Input faces does not form a closed volume

Hello,

I have some bug, the component hb room report error “Input faces does not form a closed volume” this bug apparently come from component opaque construction who have a dashed line.

when i delete one of the three material of this component like “generic concrete HW” its work fine, i don’t know why ?

You just need to flatten the merge component output.
For some reason you are using 2 insulation material definitions and creating a construction out of them. I’m assuming this is only for testing purposes.
