creating open air courtyard in cent of the house

[Dan Park]

I am assuming that you are marking the courtyard room as Court. This defines the room as having no roof or ceiling. If this is the case and the court has the roof and ceiling attribute unchecked try rebuilding the roof. If that does not work we may need to look at the plan.

Also as I understand the problem you have the walls drawn with the siding on the wrong side then when you flip them they are on the right side. However when you save the plan and reopen it the plan reverts back to the original.

You might try saving the plan with a new filename then reopen it and see if we have the same problem.
