I'm using Home Designer Architectural 2019. I'm trying to figure out how to create a glass shower. I used straight interior wall, changed the wall type to glass shower. Added a door changing it to SC02 Glass Door. I can't figure out how to lower the shower walls so they don't go all the way up to the ceiling. I've searched/watched videos but nothing that works for me. Appreciate any help. Thanks in advance! Attached a pic to show my layout.
