IntersectMass turns exterior wall to interior wall

Hi,

I seems that sometimes IntersectMasses and SolveAdjacency have problem identifying exterior wall and interior wall. Does anyone know the cause?

Thank you.

Welcome to the forum @XavierZhouLadybug,
Your file is working just fine for me.
Please be aware your units, in the model, are not meters. Maybe becouse of this and becouse the big windows you are asking for (90% of wall) t looks weird.
See the image i produced from your own code with some midifications in the inputs of the glazingCreator component. I’m not showing thw windows just for convenience.

Thank you AbrahamYezioro! How do I check and change the units in the model?

Units is at the bottom of Rhino UI.
