I'm trying to model a building which has a gable end ridge shaped skylight placed on a flat roof. I'm getting several following type error message:

* Severe * Problem in interior solar distribution calculation (CHKBKS) * ~~~ * Solar Distribution = FullInteriorExterior will not work in Zone=C5E6ED * ~~~ * because one or more of vertices, such as Vertex 1 of back surface=569D41, is in front of receiving surface=8A7030 * ~~~ * (Dot Product indicator= 0.1385) * ~~~ * Check surface geometry; if OK, use Solar Distribution = FullExterior instead. Use Output:Diagnostics, DisplayExtraWarnings; for more details.

I have checked the geometry seems to be fine. It works completely fine if I model the skylight as a gable roof in the middle of a flat roof. But when I add fenestration on the gabled section, it starts giving me the above error. I would be thankful to receive any insight on how this can be fixed.

I am attaching a link to an image of something similar to what i am trying to build.
