Internal Wall in a Zone [createHBZones] [OpenBrep] [HB]

Hello people.
When I use the component createHBZones whit an internal wall whit adiabatic EPBC, the output it’s an open brep. I try to do this because I want to save the geometry including the Internal Wall. Anyone knows how I can add Internal Walls to a Zone and get a closed brep. I already post this question in an older discussion. There are 2 types of geometry in the Rhino file:

  1. Polysurface and Group geometry
  2. Surfaces Ungrouped.

Sorry about my English
