I have a project where part of the building is office, and part of the building is warehouse. I only need to model the office portion, but I can't figure out how to model the wall between the spaces. Both spaces are fully conditioned, so I don't need to model a partition, I just need one side of my block to be modeled as an interior wall, not a perimeter wall. Any advice on this would be much appreciated.

Thank you

I actually figured this out -- there is a button on the bottom ribbon called "edit surfaces" that allows you to change a wall to interior. I don't see a way to delete this post though.
