 9' pantry roof below. I tried creating an invisible "room" on second floor to project out over the pantry, but I can't figure out how to work this with the existing window and fireplace flue elements in place.
I've read through all of the manual sections on roofs; looked at many published HD roof videos, and searched the forum, but so far can't find a similar setup from which to interpolate.
I understand that this portion of the high roof is being excluded because the Verandah room itself is divided at the pantry wall so the pantry becomes a room in itself and it effectively creates a void exactly the size of the pantry roof in the second ceiling above.
Can a higher roof structure be designed to span completely over a lower roof below, or is there a method to close the void opening in high the ceiling above the one story pantry? The exterior roof design does not matter--I'm only providing interior views for this space.
